Description

Method, device, equipment and medium for determining correction coefficient of construction trap volume

Technical Field

The invention relates to the technical field of geological research, in particular to a method, a device, equipment and a medium for determining a correction coefficient of a structure trap volume.

Background

The formation trap volume is a direct parameter that predicts the potential of hydrocarbon resources stored within the formation trap, and is typically calculated by multiplying the bottom area by the reservoir thickness. However, the construction trap volume determined in this way has a large error from the actual situation, and a volume correction coefficient is usually introduced to correct the calculated construction trap volume. Therefore, how to accurately calculate the volume correction coefficient of the structure trap becomes the biggest bottleneck restricting the prediction accuracy of the structure trap resource amount.

In the prior art, the correction coefficient of the construction trap volume is usually given when the construction trap resource quantity is predicted according to personal experience or by adopting an expert scoring method, and even the influence of the parameter on the resource quantity prediction result is directly ignored. The construction trap resource quantity obtained by the method is usually overestimated or underestimated in construction trap volume, and obvious errors exist in the result, so that the underground real resource potential cannot be truly reflected, and the exploration potential evaluation and the exploration scheme deployment of the construction trap are directly influenced.

Wherein, the structural trap can refer to a trap formed by the deformation of the reservoir rock stratum and the upper cover layer thereof due to a certain local structure. The construction trap to be tested may refer to a waiting to detect construction trap. The trap type can be used for representing the type of the construction trap, and particularly can comprise three types of anticline type, anticline type and block type. The standard cross section may refer to a representative cross section selected for determining a volume correction factor for the trap of the structure to be tested, and may be used to represent the plane of the bottom surface of the trap of the structure to be tested. It should be noted that, the selection of the standard cross section is related to the trap type of the to-be-tested construction trap, and different representative standard cross sections need to be selected correspondingly because the to-be-tested construction traps of different trap types have different construction characteristics.

In this embodiment, firstly, the trap type of the trap of the structure to be tested is determined, and then, the standard cross section of the trap of the structure to be tested is determined according to the trap type. The standard cross section is determined according to the cross section of a target line segment in a construction trapping range to be detected, wherein when the trapping type is a anticline type, the target line segment is a line segment passing through an anticline central point in the construction trapping range to be detected, the length of the target line segment is equal to the average length of a first reference line segment and a second reference line segment, the first reference line segment and the second reference line segment are respectively a longest line segment and a shortest line segment passing through the anticline central point in the construction trapping range to be detected, when the trapping type is a anticline type, the target line segment is a line segment perpendicular to a control ring fault in the construction trapping range to be detected, the length of the target line segment is equal to half of the length of a third reference line segment, the third reference line segment is a longest line segment perpendicular to the control ring fault in the construction trapping range to be detected, when the trapping type is a fault type, the target line segment is a line segment parallel to the fourth reference line segment in the trapping range to be detected, the length of the target line segment is equal to half of the length of the fourth reference line segment, and the fourth reference line segment is a connecting two control ring faults and a construction overflow point in the fault trapping range to be detected.

The target line segment can be used as a direct basis for selecting the standard cross section. Specifically, the standard cross section is determined according to the cross section where the target line segment in the trapping range of the to-be-detected structure is located. Fig. 2A is a schematic diagram of a standard cross section of a back-inclined structure trap according to an embodiment of the present invention. As shown in the left diagram of fig. 2A, aa ^′ represents a target line segment, bb ^′ represents a longest line segment (i.e., a first reference line segment) passing through a anticline center point within the anticline configuration trap, cc ^′ represents a shortest line segment (i.e., a second reference line segment) passing through the anticline center point within the anticline configuration trap, aa ^′ passes through the anticline center point within the anticline configuration trap, and aa ^′ has a length equal to the average length of bb ^′ and cc ^′. As shown in the right hand graph of fig. 2A, L _r and H _r represent the reservoir cross-sectional length and reservoir cross-sectional thickness, respectively, over the range of anticline trap on standard cross-section at the ideal angle, where ideal angle means that the reservoir dip is 0 degrees. It should be noted that, the position of the target line aa ^′ is a mean position showing the influence of L _r on the area of the trap bottom of the anticline structure, so that the selected standard cross section is representative.

As shown in the right hand graph of fig. 2B, L _r and H _r represent the reservoir cross-sectional length and reservoir cross-sectional thickness, respectively, over the range of a back-off-diagonal trap on a standard cross-section at an ideal angle. It should be noted that, the position of the target line aa ^′ is a mean value position showing the influence of L _r on the trap bottom area of the back-inclined-broken structure, so that the selected standard cross section is representative.

Fig. 2C is a schematic diagram of a standard cross section of a broken block type structure trap according to an embodiment of the present invention. As shown in the left diagram of fig. 2C, aa ^′ represents a target line segment, bb ^′ represents a line connecting two control ring faults within the break-block trap with the point of intersection of the contour of the construction overflow point (i.e., a fourth reference line segment), where aa ^′ is parallel to bb ^′ and aa ^′ is equal to half the length of bb ^′. As shown in the right hand graph of fig. 2C, L _r and H _r represent the reservoir cross-sectional length and reservoir cross-sectional thickness, respectively, over the range of a break-block trap on a standard cross-section at an ideal angle. It should be noted that, the position of the target line aa ^′ is a mean value position showing the influence of L _r on the trap bottom area of the block-type structure, so that the selected standard cross section is representative.

S120, determining target parameter information of the structure to be tested, which is trapped on the standard cross section, and determining a reference correction coefficient of the structure to be tested according to the target parameter information, wherein the reference correction coefficient comprises at least two of an amplitude correction coefficient, a fault correction coefficient and a reservoir correction coefficient.

The target parameter information can be used as a basis for determining a reference correction coefficient of the trap of the to-be-detected structure, and needs to be matched with the trap type, namely, different trap types correspond to different target parameter information. The reference correction coefficient can be used as a basis for determining the volume correction coefficient of the trap of the structure to be tested, and the reference correction coefficient is required to be matched with the trap type, namely, different reference correction coefficients corresponding to different trap types are required. Wherein the reference correction coefficients include at least two of an amplitude correction coefficient, a fault correction coefficient, and a reservoir correction coefficient. The method comprises the steps of setting a reference correction coefficient, wherein the reference correction coefficient comprises an amplitude correction coefficient and a reservoir correction coefficient when the trap type is a anticline type, comprises an amplitude correction coefficient, a fault correction coefficient and a reservoir correction coefficient when the trap type is a anticline type, and comprises a fault correction coefficient and a reservoir correction coefficient when the trap type is a block type.

The amplitude correction coefficient is determined according to the ratio of a first cross-sectional area to a second cross-sectional area, the first cross-sectional area is determined based on a first reference area, the first reference area is the cross-sectional area of the structure to be tested, which is influenced by the amplitude of the top surface, the second cross-sectional area is determined based on a second reference area, the second reference area is the cross-sectional area of the structure to be tested, which is in an ideal angle, the ideal angle is the dip angle of the reservoir, the fault correction coefficient is determined according to the ratio of a third cross-sectional area to the second cross-sectional area, the third cross-sectional area is determined based on a third reference area, the third reference area is the cross-sectional area of the structure to be tested, which is influenced by the fault of the controlled loop of the structure to be tested, the fourth cross-sectional area is determined based on a fourth reference area, and the fourth reference area is the cross-sectional area of the structure to be tested, which is influenced by the occurrence of the dip of the reservoir.

In this embodiment, after determining the corresponding standard cross section according to the trap type of the to-be-measured structure trap, it is necessary to further determine the target parameter information of the to-be-measured structure trap on the standard cross section, and determine the reference correction coefficient of the to-be-measured structure trap according to the target parameter information.

In the embodiment, optionally, a reference correction coefficient of a construction trap to be detected is determined according to target parameter information, wherein the reference correction coefficient comprises a first amplitude parameter information and a first amplitude function in target parameter information when the trap type is anticline, the first amplitude parameter information comprises a reservoir cross section length and a reservoir cross section thickness in a construction trap range to be detected on a standard cross section under an ideal angle, a left wing top surface inclination angle and a right wing top surface inclination angle of the construction trap to be detected on the standard cross section, the first amplitude function is used for describing a mapping relation between the first amplitude parameter information and the amplitude correction coefficient, and the amplitude correction coefficient of the construction trap to be detected is determined according to a second amplitude parameter information and the second amplitude function in the target parameter information when the trap type is anticline, wherein the second amplitude parameter information comprises the reservoir cross section length and the reservoir cross section thickness in the construction trap range to be detected on the standard cross section under the ideal angle, and the inclination angle of the construction trap to be detected on the standard cross section, and the second amplitude function is used for describing a mapping relation between the second amplitude parameter information and the amplitude correction coefficient.

The first amplitude parameter information may refer to parameter information associated with determining an amplitude correction coefficient among target parameter information of the anticline construction trap. The first amplitude parameter information comprises the length of a reservoir cross section and the thickness of the reservoir cross section in the trapping range of the structure to be tested on the standard cross section under an ideal angle, and the top surface inclination angle of the left wing and the top surface inclination angle of the right wing of the structure to be tested on the standard cross section. The first amplitude function may be a preset function relation for determining the back-inclined construction trap amplitude correction coefficient, and may be used for describing a mapping relation between the first amplitude parameter information and the amplitude correction coefficient. For example, the first amplitude function may be set to c=h _r(cotα₁+cotα_r)/2L_r, where C is an amplitude correction factor, L _r and H _r are the reservoir cross-sectional length and the reservoir cross-sectional thickness, respectively, in the range of the anticline trap on the standard cross-section at the ideal angle, and α ₁ and α _r are the left-wing top-surface tilt and the right-wing top-surface tilt, respectively, of the anticline trap on the standard cross-section.

Specifically, as shown in the right-hand drawing of fig. 2A, the cross-sectional area (i.e., the second cross-sectional area) of the anticline configuration trapped at the desired angle may be denoted as L _r×H_r. Fig. 3A is a schematic diagram of a anticline structure trapping a first cross-sectional area according to an embodiment of the present invention. Wherein the first cross-sectional area may be used to characterize a cross-sectional area of the anticline formation trap caused by the amplitude of the top surface. As shown in FIG. 3A, the first cross-sectional area may be expressed as 1/2 XH _r×H_r×(cotα₁+cotα_r). Thus, the first amplitude function may be denoted C＝1/2×H_r×H_r×(cotα₁+cotα_r)/(L_r×H_r)＝H_r(cotα₁+cotα_r)/2L_r. further, and when α ₁＝α_r =α, the first amplitude function may be denoted c=h _r cotα/L_r. For the anticline type structure trap, after the target parameter information is obtained, the first amplitude parameter information in the target parameter information can be substituted into the first amplitude function, and the amplitude correction coefficient of the anticline type structure trap is obtained through calculation.

The second amplitude parameter information may refer to parameter information associated with determining the amplitude correction coefficient among target parameter information of the back-off oblique configuration trap. The second amplitude parameter information comprises the length of the reservoir cross section and the thickness of the reservoir cross section in the trapping range of the structure to be tested on the standard cross section under the ideal angle, and the top surface inclination angle of the structure to be tested on the standard cross section. The second amplitude function may be a preset function relation for determining an amplitude correction coefficient of the back-inclined broken structure trap, and may be used for describing a mapping relation between the second amplitude parameter information and the amplitude correction coefficient. It should be noted that the second amplitude function and the first amplitude function may be set to the same function form, or may be set to different function forms, and may be specifically set according to actual requirements.

For example, if the second amplitude function and the first amplitude function have the same function form, for example, if the second amplitude function is also set to c=h _r(cotα₁+cotα_r)/2L_r, where L _r and H _r respectively represent a reservoir cross-sectional length and a reservoir cross-sectional thickness within a range of a broken anticline trap on a standard cross-section at an ideal angle, α ₁ represents a top surface inclination of the broken anticline trap on the standard cross-section, and α _r is absent (this is omitted). If the second amplitude function and the first amplitude function have different function forms, the second amplitude function may be directly set to c=h _r cotα/2L_r, where α represents the inclination of the top surface of the broken anticline trapped on the standard cross section. Specifically, as shown in the right-hand drawing of fig. 2B, the cross-sectional area (i.e., the second cross-sectional area) of the broken anticline configuration trapped at the desired angle may be denoted as L _r×H_r. Fig. 3B is a schematic diagram of a broken back inclined structure trapping a first cross-sectional area according to a first embodiment of the present invention. Wherein the first cross-sectional area is used to characterize the cross-sectional area of the broken anticline construction trap caused by the influence of the top surface amplitude. As shown in FIG. 3B, the first cross-sectional area may be expressed as 1/2 XH _r×H_r Xcotα. Thus, the second amplitude function may be expressed as c=1/2×h _r×H_r×cotα/(L_r×H_r)＝H_r cotα/2L_r. For the back-inclined-broken structure trap, after the target parameter information is obtained, the second amplitude parameter information in the target parameter information can be substituted into the second amplitude function, and the amplitude correction coefficient of the back-inclined-broken structure trap is obtained through calculation.

When the trap type is a block type, neither α ₁ nor α _r is present, and the amplitude correction coefficient is not required to be considered, so that the amplitude correction coefficient of the block type structure trap may be directly set to 0. Thus, the amplitude correction coefficients of the three structural traps can be respectively solved by setting a common amplitude function.

In the embodiment, optionally, a reference correction coefficient of a construction trap to be detected is determined according to target parameter information, wherein the reference correction coefficient comprises a fault correction coefficient of the construction trap to be detected according to first fault parameter information and a first fault function in the target parameter information when the trap type is back inclined, the first fault parameter information comprises a reservoir cross section length and a reservoir cross section thickness in a construction trap range to be detected on a standard cross section under an ideal angle, a control ring inclination angle of the construction trap to be detected on the standard cross section, the first fault function is used for describing a mapping relation between the first fault parameter information and the fault correction coefficient, and the fault correction coefficient of the construction trap to be detected is determined according to second fault parameter information and the second fault function in the target parameter information when the trap type is broken block type, and the second fault parameter information comprises a reservoir cross section length and a reservoir cross section thickness in the construction trap range to be detected on the standard cross section under the ideal angle, and a left wing ring inclination angle and a right wing ring inclination angle of the construction trap to be detected on the standard cross section.

The first fault parameter information may be parameter information associated with determining a fault correction coefficient among target parameter information of the back-off oblique type structure trap. The first fault parameter information comprises the length of a reservoir cross section and the thickness of the reservoir cross section in the trapping range of the structure to be detected on the standard cross section under an ideal angle, and the inclination angle of a control loop fault of the structure to be detected trapped on the standard cross section. The first fault function may be a preset function relationship for determining a fault correction coefficient of the back-inclined fault structure trap, and may be used to describe a mapping relationship between the first fault parameter information and the fault correction coefficient. For example, the first fault function may be set to f=h _r tanβ/2L_r, where F represents a fault correction coefficient, L _r and H _r are the reservoir cross-sectional length and the reservoir cross-sectional thickness, respectively, within the range of a back-off-tilt trap on a standard cross-section at an ideal angle, and β is the controlled-circle fault tilt angle of the back-off-tilt trap on the standard cross-section.

Specifically, as shown in the right-hand drawing of fig. 2B, the cross-sectional area (i.e., the second cross-sectional area) of the broken anticline configuration trapped at the desired angle may be denoted as L _r×H_r. Fig. 4A is a schematic diagram of a broken back inclined structure trapping a third cross-sectional area according to a first embodiment of the present invention. Wherein the third cross-sectional area may be used to characterize the cross-sectional area caused by the controlled trapping fault effect of the anticline formation trap. As shown in FIG. 4A, the third cross-sectional area may be expressed as 1/2 XH _r×H_r Xtan beta. Thus, the first fault function may be expressed as f=1/2×h _r×H_r×tanβ/(L_r×H_r)＝H_rtanβ/2L_r. For the back-cut oblique type structure trap, after the target parameter information is obtained, the first fault parameter information in the target parameter information can be substituted into the first fault function, and the fault correction coefficient of the back-cut oblique type structure trap is obtained through calculation.

The second tomographic parameter information may be parameter information associated with determining the tomographic correction coefficient among target parameter information of the block-type structure trap. The second fault parameter information comprises the length of a reservoir cross section and the thickness of the reservoir cross section in the trapping range of the structure to be detected on the standard cross section under an ideal angle, and the fault inclination angle of the left wing control ring and the fault inclination angle of the right wing control ring of the structure to be detected on the standard cross section. The second fault function may be a preset function relationship of fault correction coefficients for determining fault block type structure trap, and may be used to describe a mapping relationship between second fault parameter information and the fault correction coefficients. For example, the second fault function may be set to f=h _r(tanβ₁+tanβ_r)/2L_r, where L _r and H _r represent the reservoir cross-sectional length and reservoir cross-sectional thickness, respectively, within the range of a broken block-type trap on a standard cross-section at an ideal angle, and β ₁ and β _r represent the left and right wing control ring fault angles, respectively, of the broken block-type trap on the standard cross-section.

Specifically, as shown in the right-hand drawing of fig. 2C, the cross-sectional area (i.e., the second cross-sectional area) of the segmented construction trapped at the desired angle may be denoted as L _r×H_r. Fig. 4B is a schematic diagram of a broken block type structure trapping a third cross-sectional area according to an embodiment of the present invention. Wherein the third cross-sectional area may be used to characterize a cross-sectional area resulting from a controlled trapping fault effect of the fault block configuration. As shown in fig. 4B, the third cross-sectional area may be expressed as 1/2 x H _r×H_r×(tanβ₁+tanβ_r). Thus, the second fault function may be denoted F＝1/2×H_r×H_r×(tanβ₁+tanβ_r)/(L_r×H_r)＝H_r(tanβ₁+tanβ_r)/2L_r. further, when β ₁＝β_r =β, the second fault function may be denoted f=h _r tanβ/L_r. And for the fault block type structure trap, after the target parameter information is obtained, substituting the second fault parameter information in the target parameter information into the second fault function, and calculating to obtain the fault correction coefficient of the fault block type structure trap.

It should be noted that the first fault function and the second fault function may be set to the same function form, or may be set to different function forms, and may be specifically set according to actual requirements. If the first fault function and the second fault function have the same function form, the first fault function and the second fault function are set as f=h _r(tanβ₁+tanβ_r)/2L_r. For a block-type construction trap, β ₁ and β _r represent the left and right wing control ring fault angles, respectively, for a block-type trap on a standard cross section, while for a back-off oblique construction trap, β ₁ represents the control ring fault angle for a back-off oblique trap on a standard cross section, where β _r is absent (neglected). In contrast, since neither β ₁ nor β _r exist in the anticline structure trap, the fault correction coefficient does not need to be considered, and thus the fault correction coefficient of the anticline structure trap can be set to 0 directly. Thus, the fault correction coefficients of the three structural traps can be respectively solved by setting a general fault function.

In the embodiment, optionally, determining the reference correction coefficient of the construction trap to be tested according to the target parameter information comprises determining the reservoir correction coefficient of the construction trap to be tested according to reservoir parameter information in the target parameter information and a preset reservoir function, wherein the reservoir parameter information comprises a reservoir dip angle in the construction trap to be tested, and the preset reservoir function is used for describing a mapping relation between the reservoir parameter information and the reservoir correction coefficient.

The reservoir parameter information may refer to parameter information associated with determining a reservoir correction coefficient in target parameter information of a construction trap to be measured. The reservoir parameter information comprises a reservoir dip angle in a construction trap to be measured. The preset reservoir function may be a preset function relationship for determining the correction coefficient of the reservoir of the construction trap to be tested, and may be used for describing the mapping relationship between the reservoir parameter information and the reservoir correction coefficient. For example, the preset reservoir function may be set to r=1/cos γ -1, where R represents the reservoir correction factor and γ represents the reservoir dip within the build trap under test.

Specifically, as shown in the right hand graph of fig. 2A-2C, the cross-sectional area of the test structure trapped at the desired angle (i.e., the second cross-sectional area) may be represented as L _r×H_r, where L _r and H _r represent the reservoir cross-sectional length and reservoir cross-sectional thickness, respectively, over the range of the test trap at the desired angle over the standard cross-section. Fig. 5 is a schematic diagram of a fourth cross-sectional area of a trap of a structure to be tested according to a first embodiment of the present invention.

Wherein the ideal state refers to a state at an ideal angle, and the fourth cross-sectional area can be used for representing the cross-sectional area of the construction trap to be tested, which is caused by the influence of reservoir occurrence inclination. As shown in fig. 5, the fourth cross-sectional area may be represented as L_rt×(H_r-L_r)×H_r＝L_r/cosγ×H_r-L_r×H_r＝L_r×H_r×(1/cosγ-1), where L _rt is the true reservoir cross-sectional length due to reservoir production dip over the range of the configuration trap to be tested. Thus, the preset reservoir function may be expressed as r=l _r×H_r×(1/cosγ-1)/(L_r×H_r) =1/cos γ -1, and by this general preset reservoir function, the fault correction coefficients of the three structural traps may be solved respectively.

In this embodiment, after determining the reference correction coefficient of the trap of the structure to be measured, the volume correction coefficient of the trap of the structure to be measured may be further determined according to the reference correction coefficient. For example, a general equation for calculating the volume correction coefficient may be set, for example, V _FA =1-C-f+r, to determine the volume correction coefficients of the three types of the construction traps to be measured respectively. Wherein V _FA is a volume correction coefficient of the structural trap to be measured, C, F and R are an amplitude correction coefficient, a fault correction coefficient and a reservoir correction coefficient of the structural trap to be measured, respectively. Specifically, for a anticline construction trap, no consideration is given to the fault correction coefficient, so that f=0, i.e. V _FA =1-c+r, and for a block construction trap no consideration is given to the amplitude correction coefficient, so that c=0, i.e. V _FA =1-f+r, can be set.

In the embodiment, optionally, the volume correction coefficient of the structure trap to be tested is determined according to the reference correction coefficient, and the method comprises the steps of determining the volume correction coefficient of the structure trap to be tested according to the amplitude correction coefficient and the reservoir correction coefficient in the reference correction coefficient when the trap type is anticline, determining the volume correction coefficient of the structure trap to be tested according to the amplitude correction coefficient, the fault correction coefficient and the reservoir correction coefficient in the reference correction coefficient when the trap type is anticline, and determining the volume correction coefficient of the structure trap to be tested according to the fault correction coefficient and the reservoir correction coefficient in the reference correction coefficient when the trap type is fault block type.

The back inclined type structure trap is influenced by the amplitude of the top surface and the reservoir stratum attitude inclination, so that the volume correction coefficient of the back inclined type structure trap can be determined according to the amplitude correction coefficient and the reservoir stratum correction coefficient, the broken back inclined type structure trap is influenced by the amplitude of the top surface, the fault control and the reservoir stratum attitude inclination, so that the volume correction coefficient of the broken back inclined type structure trap can be determined according to the amplitude correction coefficient, the fault correction coefficient and the reservoir stratum correction coefficient, and the broken block type structure trap is influenced by the fault control and the reservoir stratum attitude inclination, so that the volume correction coefficient of the broken block type structure trap can be determined according to the fault correction coefficient and the reservoir stratum correction coefficient.

In the embodiment, optionally, the volume correction coefficient of the construction trap to be detected is determined according to the amplitude correction coefficient and the reservoir correction coefficient in the reference correction coefficient, and comprises the steps of determining the volume correction coefficient of the construction trap to be detected through a first volume formula, wherein the first volume formula is expressed as V _FA =1-C+R, V _FA is the volume correction coefficient, C is the amplitude correction coefficient, R is the reservoir correction coefficient, determining the volume correction coefficient of the construction trap to be detected according to the amplitude correction coefficient, the fault correction coefficient and the reservoir correction coefficient in the reference correction coefficient, and comprises the step of determining the volume correction coefficient of the construction trap to be detected through a second volume formula, wherein F is the fault correction coefficient, and determining the volume correction coefficient of the construction trap to be detected according to the fault correction coefficient and the reservoir correction coefficient in the reference correction coefficient, wherein the third volume formula is expressed as V _FA =1-F+R.

Wherein a first volumetric formula may be used to determine the volume correction factor for a anticline configuration trap, a second volumetric formula may be used to determine the volume correction factor for a broken anticline configuration trap, and a third volumetric formula may be used to determine the volume correction factor for a broken block configuration trap. In this embodiment, when determining the volume correction coefficient of the trap of the structure to be measured, the volume correction coefficient of the trap of the structure to be measured of the corresponding trap type can be determined through simple calculation by substituting the reference correction coefficient of the corresponding trap type into the corresponding volume formula.

For example, the first volumetric formula for determining the volumetric correction factor for a anticline configuration trap may be specifically represented as V_FA＝1-C+R＝1-H_r(cotα₁+cotα_r)/2L_r+1/cosγ-1＝1/cosγ-H_r(cotα₁+cotα_r)/2L_r., where L _r and H _r are the reservoir cross-sectional length and the reservoir cross-sectional thickness, respectively, in the anticline trap range on the standard cross-section at the ideal angle, α ₁ and α _r are the left wing top surface tilt and the right wing top surface tilt, respectively, for anticline trap on the standard cross-section, and γ is the reservoir tilt in anticline trap. Further, when α ₁＝α_r =α, the first volume formula can be simplified to V _FA＝1/cosγ-H_rcotα/L_r.

For example, the second volumetric formula for determining the volume correction factor for a back-off type of construction trap may be specifically expressed as V_FA＝1-C-F+R＝1-H_r cotα/2L_r-H_r tanβ/2L_r+1/cosγ-1＝1/cosγ-H_r(cotα+tanβ)/2L_r., where L _r and H _r are the reservoir cross-sectional length and the reservoir cross-sectional thickness, respectively, over the range of the back-off type of construction trap at an ideal angle, α is the top tilt angle of the back-off type of construction trap over the standard cross-section, β is the controlled fault tilt angle of the back-off type of construction trap over the standard cross-section, and γ is the reservoir tilt angle within the back-off type of construction trap.

For example, a third volumetric formula for determining the volumetric correction factor of a fault block configuration trap may be specifically represented as V_FA＝1-F+R＝1-H_r(tanβ₁+tanβ_r)/2L_r+1/cosγ-1＝1/cosγ-H_r(tanβ₁+tanβ_r)/2L_r., where L _r and H _r are the reservoir cross-sectional length and the reservoir cross-sectional thickness, respectively, within the fault block trap range on a standard cross-section at an ideal angle, β ₁ and β _r are the left and right wing control ring fault angles, respectively, for the fault block trap on the standard cross-section, and γ is the reservoir angle within the fault block trap. Further, when β ₁＝β_r =β, the third volume formula can be reduced to V _FA＝1/cosγ-H_r tanβ/L_r.

In this embodiment, a description will be given of a process of determining the volume correction coefficient by taking a broken anticline structure trap as an example. Specifically, a standard cross section of the back-off inclined structure trap is determined according to the cross section of the target line segment in the back-off inclined structure trap range, see fig. 2B. The target line aa ' is a line segment perpendicular to the control ring fault in the back-inclined structure trap range, and the length of the target line aa ' is equal to half of the length of the third reference line segment bb '. The L _r =250m and the alpha=30deg. can be calculated according to the structural diagram of the back-cut inclined structural trap, and the H _r =50m can be inquired according to the well logging interpretation result of the adjacent wells around the back-cut inclined structural trap. Wherein L _r and H _r respectively represent the reservoir cross-sectional length and the reservoir cross-sectional thickness within the range of the back-off-diagonal trap on the standard cross-section at the ideal angle, and α is the top surface tilt angle of the back-off-diagonal trap on the standard cross-section, see fig. 2B and 3B. At this time, the amplitude correction coefficient of the back-off oblique structure trap can be determined to be c=h _r cotα/2L_r =50 m×cot30 °/(2×250m) =0.173 from the second amplitude function. By querying the seismic section of the back-cut inclined structure trap, beta=35°, wherein beta is the inclination angle of the control circle fault of the back-cut inclined structure trap on the standard cross section, and particularly, see fig. 4A. At this time, the tomographic correction factor of the back-off oblique structure trap can be determined from the first tomographic function to be f=h _r tanβ/2L_r =50m×tan 35 °/(2×250 m) =0.070. By querying the seismic section of the back-off inclined structure trap, γ=10° can be calculated, wherein γ is the reservoir dip angle in the back-off inclined structure trap, and particularly, refer to fig. 5. At this time, according to the preset reservoir function, it can be determined that the reservoir correction coefficient of the back-off inclined structure trap is r=1/cos γ -1=1/cos 10 ° -1=0.015. Thus, the volume correction coefficient of the back-off oblique construction trap can be obtained according to the second volume formula as V _FA =1-C-f+r=1-0.173-0.070+0.015=0.772.
