Description
Technical field
Shallow sea oil-gas exploration and exploitation.
Background technology
Oil-gas geology, exploration strategy, development and Design.
Summary of the invention
The typical oil-gas reservoir in basin, Bohai Sea Gulf is that compound oil gas complicated and changeable is hidden.Fault block is many, and the stratum cross directional variations is big, and oil-gas Layer is many.The expert to its complexity vividly describe for " neglect oil neglect water, up and down, neglect thick approach suddenly, neglect thick rare suddenly, suddenly appear and disappear." and " plate of smashing has been kicked a pin again ".The Bohai Sea oil-gas exploration and development model of integration (the abbreviation model of integration) is exactly a kind of brand-new exploration and development pattern to the invention of shallow water rich oil gas basin complex reservoir.
Bohai Sea oil-gas exploration and development normal mode (abbreviation normal mode) branch is explored, designs, builds and is developed 4 stages at present.Exploration phase is confirmed the scale and the character of oil gas field through prospect pit and evaluation well.Design stage is estimated oil-gas reservoir according to the exploration result, and designs the ODP scheme of oil-gas field development according to evaluation result.Construction phase is built development platform, FPSO ship and other fixture according to the ODP scheme.Development phase, development devices such as carrying, installation, debug platform bore development well, produce hydrocarbons.Each stage all studied the result in great detail according to the last stage and formulates and implements scheme and construct, and was a kind of safe formula of cutting the garment according to the figure exploration and development normal mode.The model of integration and normal mode have 2 different, the first, from exploring directly to exploitation middle not design and construction phase; The second, exploration and development is carried out continuously, and is middle at interval not free; Be a kind of from exploring the hypervelocity exploration and development pattern that the operation this season is accomplished.The model of integration is constructed as follows:
1)
[0005]The laying work area line.
Lay two regional lines.Line from east to west from Tanggu to the PL19-3 oil field.Meridian line from the Liaohe River mouth through PL19-3 oil field to the Weihe River mouth.Oil-gas pipeline, submarine cable and submarine optical fiber cable are laid simultaneously.Every petroleum pipeline year oil transportation ability 1,000 ten thousand sides.1,000,000 kilowatts of cable power transmission abilities.The optical cable capacity will arrive base, Tanggu greatly can omnidistance monitoring and the production of 1000 platforms of remote control.
2) exploitation standard platform
With the oil-gas field development device of present routine from new combination, development and Design 3 kinds of miniaturization standard developments platform and L ship.Satisfy different scales with number change, change with type and satisfy different work, make standard platform can develop all off-gauge complex hydrocarbon fields.
The C platform is unmanned production platform, and the long-term device and the very little dingus that takes up room that uses is installed.The J platform is interim job platform, the apparatus for work that erection stage uses.The Z platform is the center production platform, be responsible for to handle and carry near the oil gas of a plurality of production platforms, and, production of hydrocarbons transport, production platform remote control and personnel's lifestyle device are installed to the remote control and the tour of production platform.The L ship is the FPSO of a miniaturization basically, pipeline repair logical before responsible oil interim production, preserve and transport task.
3) the extra large Buddha's warrior attendant of exploitation distortion (seeing the extra large Buddha's warrior attendant patent of distortion for details, application number 2011100071501)
Being out of shape extra large Buddha's warrior attendant is the omnipotent whole carry vessel of any weight of a kind of integral demounting, carrying and installation, center, size and shape.Dismounting, carrying and the installation of Bohai Sea all types platform are accomplished by it.
4) progressive exploratioon and development.
To disperse single-point exploration, become that pipeline is arranged is the concentrated exploration that relies on.Rely on pipeline progressively to extend exploration and development.Along with the oil-gas field development pipeline extends into net gradually.
5) integrated exploration and development.
In the past Bohai Sea Gulf from explore to develop get step by step very clear.The exploration phase well (exploration well that is equivalent to land) of prying into; Evaluation phase is beaten evaluation well (being equivalent to the land prospect pit); Development and Design stage design development plan with design and develop platform (write ODP report), the exploitation preparatory stage makes, mounting platform, the development phase is beaten development well.And integrated exploration is exactly from exploration---develop each stage and carry out continuously, once accomplish.
The model of integration is named drilling well is unified according to the land standard.Exploration well, prospect pit, evaluation well and producing well.Exploration well---be equivalent to the prospect pit of normal mode, first mouthful of well of trap is in order to explore HC potential of traps.Prospect pit---be equivalent to the evaluation well of normal mode, first mouthful of well of fault block (or lithologic body) is in order to explore its oil-gas possibility.Evaluation well---confirm the well of oil and gas reserves; And normal mode is calculated according to data such as prospect pit reservoir pressures, does not bore evaluation well, and certain uncertainty is arranged.The well of producing well---produce hydrocarbons, exploration well, prospect pit and evaluation well can become producing well, and the above-mentioned well of normal mode is generally all discarded.
The exploration well well location is confirmed method: select maximum in the trap, fault block or lithologic body that petroleum-geologic condition is best are at first drilled.Well is worn the multilayer trap as far as possible, particularly the main purpose layer.Usually should be directional well like the fault block exploration well, press close to tomography and bore high point.The oil gas of this fault block is as far as possible all disclosed.Normal mode moves down into the exploiting economy thresholding of expection with well location, and exploration well, evaluation well unite two into one.
The prospect pit well location is confirmed method: prospect pit is consistent with the exploration well purpose to be the well of exploring oil-gas possibility, so well location is confirmed the method unanimity, wears the multilayer trap as far as possible.Should press close to tomography like the fault block prospect pit and bore high point.Normal mode moves down into the exploiting economy thresholding of expection with well location, and prospect pit, evaluation well unite two into one.
The evaluation well well location is confirmed method: the economy of confirming reserves and exploitation.At first bore the M evaluation well, whether the pipe network expense is disregarded in spy has economy.If success, and then bore the D evaluation well, whether visit meter pipe network expense has the stand-alone development economy.Fault block is disregarded the pipe network expense has exploitation to be worth, and calculates pipe network and take not that exploitation is worth, and might add that other fault block just has exploitation value.A fault block is disregarded all not exploitation value of pipe network expense, and then it does not develop value.If the fixed position of evaluation well is low excessively, subdrilling D evaluation well just might be missed the possibility of joint development.
Integrated exploration and development method: at first each fault block of complicated trap is ranked, to confirm the probing order.Drill ship band C platform is explored.If exploration well finds that oil-gas reservoir is too little, then stop the exploration of this structure.If discovery oil-gas reservoir, and the worth M evaluation well that bores of well log interpretation affirmation, offshore boring island does not move, and then bores the M evaluation well.If it is littler than estimating that M evaluation well well log interpretation is confirmed reserves, disregarding the pipe network expense does not have economy yet, then stops this structure exploration.There is stand-alone development to be worth if might calculate the pipe network expense, then then bores the D evaluation well immediately.Transfer the L ship that exploration well and M evaluation well are test-manufactured simultaneously.If probing of D evaluation well as expection then continue the probing end hole, and according to the delineation well result, bore producing well immediately.With C platform+L ship fault block 1 is developed.Just accomplish to producing in 3 months from sondage like this.
Do not have stand-alone development to be worth if D evaluation well results of drilling is calculated the pipe network expense, then bore fault block 2 with same flow process.Have exploitation value if fault block 1+ fault block 2 is united, then platform is motionless, develops fault block 2 immediately.Go back to exploitation fault block 1 then.
Also do not have exploitation value if fault block 1+ fault block 2 is united, then bore fault block 3 with same flow process.Have exploitation value if fault block 1+ fault block 2 is united, then platform is motionless, develops fault block 3 immediately.Go back to exploitation fault block 1 and fault block 2 then.Also do not have exploitation value if fault block 1+ fault block 2+ fault block 3 is united, then stop exploration.Make a decision again after waiting to study.
6) decisive battle
In case the exploration situation is very good, musters all one's strength immediately and carries out decisive strategic engagement.At first concentrate this structural belt of drill ship to carry out integrated exploration, the platform of drawing on stock simultaneously.If the exploration situation is terribly good, even can the drill ship in other marine site all be transferred.At this moment stock's platform is not enough certainly, can temporary close near the production platform of some relative low yields, it is moved, at first satisfy the decisive battle needs.Later on progressively recover the temporary close production platform with the platform of new production again.Elephant begins to take shape from the sondage to production so only needs 1 year.
7) oil gas is failed, stores up, is transported
Oil gas is all carried by pipeline.FPSO and land terminal with marine elephant are done the oil movement and storage center.Each 1-2 FPSO in Bo Xi, Liaodong Wan, Laizhou Wan, the Bohai Sea.The PL19-1 oil field all at center, marine site separately, is fit to do the accumulating center in CFD11-1 oil field, Bohai Sea west, Liaodong Wan SZ36-1 oil field, Laizhou Wan BZ28-1 oil field, the Bohai Sea.The oil in all oil fields all is transported to the accumulating center, concentrates outwards transportation again.Natural gas is concentrated last three land terminals.Terminal, the west of Liaoning on the Liaodong Wan, terminal, Tanggu is gone up with Bo Xi in the Bohai Sea in terminal, Longkou on the Laizhou Wan.Other oil gas field is not being used FPSO, does not only repair as yet at pipeline and temporarily uses the L ship when leading to.
