Packer 6 is made of hydraulic, mechanical or electrical action.

A pump installation for simultaneous and separate operation of wells (Option 1) works as follows.

According to figure 1, a sucker-rod deep-well pump 2 with a monolithic liner 3 is lowered to a predetermined depth into a well on a tubing 1 with a hydraulic channel 4, on which a packer 6 with a regulating shut-off-by-pass device 7 is located. Next, a packer 6 is packaged between the perforation intervals 20 and 21.

The hydraulically adjustable packer 6 is in a sealed state, while the fluid from the lower reservoir passes through the regulating shut-off / bypass device 7, which is installed in the seat of the packer 6. In this case, the fluid enters the sucker rod pump 2 through the lateral bypass hole 9 in the liner 3.

A hydraulically adjusting locking-overflow device 7, installed in the packer 6, regulates the communication or disconnection of the lower interval of the perforation 21 with the over-packer region - with the upper interval of the perforation 20.

After actuating the sucker rod pump 2 into operation, two formations are simultaneously involved in the development with perforation intervals of 20 and 21.

To disconnect from the development of the lower interval of perforation 21, a fluid is pumped from the surface into the hydraulic channel 4 at a pressure sufficient to actuate the hydraulic shut-off device 7. If necessary, the joint operation of two layers reduces the pressure in the shut-off device 7, which leads to its opening and fluid intake to receive the pump from the lower reservoir at the same time as the fluid from the upper reservoir.

In Fig. 2, in contrast to Fig. 1, a pumping unit for simultaneous and separate operation includes two hydraulic channels 4, which supply hydraulic pressure to the regulating shut-off-by-pass devices 7 installed in the shank 3. After the packer 6 is lowered and packaged, the rod the deep pump 2 is put into operation and at the same time two formations are involved in the development with perforation intervals of 20 and 21.

To disconnect from the development of one of the perforation intervals 20 or 21 from the surface, liquid is injected into a predetermined umbilical 4 or both umbilicals 4 under a predetermined pressure to actuate the hydraulic control shut-off / bypass device 7.

Changing the pressure in the hydrochannel 4 and, accordingly, in the regulating shut-off and bypass devices 7, achieve the desired operating mode of the proposed pump installation.

Periodic alternate shutdown of one of the strata with perforation intervals of 20 or 21 allows direct measurements of the composition and water cut of the produced fluid separately for the strata.

Figure 3 presents the proposed pump installation with a sucker rod pump 2 having an additional side valve 22. In this case, in the channel connecting it to the chamber of the lower suction plunger, a regulating shut-off-by-pass device is installed 7. After the pumping unit is lowered and the packer 6 is packaged at a given depth, a sucker rod pump 2 is started up, which begins to take fluid from the intervals of perforations 20 and 21. If it is necessary to turn off the upper formation with an interval of perforation 20, they are pumped into hydraulic channel 4 under pressure for remotely transferring the control shut-off device 7 to the mode of closing the communication of the side suction valve 22 with the sucker-rod pump 2. After that, only from the lower reservoir with a perforation interval 21 is produced fluid with sampling to determine its composition and water cut. This pumping unit is used in cases of excess pressure of the upper reservoir over the lower reservoir.

If the pressure of the upper reservoir with an interval of perforation 20 is less than the pressure of the lower reservoir with an interval of perforation 21, then use the installation shown in figure 4, which presents the proposed pump installation also with a side suction valve 22 with the function of a regulating shut-off device 7. However, through fluid from the lower reservoir is sucked in with a perforation interval 21 with a higher pressure. In this case, the shank 3 is additionally equipped with a bypass pipe 23 connecting the side suction valve 22 with the under-packer region (Fig. 4). The second control shut-off-bypass device 7 is located in the shank 3 for regulating and cutting off the flow of fluid from the upper reservoir with an interval of perforation 20.

After actuating the plunger of the sucker rod pump 2, two reservoirs are simultaneously brought into operation with perforation intervals 20 and 21. At the same time, fluid from the lower reservoir with a perforation interval 21 with a high pressure from the packer 6 along the shank 3 enters through the side suction valve 22 then from the shank 3 through the bypass pipe 23 to the side suction valve 22.

To disconnect from the development of one of the perforation intervals 20 or 21 from the surface, liquid is injected into the hydrochannel 4 at a predetermined pressure to close the hydraulically regulating side suction valve 22 or the regulating shut-off / bypass device 7.

Changing the pressure in the hydrochannel 4 and, accordingly, in the side suction valve 22 or regulating shut-off and bypass device 7, achieve the specified operating mode of the proposed pump installation.

Periodic shutdown of a given formation with a perforation interval of 20 or 21 provides the ability to make direct measurements of the composition and water cut of the produced fluid together or separately for one of the layers.

Pump installation for simultaneous and separate operation of wells according to option 1, shown in Fig.5 and Fig.6, works as follows.

On the tubing 1, a “hanging” packer 6 is lowered, for example, of a hydraulic type with a lower funnel 24, equipped with a column disconnector 17 on top, installed in a production string 25 in a predetermined interval between the perforation intervals 20 and 21, and the tubing 1 is disconnected and lifted to the surface ( figure 5).

After that, in the base of the shank 3 set the rod of the disconnector of the columns 17 for fixing with the housing of the disconnector of the columns 17 and the packer 6.

Then, an electric pump 2 with a liner 3 is lowered onto the tubing 1, on which a centralizer 18 and a remote-controlled well chamber 8 with a regulating shut-off-by-pass device 7 in the form of a regulator are installed, a hydraulic channel 4 connected to the regulator 7, from the bottom of which the column disconnector rod 17 s is installed centralizer 18. During the descent, the rod of the disconnector of the columns 17 is hermetically installed in the housing of the disconnector 17 with the specified unloading on the previously installed packer 6 (Fig.6).

Next, a submersible motor 10 is driven, which drives the electric pump 2.

The formation fluid from the lower interval of perforation 21 begins to flow into the funnel 24, then into the borehole chamber 8 with the regulator 7 and through the regulator 7 into the overpacker region, then into the receiving grid 15. After that, the electric fluid 2 rises to the surface by the electric pump 2. At the same time, the formation fluid from the upper formation from the perforation interval 20 also enters through the receiving grid 15 to receive the electric pump 2 and then to the surface.

To exclude from the development of the lower reservoir with a perforation interval 21, pressure is supplied to the hydraulic channel 4 and, due to the remote transmission of excess pressure, the remote-controlled hydraulic regulator 7 is closed, which leads to blocking the inflow from the perforation interval 21.

By periodically changing the pressure in the hydraulic channel 4, the regulator 7 is periodically opened or closed, due to which the flow of fluid from the lower reservoir is regulated with an interval of perforation 21 for receiving the electric pump 2.

According to Fig. 7, tubing 1 is first lowered into production casing 25 and packer 6 is installed, then tubing 1 is already lowered again with power cable 5 and hydraulic channel 4 to a predetermined depth, ESP pump 2 with hollow shank 3, equipped with holes 9 and made in the form perforated coupling.

On the hollow shaft 3 there are two packers 6, two regulating shut-off and bypass devices 7 in the form of two remotely controlled well chambers 8 with regulators 7. The hollow shaft 3 is equipped with a plug 26. The disconnector of the column 17 is located on the shaft 3 above the sealed packer 6.

The electric pump 2 is started, the formation fluid is started from the upper perforation interval 20 and from the lower perforation interval 21. Moreover, the regulators 7 are hydraulically regulating fittings with passage holes and are in the “open” position.

The packer 6 is hermetically uncoupled the perforation intervals 20 and 21. Using the regulators 7, separate regulation of the inflows of the formation fluid from each formation is carried out with an interval of perforation 20 and 21. The formation fluid is transferred to the intake of the electric pump 2 through the side bypass hole 9 in the shank 3.

To disconnect from the development of one of the perforation intervals 20 or 21 from the surface, a fluid is pumped into the hydraulic channel 4 at a pressure sufficient to actuate the hydraulic regulator 7, and / or electricity is supplied to the electromechanical regulator 7 to operate it.

If it is necessary to select formation fluid only from the lower reservoir with an interval of perforation 21, the passage hole in the upper regulator 7 is closed by supplying a predetermined pressure to the hydraulic channel 4, sufficient to close the upper regulator 7.

Regulators 7 are configured for multi-positioning, that is, to the “closed”, “open”, “partially open” position, at different hydraulic pressures or in antiphase pressures, or a separate hydraulic channel 4 is brought to each regulator 7. In this case, the state of regulator 7 is controlled remotely hydraulically or electrically, which allows the installation of the regulator 7 in predetermined various multi-position open positions of the plugged hole with the choice of the optimal inflow mode from each layer with a perforation interval of 20 21 and provide simultaneous and separate operation of two layers.

On the tubing 1 with two hydraulic channels 4 in one umbilical, a sucker rod pump 2 with a shank 3 is lowered to a predetermined depth, on which are two control shut-off-by-pass devices 7 in the form of two remotely controlled borehole chambers 8 with regulators 7 and two packers 6 installed at the end of the descent with hermetically cutting off from each other the perforation intervals 20 and 21. The column disconnector 17 is located above the lower packer 6 or between the packers 6 (Fig. 8).

The lower packer 6 is mechanically packaged by rotating or axial movement, and the upper packer 6 is packaged by pressing and unloading the lower packer 6.

At the base of the shank 3, control and measuring research devices 11 with a communication cable 19 are installed to obtain data on the properties of the fluid, flow rate and water cut and other parameters with their transmission over the communication cable 19 to the surface.

After actuating the plunger of the sucker rod pump 2, two layers are simultaneously involved in operation with perforation intervals 20 and 21.

To disconnect from the development of one of the perforation intervals (20 or 21), liquid is injected from the surface into the umbilical 4 with a predetermined pressure sufficient to close or open the hydraulically controlled control shut-off and bypass devices 7.

By changing the pressure in one of the hydraulic channels 4 and, accordingly, in the regulating shut-off-by-pass devices 7, the desired operating mode of the proposed pump installation is achieved. Periodic shutdown of a given formation with a perforation interval of 20 or 21 allows you to make direct measurements of the composition and water cut of the produced fluid together or separately for one of the layers.

With simultaneous and separate development of three reservoirs with the possibility of conducting direct measurements of flow rates separately for the reservoirs with sampling to determine water cut and other fluid parameters, in combination with remote methods for exploring the well, the proposed pumping unit shown in Fig. 9 is used.

A packer 6 with a column disconnector 17 and a funnel 24 is lowered and installed into the well. Then, an electric pump 2 with an electric power cable 5 supplying the electric motor 10 and a hydraulic channel 4 in the form of a umbilical to a predetermined depth are lowered on a pipe string 1. In this case, the electric pump 2 includes a receiving grid 15, a centralizer 18, a disperser 14 and a gas separator 16 and is made with a shank 3 having a bypass hole 9 in the upper part and a hydraulically controlled over-packer valve is used in the lower part as a regulating shut-off / bypass device (Fig. .9).

On the shank 3 there are two packers 6 and two control shut-off and bypass devices 7 in the form of two remotely controlled well chambers 8 with regulators 7. Under the packers 6 on the tubing 1 with a hydraulically controlled valve 7, additional cable research measuring and measuring devices 11 and autonomous monitoring devices are installed -measurement devices 11. Above the electric pump 2 there is an upper packer 6 for cutting off, for example, from the overlying leakage interval 127 and an ejector 13 for pumping free gas from under the packer 6.

After applying voltage to the electric cable 5, the engine 10 starts, which drives the gas separator 16, dispersant 14, electric centrifugal pump 2 and ejector 13. Due to the lifting of the fluid by the electric centrifugal pump 2 to the surface, three layers are simultaneously involved in the development with perforation intervals 28, 20, 21. At the same time, the upper packer 6 will cut off the overlying leakage interval 27 from the development. During operation, studies are carried out in the well using cable instrumentation 11, incl. measuring flowmeters (resistivimeters, moisture meters, manometers, etc.), with the transmission of information through the communication cable 19. Autonomous instrumentation 11 are installed at anchors 29 or in borehole chambers 8. Autonomous instrumentation 11 determine volumes, water cut and other parameters incoming fluids separately for the strata.

When disconnecting from the development of the lower interval of perforation 21 from the surface, liquid is injected into the hydraulic channel 4 at a predetermined pressure to regulate a hydraulically controlled shut-off and by-pass valve 7 and two perforation intervals 20, 28 are operated simultaneously with the determination of direct measurements at the mouth of the water cut and other parameters produced fluid. Using research instruments 11 located on the shank 3, determine the volume of inflows from the intervals of perforation 20, 28.

During the operation of the well using a hydraulic channel 4 and through two control shut-off and bypass devices 7, namely, regulators and a hydraulically controlled valve, they alternate periodically shut off working intervals from the joint development, as well as regulate inflows from them. In combination with the use of research instrumentation 11 and the possibility of direct measurements of the parameters of the produced fluid at the wellhead, they carry out comprehensive control and accounting of the produced products (oil) in the well.

A pump installation for simultaneous and separate operation of wells with an electric packer, instrumentation works as follows (figure 10).

An electric centrifugal pump 2 with a shank 3 and a power electric cable 5, an electric packer 6 with a hydraulically regulating shut-off and bypass device 7 with a hydraulic channel 4 and control and measuring cable devices 11 are launched onto the tubing 1. An electric packer 6 is installed in a predetermined interval of the production string 25 above the electric centrifugal pump 2. On the shank 3 are instrumentation 11 on the cable for communication 19 in limbo. The electric power cable 5 supplies current to the electric motor 10 and starts the electric centrifugal pump 2. Formation fluid from three layers with perforation intervals 28, 21, 20 enters through the receiving grid 15, the separator 16 and dispersant 14 into the electric centrifugal pump 2 and then rises through the tubing 1 to the surface. In this case, the fluids from the intervals of the perforations 28, 21, 20 pass through the control and measuring devices 11.

The operating mode of the control shut-off and bypass device 7 is remotely set by the technical conditions of the proposed pump installation, for example, for bypassing gas from under the packer 6 or for bypassing the overpacker fluid to receive an electric centrifugal pump 2.

Example 1. In a well on a tubing 1 with a hydraulic channel 4, a sucker rod pump 2 with a monolithic liner 3 is lowered to a predetermined depth, on which a packer 6 and a regulating shut-off-by-pass device 7 are located.
