Description

Technical Field

[0001] The invention belongs to the technical field of oil and natural gas drilling and completion, and particularly relates to an integrated control module and a production sliding sleeve. Background Art

[0002] At present, the remote control technology of downhole intelligent tools is relatively mature and has been widely used. For example, multi-layer intelligent injection or production strings use two types of intelligent downhole tools: liquid-controlled and electronically controlled.

[0003] Existing hydraulically controlled intelligent injection and production tools use n+1 hydraulic control pipelines to control n layers of hydraulic control sleeves to achieve shift switch operations, where n is a positive integer greater than or equal to 1. When performing multi-layer injection or production, the excessive number of hydraulic control pipelines often leads to the lowering of multiple hydraulic control tools into multiple pipelines, resulting in a sharp increase in construction risks, which directly increases operating costs and reduces operation time.

[0004] Although electronically controlled intelligent injection and production tools use a single control cable to control the switch of each layer section tool, there are some defects in the switch control. For example, the axial driving force of the micro motor is relatively small. If the tool is scaled or oily, the sliding parts in the tool are prone to getting stuck, causing the switch to fail.

[0005] To this end, electro-hydraulic hybrid and electric-controlled hydraulic-driven downhole intelligent tools have emerged. Existing electro-hydraulic hybrid downhole flow control tools use two hydraulic control lines and one cable. While this tool reduces the number of hydraulic control lines, it still suffers from the problem of lengthy hydraulic transmission times over long distances due to friction in the hydraulic control lines. Furthermore, the tool's operation relies on two ground-based control devices, resulting in complex control methods and supporting equipment. One electronic control device uses different logical relationships to control the operation of downhole solenoid valves in different layers to switch hydraulic channels, while the other hydraulic control device controls the tool's on / off function via two hydraulic control lines.

[0006] In addition, for downhole flow control tools of the electrically controlled hydraulic drive type, the hydraulic drive generally adopts a traditional mechanical structure. The setting of downhole packers is achieved by applying pressure inside the tubing to drive the piston cavity to compress the sealing rubber cylinder and the anchoring slips, and the release also adopts a similar hydraulic method. Cable setting tools often use the method of lowering the cable + igniting the gunpowder to use hydraulic drive to achieve the setting and release of the packer. The action time is short and it is very easy to cause instability in the setting. Downhole safety valves generally use hydraulic pipelines to pressurize the internal center pipe to move axially to achieve the opening and closing of the safety valve plate. At present, the above-mentioned commonly used hydraulically driven downhole tools do not have the ability of remote intelligent operation, and cannot meet the use requirements of the existing smart oilfield full-wellbore intelligent production tools.

[0007] In the field of drilling and completion, there are currently no downhole tools or similar structures that use electric-controlled hydraulic drive with their own pressure source. The more mature technology is still the electric-controlled and hydraulic-controlled downhole remote control technology, that is, the downhole tool is activated and its operation is controlled through cables or hydraulic pipelines. At present, intelligent downhole tools do not have an integrated method to integrate hydraulic components such as motors, micro pressure pumps, check valves, solenoid valves, and relief valves into a small valve body.

[0047] like Figure 1 、 Figure 2 and Figure 3As shown, an integrated control module 00 according to an embodiment of the present invention is shown, which includes an execution unit 02 and a hydraulic pump 011 system 01 disposed in an oil storage chamber 07 of a downhole tool. The hydraulic pump 011 system 01 and the execution unit 02 are both connected to a control unit. The control unit is used to control the execution unit 02 to be in a first state, a second state, or a third state. When the execution unit 02 is in the first state, the hydraulic pump 011 system 01 can pump the hydraulic oil in the oil storage chamber 07 to the first piston chamber 03 of the downhole tool through the execution unit 02. And the hydraulic oil in the second piston chamber 04 of the downhole tool can flow back to the oil storage chamber 07 through the execution unit 02; when the execution unit 02 is in the second state, the hydraulic pump 011 system 01 can pump the hydraulic oil in the oil storage chamber 07 to the second piston chamber 04 of the downhole tool through the execution unit 02, and the hydraulic oil in the first piston chamber 03 of the downhole tool can flow back to the oil storage chamber 07 through the execution unit 02; when the execution unit 02 is in the third state, the hydraulic pump 011 system 01 cannot pump the hydraulic oil in the oil storage chamber 07 to the first piston chamber 03 and the second piston chamber 04 of the downhole tool through the execution unit 02.

[0048] Specifically, the integrated control module 00 of this embodiment is arranged in the oil storage chamber 07 of the downhole tool. The integrated control module 00 includes an execution unit 02 and a hydraulic pump 011 system 01. The execution unit 02 and the hydraulic pump 011 system 01 are both controlled by a control unit. The control unit is connected to the ground control system through a control cable 1, and the ground control system supplies power to the control unit and realizes control data communication between the control unit and the ground control system. Therefore, compared with the prior art, the embodiment of the present invention only requires one control cable 1 to control the downhole tool.

[0049] With respect to the execution unit 02, it has a first state, a second state and a third state: when it is in the first state, the hydraulic pump 011 system 01 can pump the hydraulic oil in the oil storage chamber 07 to the first piston chamber 03 of the downhole tool through the execution unit 02, and the hydraulic oil in the second piston chamber 04 of the downhole tool can flow back to the oil storage chamber 07 through the execution unit 02, thereby achieving the purpose of pressurizing the first piston chamber 03 of the downhole tool; when it is in the second state, the hydraulic pump 011 system 01 can pump the hydraulic oil in the oil storage chamber 07 to the second piston chamber 04 of the downhole tool through the execution unit 02, and the hydraulic oil in the first piston chamber 03 of the downhole tool can flow back to the oil storage chamber 07 through the execution unit 02, thereby achieving the purpose of pressurizing the second piston chamber 04 of the downhole tool; when it is in the third state, the hydraulic pump 011 system 01 cannot pump the hydraulic oil in the oil storage chamber 07 to the first piston chamber 03 and the second piston chamber of the downhole tool, thereby achieving the purpose of keeping the downhole tool in its current state.

[0050] Therefore, the embodiment of the present invention achieves the purpose of remotely controlling downhole tools through a control cable 1, reduces offshore operation costs, and improves operation efficiency; the downhole tools of the embodiment of the present invention are downhole intelligent flow control valves, intelligent production sleeves, water distributors or production distributors, electrically controlled sealing tools, electric packers, electric downhole safety valves, etc., so the integrated control module 00 of the embodiment of the present invention has the advantage of a wide range of applications.

[0051] In one embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, the execution unit 02 includes a first, second, and third normally closed solenoid valve 021 and a second, second, third normally closed solenoid valve 022. The first external port of the first, second, third normally closed solenoid valve 021 is connected to the first piston chamber 03 of the downhole tool, and the first external port of the second, second, third normally closed solenoid valve 022 is connected to the second piston chamber 04 of the downhole tool. The second external port of the first, second, third normally closed solenoid valve 021 and the second external port of the second, second, third normally closed solenoid valve 022 are both connected to the oil outlet of the hydraulic pump 011 system 01. The third external port of valve 021 and the third external port of the second two-position three-dimensional normally closed solenoid valve 022 are both connected to the oil storage chamber 07; when the execution unit 02 is in the first state, the first two-position three-dimensional normally closed solenoid valve 021 is powered on, and the second two-position three-dimensional normally closed solenoid valve 022 is powered off; when the execution unit 02 is in the second state, the first two-position three-dimensional normally closed solenoid valve 021 is powered off, and the second two-position three-dimensional normally closed solenoid valve 022 is powered on; when the execution unit 02 is in the third state, the first two-position three-dimensional normally closed solenoid valve 021 and the second two-position three-dimensional normally closed solenoid valve 022 are both powered off.

[0052] Specifically, the execution unit 02 includes a first two-position three-way normally closed solenoid valve 021 and a second two-position three-way normally closed solenoid valve 022. When the execution unit 02 is in the first state, such as Figure 3 As shown, the first external port (C port) of the first two-position three-dimensional normally closed solenoid valve 021 is connected to the second external port (P port) of the first two-position three-dimensional normally closed solenoid valve 021, and the first external port (C port) of the second two-position three-dimensional normally closed solenoid valve 022 is connected to the third external port (R port) of the second two-position three-dimensional normally closed solenoid valve 022. At this time, the control unit controls the hydraulic pump 011 system 01 to pump the hydraulic oil in the oil storage chamber 07 to the first piston chamber 03 of the downhole tool through the first two-position three-dimensional normally closed solenoid valve 021. The pressure in the first piston chamber 03 of the downhole tool increases, pushing the internal piston thereof to squeeze the second piston chamber 04 of the downhole tool to move, and the hydraulic oil in the second piston chamber 04 of the downhole tool flows back to the oil storage chamber 07 through the second two-position three-dimensional normally closed solenoid valve 022.

[0053] When the execution unit 02 is in the second state, Figure 2As shown, the first external port (C port) of the first two-position three-dimensional normally closed solenoid valve 021 is connected to the third external port (R port) of the first two-position three-dimensional normally closed solenoid valve 021, and the first external port (C port) of the second two-position three-dimensional normally closed solenoid valve 022 is connected to the second external port (P port) of the second two-position three-dimensional normally closed solenoid valve 022. At this time, the control unit controls the hydraulic pump 011 system 01 to pump the hydraulic oil in the oil storage chamber 07 to the second piston chamber 04 of the downhole tool through the second two-position three-dimensional normally closed solenoid valve 022. The pressure in the second piston chamber 04 of the downhole tool increases, pushing the internal piston to squeeze the first piston chamber 03 of the downhole tool to move, and the hydraulic oil in the first piston chamber 03 of the downhole tool flows back to the oil storage chamber 07 through the second two-position three-dimensional normally closed solenoid valve 022.

[0054] When the execution unit 02 is in the third state, Figure 1 As shown, there is no flow of hydraulic oil at this time.

[0055] Again, as Figure 11 、 Figure 14 As shown, the integrated control module 00 of the embodiment of the present invention also includes an integrated control valve body 0012 fixedly installed inside the oil storage chamber 07, and a first solenoid valve mounting hole 001202 and a second solenoid valve mounting hole 001203 are opened at one end of the integrated control valve body 0012, the first two-position three-way normally closed solenoid valve 021 is installed in the first solenoid valve mounting hole 001202, and the second two-position three-way normally closed solenoid valve 022 is installed in the second solenoid valve mounting hole 001203.

[0056] Specifically, the first solenoid valve mounting hole 001202 and the second solenoid valve mounting hole 001203 have the same structure, which are the first straight hole section, the sealing hole section and the second straight hole section in sequence. The first straight hole section is used to install the corresponding first two-position three-way normally closed solenoid valve 021 and the second two-position three-way normally closed solenoid valve 022; the sealing hole section cooperates with the solenoid valve stem seal to form a seal; the second straight hole section is a pressure transmission channel, with a stepped oil return hole or a straight hole in the middle for the fluid of the corresponding solenoid valve R port to return to the oil storage chamber 07; the surface of the integrated control valve body 0012 has an L-shaped groove surface, and on one side of the groove surface there are respectively a first pressure transmission process hole and a second pressure transmission process hole, the first pressure transmission process hole and the second pressure transmission process hole have the same structure, and the two are used to connect the pressure input hole or output hole, that is, the C port and P port of the corresponding solenoid valve are connected to form a coherent high-pressure fluid flow channel; sealing plugs 0016 are installed at the ends of the two pressure transmission process holes as needed to achieve pressure sealing.

[0057] In one embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, the integrated control module 00 of the embodiment of the present invention also includes a relief valve 06 and a pressure differential sensor 05. The second external port of the first two-position three-dimensional normally closed solenoid valve 021 and the second external port of the second two-position three-dimensional normally closed solenoid valve 022 are both connected to the inlet of the relief valve 06, and the outlet of the relief valve 06 is connected to the oil storage chamber 07; the second external port of the first two-position three-dimensional normally closed solenoid valve 021 and the second external port of the second two-position three-dimensional normally closed solenoid valve 022 are both connected to one end of the pressure differential sensor 05, and the other end of the pressure differential sensor 05 is connected to the oil storage chamber 07.

[0058] The pressure difference sensor 05 of this embodiment is used to detect the pressure difference between the hydraulic oil in the high-pressure pipeline and the hydraulic oil in the oil storage chamber 07, so as to determine whether the piston between the second piston chamber 04 of the downhole tool and the first piston chamber 03 of the downhole tool has moved to the limit position. Figure 2 Taking the leftward movement of the piston between the second piston chamber 04 and the first piston chamber 03 of the downhole tool as an example, after the piston moves to the left limit position, as the hydraulic oil is continuously pumped in, the piston cannot move. When the pressure difference detected by the pressure difference sensor 05 reaches the set value, the control unit first closes the first two-position three-dimensional normally closed solenoid valve 021 and the second two-position three-dimensional normally closed solenoid valve 022, and at the same time turns off the electric motor 014 to prevent the hydraulic components from being damaged by high pressure.

[0059] In this embodiment, when the pressure exceeds the set value, the relief valve 06 will open to allow the fluid in the high-pressure pipeline to flow back to the oil storage chamber 07 through the relief valve 06. That is, the relief valve 06 in this embodiment is used to protect the safety of the entire hydraulic system.

[0060] Among them, such as Figure 15 As shown, the other end of the integrated control valve body 0012 is provided with a relief valve mounting hole 001204 and a pressure differential sensor mounting hole 001206.

[0062] In one embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, the integrated control module 00 of the embodiment of the present invention also includes a one-way valve 013 and a filter device 012. The second external port of the first two-position three-way normally closed solenoid valve 021 and the second external port of the second two-position three-way normally closed solenoid valve 022 are both connected to the outlet of the one-way valve 013, the inlet of the one-way valve 013 is connected to one side of the filter device 012, and the other side of the filter device 012 is connected to the oil outlet of the hydraulic pump 011 system 01.

[0063] The filter device 012 is used to filter the oil in the oil storage chamber 07, and the one-way valve 013 is used to allow the oil to flow in one direction.

[0064] Among them, such as Figure 16 As shown, the hydraulic pump 011 system 01 includes a hydraulic pump 011, which is threadedly connected to an electric motor 014. The hydraulic pump 011 is threadedly connected to a mounting seat 0011, and a fluid flow channel is provided on the mounting seat 0011. The filter device 012 and the one-way valve 013 are both installed in the fluid flow channel. The mounting seat 0011 is fixedly and sealedly connected to the integrated control valve body 0012. The other end of the integrated control valve body 0012 is provided with a hydraulic pump mounting hole 001205, and the fluid flow channel is connected to the hydraulic pump mounting hole 001205.

The mounting seat 0011 is sealed and connected to the sealing hole section, and the mounting seat 0011 is threadedly connected to the hydraulic pump 011.

[0066] Among them, such as Figure 12 As shown, the integrated control valve body 0012 is provided with a first pressure channel 00121, a second pressure channel 00122, a third pressure channel 00123, a fourth pressure channel 00124 and a fifth pressure channel 00125.

[0067] The first pressure through channel 00126 of this embodiment is used to connect the first pressure channel 00121, the second pressure channel 00122 and the third pressure channel 00123. Since the first pressure channel 00121 is connected to the fourth pressure channel 00124, and the third pressure channel 00123 is connected to the fifth pressure channel 00125, the first pressure channel 00121, the second pressure channel 00122, the third pressure channel 00123, the fourth pressure channel 00124 and the fifth pressure channel 00125 of this embodiment are connected to each other.

[0068] Among them, one end of the integrated control valve body 0012 is also provided with a first pressure output hole 00127 and a second pressure output hole 00128, and the first pressure output hole 00127 and the second pressure output hole 00128 are fixedly and sealedly connected with a pressure output shaft 0015, and the two pressure output shafts 0015 are both sealed and connected to the downhole tool. The first pressure output hole 00127 is connected to the first piston chamber 03 of the downhole tool through the flow channel of the corresponding pressure output shaft 0015, and the second pressure output hole 00128 is connected to the second piston chamber 04 of the downhole tool through the flow channel of the corresponding pressure output shaft 0015; one end of the integrated control valve body 0012 is fixedly connected to the fixing plate 0013 by a fastening screw 0014, and the two pressure output shafts 0015 both pass through the fixing plate 0013.

[0069] For the first pressure output hole 00127 and the second pressure output hole 00128, both include a sealing hole section, a threaded hole section and a blind hole section; a pressure output shaft 0015 is fixedly connected to the first pressure output hole 00127 and the second pressure output hole 00128 through threads, and the sealing part of the pressure output shaft 0015 cooperates with the corresponding sealing hole section to form a seal.

[0070] like Figure 13 As shown, the first pressure output hole 00127 is connected to the first external port of the first two-position three-position normally closed solenoid valve 021 through a second pressure through-channel 001201, and the second pressure output hole 00128 is connected to the first external port of the second two-position three-position normally closed solenoid valve 022 through a second pressure through-channel 001201.

[0071] For the second pressure through-channel 001201, one is used to connect the first pressure output hole 00127 and the first external port of the first two-position three-way normally closed solenoid valve 021, and the other is used to connect the second pressure output hole 00128 and the first external port of the second two-position three-way normally closed solenoid valve 022, and a plug is provided at the second pressure through-channel 001201 as needed to achieve pressure sealing.

[0073] The setting of the third pressure through-channel 00120 realizes the connection between the third external port (R port) of the first two-position three-dimensional normally closed solenoid valve 021 and the third external port (R port) of the second two-position three-dimensional normally closed solenoid valve 022 and the return oil channel 00129, so that the hydraulic oil flowing out from the third external port (R port) of the first two-position three-dimensional normally closed solenoid valve 021 or the third external port (R port) of the second two-position three-dimensional normally closed solenoid valve 022 can smoothly flow back to the oil storage chamber 07 through the third pressure through-channel 00120 and the return oil channel 00129.

[0074] In the aforementioned embodiment, the actuator unit 02 of the integrated control module 00 includes a first, two-position, three-position normally closed solenoid valve 021 and a second, two-position, three-position normally closed solenoid valve 022. The entire integrated control module 00 comprises an electric motor 014, a micro-hydraulic pump 011, a filter device 012, a high-pressure check valve, a high-pressure relief valve 06, the first, two-position, three-position normally closed solenoid valve 021, the second, two-position, three-position normally closed solenoid valve 022, and a differential pressure sensor. The integrated control module 00 is entirely immersed in an oil reservoir 07, which provides pressure balancing. The electric motor 014 and micro-hydraulic pump 011 provide high-pressure fluid to the entire control module. The high-pressure relief valve 06 safeguards the entire hydraulic system. When pressure exceeds a set value, the relief valve 06 opens, allowing fluid to flow back into the oil reservoir 07. The solenoid valves enable directional control of the hydraulic channel. By controlling the activation or deactivation of the solenoid valves, the cylinder's bidirectional axial movement is controlled. The pressure sensor is a differential pressure sensor, monitoring the pressure difference between the oil reservoir 07 and the high-pressure hydraulic line. When the hydraulic cylinder moves to the limit position, the pressure will rise sharply. When the pressure difference reaches the set value, the control unit first closes the solenoid valve and the electric motor 014 at the same time to prevent the hydraulic components from being damaged by high pressure.

[0075] As an alternative to the two solenoid valves, the execution unit 02 in this embodiment includes a first, second, two-position, two-way normally closed solenoid valve 08, a second, second, two-position, two-way normally closed solenoid valve 09 and a reverse shuttle valve 010; wherein, the first external port of the first, second, two-position, two-way normally closed solenoid valve 08 is communicated with the first piston chamber 03 of the downhole tool, the first external port of the second, second, two-position, two-way normally closed solenoid valve 09 is communicated with the second piston chamber 04 of the downhole tool, the second external port of the first, second, two-position, two-way normally closed solenoid valve 08 and the second external port of the second, second, two-position, two-way normally closed solenoid valve 09 are both communicated with the oil outlet of the hydraulic pump 011, the first external port of the first, second, two-position, two-way normally closed solenoid valve 08 is communicated with the first inlet (M port) of the reverse shuttle valve 010, and the second external port of the second, second, two-position, two-way normally closed solenoid valve 09 is communicated with the first inlet (M port) of the reverse shuttle valve 010. The first external port of the normally closed solenoid valve 09 is connected to the second inlet (N port) of the reverse shuttle valve 010, and the outlet (O port) of the reverse shuttle valve 010, the second external port of the first and second two-position two-way normally closed solenoid valve 08 and the second external port of the second two-position two-way normally closed solenoid valve 09 are all connected to the oil storage chamber 07; when the execution unit 02 is in the first state, the first and second two-position two-way normally closed solenoid valve 08 is powered on, and the second two-position two-way normally closed solenoid valve 09 is powered on; when the execution unit 02 is in the second state, the first and second two-position two-way normally closed solenoid valve 08 is powered off, and the second two-position two-way normally closed solenoid valve 09 is powered on; when the execution unit 02 is in the third state, the first and second two-position two-way normally closed solenoid valve 08 and the second two-position two-way normally closed solenoid valve 09 are both powered off.

[0076] In the case where the execution unit 02 includes a first two-position two-way normally closed solenoid valve 08, a second two-position two-way normally closed solenoid valve 09 and a reverse shuttle valve 010, when the execution unit 02 is in the first state, such as Figure 10 As shown, at this time, the first two-position two-way normally closed solenoid valve 08 is energized, the first external port (P port) of the first two-position two-way normally closed solenoid valve 08 is connected to the second external port (C port) of the first two-position two-way normally closed solenoid valve 08, the second two-position two-way normally closed solenoid valve 09 is de-energized, the first external port of the second two-position two-way normally closed solenoid valve 09 and the second external port of the second two-position two-way normally closed solenoid valve 09 are cut off, and after the hydraulic pump 011 is started, the hydraulic oil flows into the first piston chamber 03 of the downhole tool through the first two-position two-way normally closed solenoid valve 08, pushing the piston of the downhole tool to move right, and the hydraulic oil in the second piston chamber 04 of the downhole tool flows back to the oil storage chamber 07 through the second inlet (N port) and the outlet (O port) of the reverse shuttle valve 010.

[0077] When the execution unit 02 is in the second state, Figure 9As shown, at this time, the first two-position two-way normally closed solenoid valve 08 is powered off, and the first external port (P port) of the first two-position two-way normally closed solenoid valve 08 is not connected to the second external port (C port) of the first two-position two-way normally closed solenoid valve 08, and the second two-position two-way normally closed solenoid valve 09 is powered on, and the first external port of the second two-position two-way normally closed solenoid valve 09 is connected to the second external port of the second two-position two-way normally closed solenoid valve 09. After the hydraulic pump 011 is started, the hydraulic oil flows into the second piston chamber 04 of the downhole tool through the second two-position two-way normally closed solenoid valve 09, pushing the piston of the downhole tool to move left, and the hydraulic oil in the first piston chamber 03 of the downhole tool flows back to the oil storage chamber 07 through the first inlet (M port) and the outlet (O port) of the reverse shuttle valve 010.

[0078] When the execution unit 02 is in the third state, Figure 8 As shown, at this time, the first two-position two-way normally closed solenoid valve 08 and the second two-position two-way normally closed solenoid valve 09 are both de-energized, the hydraulic oil does not flow, and the state of the downhole tool remains unchanged.

[0079] In this embodiment, the integrated control module 00 comprises an electric motor 014, a hydraulic pump 011, a filter device 012, a one-way valve 013, a relief valve 06, a first two-position, two-way normally closed solenoid valve 08, a second two-position, two-way normally closed solenoid valve 09, a reverse shuttle valve 010, and a differential pressure sensor 05. In this embodiment, the solenoid valves employ two two-position, two-way normally closed solenoid valves to achieve directional control of the hydraulic channel. By controlling the activation or deactivation of the solenoid valves, the cylinder's bidirectional axial movement is controlled. Leveraging the switching characteristics of the reverse shuttle valve 010, a reverse shuttle valve 010 is provided to return the fluid from the hydraulic chamber.

[0080] The embodiment of the present invention further provides a production sliding sleeve, which is mainly composed of a control cable 1, a cable sealing assembly 2, an upper joint 3, an upper outer tube 4, an upper center tube 5, an intermediate connector 6, a lower outer tube 7, a lower center tube 8, an integrated control module 00, a pressure transmission sleeve 11, a sliding sleeve 12, a connecting sleeve 10, and a lower joint 13.

[0081] like Figure 4 、 Figure 5 and Figure 6As shown, the upper joint 3, the upper outer tube 4, the upper central tube 5 and the intermediate connector 6 constitute a first chamber. The control unit connected to the integrated control module 00 is arranged in the first chamber. The control unit specifically includes a solenoid valve control circuit board, a pressure sensor acquisition circuit board, a motor drive board, a main control circuit board, a power module and a communication module (not shown in the figure). The control unit is connected to the ground control device by a control cable 1. The control cable 1 is installed on the upper joint 3 through a cable sealing assembly 2. To ensure the sealing of the first chamber and the normal operation of the internal control unit, sealing rings are correspondingly provided between the upper joint 3, the upper outer tube 4, the upper central tube 5 and the intermediate connector 6.

[0082] The intermediate connector 6, lower outer tube 7, lower center tube 8, and pressure transmission sleeve 11 form the second chamber, which is a self-contained pressure-balanced oil storage chamber 07. The interior of the oil storage chamber 07 is filled with high-cleanliness hydraulic oil. The integrated control module 00 is entirely immersed in the hydraulic oil, and the integrated control module 00 is fixed to the upper end face of the pressure transmission sleeve 11 by fastening screws 0014 or other fastening methods. It can also be fixed to the lower center tube 8 by fastening screws 0014 or other fastening methods. To ensure the sealing of the second chamber, to ensure the cleanliness of the internal hydraulic oil, and to ensure the normal operation of the integrated control module 00, sealing rings are provided as needed between the intermediate connector 6, lower outer tube 7, lower center tube 8, and pressure transmission sleeve 11.

[0083] like Figure 7 As shown, three sealing structures 9 are provided between the sliding sleeve 12 and the pressure transmission sleeve 11. A first piston chamber is formed between the two upper sealing structures 9, and a second piston chamber for producing the sliding sleeve is formed between the two lower sealing structures 9. The cross-sectional areas of the first piston chamber and the second piston chamber are the same. When there is no pressure output from the integrated control module 00, the first piston chamber and the second piston chamber can achieve pressure balance, and the sliding sleeve 12 will not move axially to trigger the sliding sleeve switch action.

[0084] When the execution unit 02 of the integrated control module 00 is in the first state, the hydraulic pump 011 system 01 can pump the hydraulic oil in the oil storage chamber 07 to the first piston chamber of production through the execution unit 02, and the hydraulic oil in the second piston chamber of production can flow back to the oil storage chamber 07 through the execution unit 02, so that the sliding sleeve 12 moves axially to the left under the action of pressure, thereby realizing the closing of the production sleeve; conversely, when the execution unit 02 of the integrated control module 00 is in the second state, the sliding sleeve 12 moves axially to the right under the action of pressure, thereby realizing the opening of the production sleeve; when the execution unit 02 of the integrated control module 00 is in the third state, there is no flow of hydraulic oil, and the production sleeve maintains the current state.

[0085] For the production sleeve of the embodiment of the present invention, when the execution unit 02 includes a first, second, third, and fourth normally closed solenoid valve 021 and a second, second, third, and fourth normally closed solenoid valve 022: when the production sleeve needs to be opened, the piston needs to be moved to the left. At this time, the control method of the integrated control module 00 is as follows: the second, second, third, and fourth normally closed solenoid valve 022 is powered on and turned on, controlling the first, second, third, and fourth normally closed solenoid valve 021 to be in a closed state, starting the electric motor 014, and the hydraulic oil enters the sleeve opening chamber through the second, second, third, and fourth normally closed solenoid valve 022, pushing the piston to move toward the closing chamber, and the sleeve opens; the low-pressure fluid in the closing chamber returns to the oil storage chamber 07 through the first, second, third, and fourth normally closed solenoid valve 021; when it reaches the fully open position, the pressure rises sharply, and the value of the pressure differential sensor 05 increases. When the pressure differential sensor 05 reaches the preset pressure, the second, second, third, and fourth normally closed solenoid valve 022 is turned off, and the pressure pump is turned off at the same time, and the high-pressure oil returns to the oil storage chamber 07 through the overflow valve 06.

[0086] When the production sleeve needs to be closed, the piston needs to move to the right. At this time, the control method of the integrated control module 00 is as follows: control the first two-position three-way normally closed solenoid valve 021 to be powered on and open, control the second two-position three-way normally closed solenoid valve 022 to be in the closed state, start the electric motor 014, and the hydraulic oil enters the sleeve closing chamber through the first two-position three-way normally closed solenoid valve 021, pushing the piston to move toward the opening chamber, and the sleeve is closed; the low-pressure fluid in the opening chamber returns to the oil storage chamber 07 through the second two-position three-way normally closed solenoid valve 022; when it reaches the fully closed position, the pressure rises sharply, and the value of the pressure differential sensor 05 increases. When the pressure differential sensor 05 reaches the preset pressure, the first two-position three-way normally closed solenoid valve 021 is turned off, and the pressure pump is turned off at the same time, and the high-pressure oil returns to the oil storage chamber 07 through the overflow valve 06.

[0087] For the production sleeve of the embodiment of the present invention, when the execution unit 02 includes a first, second, two-position normally closed solenoid valve 08, a second, second, two-position normally closed solenoid valve 09 and a reverse shuttle valve 010: when the production sleeve needs to be opened, the piston needs to move to the left. At this time, the control method of the integrated control module 00 is as follows: the second, second, two-position normally closed solenoid valve 09 is powered on and opened, the first, second, two-position normally closed solenoid valve 08 is in a closed state, the electric motor 014 is started, and the hydraulic oil enters the sleeve opening chamber through the second, second, two-position normally closed solenoid valve 09, pushing the piston to move toward the closing chamber, and the sleeve opens; the low-pressure fluid in the closing chamber returns to the oil storage chamber 07 through the reverse shuttle valve 010; when it reaches the fully open position, the pressure rises sharply, and the value of the pressure differential sensor 05 increases. When the pressure differential sensor 05 reaches the preset pressure, the second, second, two-position normally closed solenoid valve 09 is turned off, and the pressure pump is turned off at the same time, and the high-pressure oil returns to the oil storage chamber 07 through the overflow valve 06.

[0088] When the production sleeve needs to be opened, the piston moves to the right. The integrated control module 00 controls the process as follows: The first, second, and third normally closed solenoid valve 08 is powered on and opened, while the second, second, second, second normally closed solenoid valve 09 is closed. Electric motor 014 is activated, and hydraulic oil enters the sleeve's closing chamber through the first, second, second, second normally closed solenoid valve 08, pushing the piston toward the opening chamber, closing the sleeve. The low-pressure fluid in the opening chamber returns to the oil reservoir 07 via the reverse shuttle valve 010. When the fully open position is reached, the pressure rises sharply, and the value on the differential pressure sensor 05 increases. When the differential pressure sensor 05 reaches the preset pressure, the first, second, second, second normally closed solenoid valve 08 is closed, simultaneously shutting off the pressure pump. High-pressure oil returns to the oil reservoir 07 through the relief valve 06.

[0089] During specific use, ground operators operate the ground control device and send control instructions to the tool installed with the integrated control module 00 underground through a control cable 1. The instructions control the integrated control module 00 through the control unit inside the downhole tool, control the start and stop of the motor, realize the output of bidirectional pressure, and thus control various actions of the downhole tool.
