[0001] This invention relates to the field of wellbore data acquisition equipment technology, and is an intelligent wellbore data acquisition device. Background Technology

[0002] Oil well data acquisition is a crucial task. To ensure the accuracy and integrity of the data, we employ intelligent data acquisition equipment. This equipment extends deep into the well via a guide wire and relies on its built-in data acquisition module for precise data acquisition. The data acquisition module is highly professional and multifunctional, effectively acquiring oil wellbore data, thereby providing strong data support for the oil extraction process.

[0003] However, the above-mentioned technologies often have the following drawbacks: Given the complexity of the downhole environment, when the data acquisition equipment is being lowered, the wires need to be stretched to a long length, which may cause the data acquisition equipment to shake. This shaking increases the risk of the data acquisition equipment colliding with the well wall, which may damage the key components inside the equipment and thus adversely affect the accuracy of data acquisition. Therefore, the present invention provides an intelligent wellbore data acquisition device. Summary of the Invention

[0004] This invention provides an intelligent wellbore data acquisition device that overcomes the shortcomings of the prior art. It can effectively solve the problem that the existing data acquisition devices require a long extension of the lead wire during the lowering process, which causes the data acquisition device to shake and increases the risk of collision between the data acquisition device and the well wall.

[0005] The technical solution of the present invention is achieved through the following measures: an intelligent wellbore data acquisition device includes a shell and a baffle plate. A data acquisition module is installed inside the shell. A wire is installed at the top of the shell and is electrically connected to the data acquisition module. Two sets of identical telescopic structures are evenly distributed along the circumference of the outer side of the shell. The outer ends of the telescopic structures can press against the well wall to keep the shell centered inside the well. The lower part of the shell has an opening that runs through the inside and outside. The upper part of the shell has a sliding groove. The upper part of the baffle plate is located in the sliding groove, and the lower part of the baffle plate can block the opening. A driving mechanism that can drive the baffle plate to move up and down is installed inside the telescopic structure.

[0006] The following are further optimizations and / or improvements to the above-mentioned technical solution: Preferably, the telescopic structure includes a connecting rod, an adjusting rod, and an arc-shaped block. The connecting rod is installed on the outer side of the outer shell and is a hollow structure. The inner end of the adjusting rod is located inside the connecting rod. A sliding plate is installed on the inner end of the adjusting rod. A first spring is installed between the sliding plate and the inner side of the outer end of the connecting rod.

[0007] Preferably, the telescopic structure also includes an electromagnet, and an electromagnet that is magnetically attracted to the slider is fixedly connected inside the connecting rod, with the electromagnet positioned close to the outer shell.

[0008] Preferably, the telescopic structure further includes a first connecting pipe and a second connecting pipe. The first connecting pipe and the second connecting pipe are installed on the connecting rod at intervals. The second connecting pipe is close to the outer shell. The driving mechanism includes a control valve disposed in the second connecting pipe. The connecting rod is connected to the slide groove. The inner end of the connecting rod is fixedly connected to the connecting valve. The upper end of the baffle is fixedly connected to the upper end of the slide groove. A second spring is fixedly connected between the upper end of the baffle and the upper end of the slide groove.

[0009] Preferably, the upper end of the baffle is provided with an upward-opening groove near the inner position, and the inner side of the baffle is provided with multiple sets of air outlets communicating with the groove. An elastic sheet is fixedly connected inside the air outlet, and a shrinkage hole is opened on the elastic sheet. The shrinkage hole can be opened under the push of gas and communicate with the data acquisition module.

[0010] Preferably, the baffle has a cavity near the outside, and the outer wall of the baffle has a set of air outlet grooves communicating with the cavity. A push block is slidably and sealed inside the cavity. A third spring is fixedly connected between the top surface of the push block and the inner side of the upper end of the cavity. The top surface of the baffle has a round hole communicating with the cavity, and a push rod corresponding to the round hole is fixedly connected to the inner side of the upper end of the groove.

[0011] Preferably, the adjusting rod has a water storage tank near its outer side, and a water injection pipe connected to the water storage tank is installed on the adjusting rod.

[0021] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0022] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as front, back, top, bottom, left, right, etc. The positional relationships are determined based on the layout direction of the attached diagram in the instruction manual.

[0023] The present invention will be further described below with reference to embodiments and accompanying drawings: Example 1: As shown in the attached document Figure 1-6 As shown, the intelligent wellbore data acquisition device includes a housing 1 and a baffle 13. A data acquisition module 2 is installed inside the housing 1. A wire is installed at the top of the housing 1 and is electrically connected to the data acquisition module 2. Two sets of identical telescopic structures are evenly distributed around the outer side of the housing 1. The outer ends of the telescopic structures can press against the well wall to keep the housing 1 centered inside the well. The lower part of the housing 1 has an opening 11 that runs through the inside and outside. The upper part of the housing 1 has a sliding groove 12. The upper part of the baffle 13 is located in the sliding groove 12, and the lower part of the baffle 13 can block the opening 11. The telescopic structure has a drive mechanism that can drive the baffle 13 to move up and down.

[0024] During use, the telescopic structure is retracted inward to smoothly lower the outer casing 1 into the well. Releasing the telescopic structure allows it to automatically extend outward and reset, fitting tightly against the well wall, ensuring the outer casing 1 is centered within the well. This prevents the wire from colliding with the well wall during the lowering process, effectively protecting the data acquisition module 2. Subsequently, the outer casing 1 is lowered to the predetermined position within the well using the wire. The data acquisition module 2 then collects well data, which is transmitted to a receiver on the ground via the wire to complete the entire data acquisition process. When the data acquisition module 2 is in operation, the outer casing 1 may obstruct its perception of external data, thus affecting its working efficiency. To address this issue, a drive mechanism is employed. This mechanism effectively drives the baffle 13 upward, creating an unobstructed working environment for the data acquisition module 2. After the data acquisition module 2 completes its data acquisition task, the drive mechanism is reactivated, driving the baffle 13 downward to close the opening 11, ensuring the data acquisition module 2 is adequately protected.

[0025] The above-mentioned intelligent wellbore data acquisition equipment can be further optimized and / or improved according to actual needs: Example 2: As shown in the attached document Figure 1-2 As shown, the telescopic structure includes a connecting rod 3, an adjusting rod 4, and an arc-shaped block 5. The connecting rod 3 is installed on the outside of the outer shell 1. The connecting rod 3 is a hollow structure. The inner end of the adjusting rod 4 is located inside the connecting rod 3. A sliding plate 7 is installed on the inner end of the adjusting rod 4. A first spring is installed between the sliding plate 7 and the inner side of the outer end of the connecting rod 3. The arc-shaped block 5 is fixedly connected to the outer end of the adjusting rod 4. An installation groove is provided at the center of the outer side of the arc-shaped block 5. A round shaft 6 is rotatably connected in the installation groove. Before lowering the shell into the well, the adjusting rod 4 is moved to retract into the connecting rod 3, so that the outer shell 1 is smoothly placed into the well. Then, the adjusting rod 4 is released. At this time, the first spring will play a role, pulling the sliding plate 7, which in turn pushes the adjusting rod 4. The movement of the adjusting rod 4 will drive the arc-shaped block 5, so that the round shaft 6 fits tightly against the well wall, ensuring that the outer shell 1 is placed in the center of the well.

[0026] Example 3: As shown in the attached document Figure 1-2 As shown, the telescopic structure also includes an electromagnet 10. An electromagnet 10, magnetically attracted to the slider 7, is fixedly connected inside the connecting rod 3. The electromagnet 10 is positioned close to the outer casing 1. The circular shaft 6 maintains contact with the well wall due to the thrust of the first spring. If there are agglomerated impurities obstructing the arc-shaped block 5 within the well wall, it will adversely affect the lowering process of the outer casing 1. By activating the electromagnet 10, it attracts the slider 7 to move, thereby causing the adjusting rod 4 to shift. This action will cause the arc-shaped block 5 to move away from the well wall, thus avoiding the agglomerated impurities. After the arc-shaped block 5 is lowered to below the position of the agglomerated impurities, the electromagnet 10 is deactivated. At this time, the first spring will function, pulling the slider 7 back to its original position, thereby causing the adjusting rod 4 to return to its original position.

[0027] Example 4: As shown in the appendix Figure 2 As shown, the telescopic structure also includes a first connecting pipe 8 and a second connecting pipe 9. The first connecting pipe 8 and the second connecting pipe 9 are installed on the connecting rod 3 at intervals. The second connecting pipe 9 is close to the outer shell 1. The driving mechanism includes a control valve disposed in the second connecting pipe 9. The connecting rod 3 is connected to the slide groove 12. The inner end of the connecting rod 3 is fixedly connected to the connecting valve 14. The upper end of the baffle 13 is fixedly connected to the upper end of the slide groove 12. A second spring is fixedly connected between the upper end of the baffle 13 and the upper end of the slide groove 12. When the adjusting rod 4 needs to be moved, the control valve is in the open state and the connecting valve 14 is in the closed state. At this time, the gas in the connecting rod 3 pushed by the sliding plate 7 during its movement will be discharged from the second connecting pipe 9. When the baffle 13 needs to seal the opening 11, simply close the control valve and then open the connecting valve 14. Then move the sliding plate 7 to the side closer to the outer casing 1. At this time, the gas in the connecting rod 3 will only enter the slide groove 12 and push the baffle 13 downward, so that the baffle 13 seals the opening 11. Then close the connecting valve 14. At this time, the gas in the slide groove 12 will be in a closed state, so that the baffle 13 cannot be pulled by the second spring. When the adjusting rod 4 needs to be reset, simply open the control valve. At this time, the outside gas will enter the connecting rod 3 from the second connecting pipe 9, so that the adjusting rod 4 will be reset under the drive of the first spring. When the baffle 13 needs to be moved upward, simply open the connecting valve 14 to allow the gas in the slide groove 12 to enter the adjusting rod 4 and then be discharged from the second connecting pipe 9. At this time, the second spring will pull the baffle 13 to move upward.

[0028] Example 5: As shown in the attached document Figure 3 As shown, the upper end of the baffle 13 is provided with an upward-opening groove 15 near the inner position. The inner side of the baffle 13 is provided with multiple sets of air outlets communicating with the groove 15. An elastic sheet 16 is fixedly connected inside the air outlet. A shrinkage hole is opened on the elastic sheet 16. The shrinkage hole can be opened under the push of gas and communicate with the data acquisition module 2. The complexity of the downhole environment and the high humidity level can adversely affect the normal operation of the data acquisition module 2. During the process of the baffle 13 being pushed by the gas in the connecting rod 3 to seal the opening 11, the air pressure in the slide groove 12 is insufficient to open the constriction orifice on the elastic plate 16. After the connecting valve 14 is closed and the first control valve is opened, air is introduced, and the adjusting rod 4 will reset. At this time, the first control valve can be closed, and then the connecting valve 14 can be opened. Then, the slide 7 can be moved to one side of the outer shell 1. At this time, the slide 7 will push the gas in the connecting rod 3 into the slide groove 12. On the basis of the baffle 13 being sealed, air continues to be introduced. The gas will act on the constriction orifice on the elastic plate 16, causing it to open. Then the airflow is guided to the data acquisition module 2 for air drying, ensuring that the data acquisition module 2 maintains its normal operating state and is not affected by external factors such as humidity.

[0029] Example 6: As shown in the appendix Figure 4 As shown, a cavity 17 is provided near the outer side of the baffle 13. A set of air outlet grooves 18 communicating with the cavity 17 are provided on the outer wall of the baffle 13. A push block 21 is slidably and sealingly connected inside the cavity 17. A third spring is fixedly connected between the top surface of the push block 21 and the inner side of the upper end of the cavity 17. A circular hole 20 communicating with the cavity 17 is provided on the top surface of the baffle 13. A push rod 19 corresponding to the circular hole 20 is fixedly connected to the inner side of the upper end of the sliding groove 12. During the upward movement of the baffle 13, the push rod 19 enters the cavity 17 through the circular hole 20. The push rod 19 pushes the push block 21 downward, thereby effectively blowing out the gas inside the cavity 17 through the air outlet grooves 18, thus removing impurities around the outer casing 1. This ensures that the data acquisition module 2 performs data acquisition in a relatively clean environment, thereby improving the accuracy and reliability of data acquisition. When the baffle 13 moves downward, the push block 21 is reset under the pull of the third spring.

[0030] Example 7: As attached Figure 5 As shown, the adjusting rod 4 has a water storage tank 22 near its outer side. A water injection pipe 24 is installed on the adjusting rod 4 and communicates with the water storage tank 22. A one-way valve is connected to the water inlet in the water injection pipe 24. A push plate 23 is slidably connected inside the water storage tank 22. A first elastic rope is connected between the push plate 23 and the inner side of the water storage tank 22. A connecting groove 25 communicating with the water storage tank 22 is provided near the inner side of the adjusting rod 4. A fixed rod 26 that can slide in the connecting groove 25 and push the push plate 23 is installed on the outer side of the connecting valve 14. A through groove 27 communicating with the water storage tank 22 is provided on the inner side of the arc-shaped block 5. A water outlet groove 28 communicating with the through groove 27 is provided on the outer wall of the arc-shaped block 5. Because there will be impurities on the well wall, as the round shaft 6 rolls on the well wall, these impurities will stick to the round shaft 6, which will increase the friction between the round shaft 6 and the well wall, thus affecting the lowering speed of the outer shell 1. The present invention injects water into the water storage tank 22 through the water injection pipe 24, so that the water is stored in the water storage tank 22. Then, when it is necessary to clean the round shaft 6, the adjusting rod 4 moves to the side closer to the outer shell 1. At this time, the fixing rod 26 will enter the water storage tank 22 from the connecting groove 25 and push the push plate 23. At this time, the push plate 23 will push the water in the water storage tank 22 into the through groove 27, and finally spray it from the water outlet 28 onto the round shaft 6 to clean the round shaft 6, thereby reducing the friction between the round shaft 6 and the well wall. The water outlet 28 is tilted and the water outlet end of the water outlet 28 faces downward. The water outlet 28 is offset from the central axis of the circular shaft 6. By setting the position of the water outlet 28, the water can push the circular shaft 6 to rotate when it is sprayed out of the water outlet 28, so that the circular shaft 6 can be thoroughly cleaned when it rotates.

[0031] Example 8: As attached Figure 6As shown, a connecting block 29 is slidably connected to the inner wall of the water outlet 28. Multiple sets of micro-holes are formed on the connecting block 29. A second elastic rope connects the inner side of the connecting block 29 to the inner wall of the through groove 27. A set of bristles 30 is fixedly connected to the outer side of the connecting block 29. When water enters the water outlet 28, the connecting block 29 is pushed by the water, causing the bristles 30 to contact the round shaft 6. Then, the water is sprayed out from the micro-holes. At this time, the water is pressurized by the micro-holes to increase the impact force on the round shaft 6, allowing the round shaft 6 to rotate better. While the round shaft 6 is rotating, the bristles 30 can also clean the round shaft 6, improving the cleaning effect.

[0032] In a field test conducted in the ZhaoX block of a development zone, this invention effectively prevented the conductor from colliding with the well wall during the lowering of the outer casing, avoided the formation of impurities on the well wall, protected the data acquisition module, ensured the normal operation of the data acquisition module, and improved the accuracy, safety, and reliability of data acquisition.

[0033] The above technical features constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
