Description

Technical Field

[0001] The utility model relates to the technical field of downhole tools, in particular to a high-temperature and high-pressure downhole tool test clamping device. Background Technique

[0002] In downhole operations such as oil drilling and geological drilling, downhole tools are widely used. Due to the usually complex downhole operation environment, downhole tools have to withstand the erosion of high-pressure drilling fluid and at the same time ensure the transmission of drilling pressure and torque to the drill bit, which requires high performance of downhole tools.

[0003] Existing downhole tools usually use special test devices or simulate test wells at the well site to conduct performance tests on downhole tools. However, in actual use, researchers found that in order to support downhole tools of different lengths and sizes, this device realizes it by sliding the support frame in the through groove. However, the through groove faces the downhole tool being tested. When performing pressure tests on downhole tools, it will break and splash, resulting in debris falling into the through groove, which is not conducive to cleaning. Moreover, it is inconvenient to limit and support downhole tools of different diameters, which is not conducive to popularization and use. There is a need for a high-temperature and high-pressure downhole tool test clamping device to solve the above technical problems. Summary of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a high-temperature and high-pressure downhole tool test clamping device, which has the advantages of clamping the two ends of the downhole tool by the clamping seat and the second clamping seat respectively, and clamping and limiting the side positioning plates by positioning bolts, ensuring that the downhole tool is clamped and fixed between the clamping seat and the second clamping seat without loosening. At the same time, the debris generated by the test fragmentation directly splashes into the stable frame and is received by the receiving tray. After all the downhole tool pressure tests are completed, the receiving tray is directly pulled out from the front of the stable seat for cleaning. This effectively reduces the cleaning difficulty and can keep the downhole tool fixed during the compressive test, avoiding loosening and affecting the accuracy of the pressure test. The above technical problems are solved.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solution: A high-temperature and high-pressure downhole tool test clamping device, including a processing table, a stabilizing base is arranged on the top surface of the processing table, a cross plate is arranged between the stabilizing bases, a hydraulic rod is arranged on the bottom surface of the cross plate, a compaction plate is arranged on the bottom surface of the hydraulic rod, reinforcing bases are arranged at both ends of the stabilizing base, a reinforcing plate is arranged on the top surface of the reinforcing base, a bearing seat is arranged on the top surface of the processing table, a stabilizing frame is arranged on the top surface of the bearing seat, support seats are arranged at both ends of the stabilizing frame, a clamping seat is arranged on the top surface of the support seat, a positioning plate is arranged on the front surface of the clamping seat, a material receiving tray is arranged inside the stabilizing frame, a support plate is arranged on the top surface of the processing table, and a reinforcing plate is arranged on the bottom surface of the reinforcing base.

[0008] Preferably, both ends of the top surface of the processing table are fixedly connected to the stabilizing bases respectively, and the cross plate is fixedly welded between the stabilizing bases. Hydraulic pumps are fixedly connected to both ends of the inner wall of the cross plate respectively, and the output end of the hydraulic pump is fixedly connected to the hydraulic rod. The compaction plate is installed in a lifting manner on the bottom surface of the cross plate.

[0009] Through the above technical solution, the downhole tool is placed corresponding to the limiting grooves inside the clamping seat. After it is completely placed, the clamping seat is rotated to be installed and fitted with the second clamping seat. After the positioning plates on the front surfaces of the clamping seat and the second clamping seat are closely fitted, they are reinforced with positioning bolts. This ensures that during the process of the clamping seat driving the second clamping seat to clamp and position the downhole tool, loosening between the clamping seat and the second clamping seat is avoided, which may affect the normal clamping work of the downhole tool. During the process of using the hydraulic rod to drive the compaction plate for pressure testing, the clamping seat and the second clamping seat can clamp and position the downhole tool, thereby effectively improving the fastening effect of the downhole tool and also improving the pressure measurement accuracy of the downhole tool. After the downhole tool is clamped and fixed, the hydraulic pump is started. The output end of the hydraulic pump drives the hydraulic rod to move linearly to perform pressure testing on the downhole tool at the bottom end. During the testing process, the pressure sensor between the compaction plates can record the pressure value borne by the downhole tool and transmit its test data signal to the control panel, which is convenient for the operator to directly record the data after the test, improving the pressure measurement accuracy of the downhole tool and also improving the use effect of the device. At the same time, the operation method is simple and convenient.

[0010] Preferably, the bottom surface of the hydraulic rod is fixedly connected to a balance plate, and a weight steel plate is fixedly connected to the bottom surface of the balance plate. The weight steel plate is fixedly connected to the compaction plate at the bottom, and a pressure sensor is fixedly connected between the compaction plates. The bottom surface of the compaction plate corresponds to the stabilizing frame.

[0011] Through the above technical solution, the support plate and the bearing seat can stably support the top stabilizing frame. The support seats at both ends of the stabilizing frame drive the clamping seat to be fixedly connected to the stabilizing seat, and there is a gap between the clamping seat and the stabilizing seat, ensuring that the clamping seat can normally open and close to clamp and fix the downhole tool. When the clamping seat drives the support seat to be fixedly connected to the processing table and the stabilizing seat respectively, pressure measurement work is carried out, avoiding the deviation of the support seat during the pressure test of the downhole tool, which affects the accuracy of the test data of the downhole tool. At the same time, the debris generated by the test fragmentation directly splashes into the stabilizing frame and is received by the material receiving tray. After completing the pressure measurement of all downhole tools, the material receiving tray is directly pulled out from the front of the stabilizing seat for cleaning, thereby effectively reducing the difficulty of debris cleaning while ensuring that the support seat conducts pressure tests on the downhole tool under fixed conditions, solving the problem of inconvenience in limiting and supporting downhole tools with different diameters, and facilitating its popularization and use.

[0012] Preferably, a bearing seat is fixedly connected between the stabilizing frame and the support plate. Support seats are respectively fixedly connected to both ends of the stabilizing frame, and the sides of the support seats are fixedly welded to the stabilizing seat respectively. The support plate is fixedly installed on the bottom surfaces of the stabilizing frame and the support seat.

[0013] Through the above technical solution, the clamping seat and the second clamping seat respectively clamp both ends of the downhole tool, and the side positioning plates are clamped and limited by positioning bolts, ensuring that the clamping seat and the second clamping seat do not loosen during the process of clamping and fixing the downhole tool. At the same time, the debris generated by the test fragmentation directly splashes into the stabilizing frame and is received by the material receiving tray. After completing the pressure measurement of all downhole tools, the material receiving tray is directly pulled out from the front of the stabilizing seat for cleaning, thereby effectively reducing the cleaning difficulty while keeping the downhole tool fixed during the compressive test, avoiding loosening and affecting the accuracy of the pressure test.

[0014] Preferably, the second clamping seat is installed in an opening and closing manner on the bottom surface of the clamping seat, and the clamping seat and the second clamping seat are connected by a hinge. An installation groove is formed between the clamping seat and the second clamping seat, and anti-slip sticker blocks are fixedly connected to the inner wall of the installation groove. The installation grooves are symmetrically arranged.

[0015] Through the above technical solution, both ends of the stabilizing seat are fixedly connected to the processing table by the reinforcement seat, which can improve the support stability of the stabilizing seat on the top surface of the processing table. The fixed connection between the stabilizing seat and the reinforcement plate can improve the stability of the stabilizing seat, ensuring that the connection between the stabilizing seat and the processing table does not loosen and shake during long-term support on the top surface of the processing table. At the same time, the center of gravity between the stabilizing seat and the reinforcement plate is fixedly connected to the processing table, so that when the stabilizing seat is fixedly connected to the cross plate, the stability effect of the cross plate can be improved, avoiding loosening at both ends of the cross plate due to the unstable center of gravity of the stabilizing seat.

[0016] Compared with the prior art, the utility model provides a high-temperature and high-pressure downhole tool test clamping device, which has the following beneficial effects:

[0017] 1. The two ends of the downhole tool are respectively clamped by the clamping seat and the second clamping seat of the utility model, and the side positioning plates are clamped and limited by positioning bolts, ensuring that the downhole tool is clamped and fixed between the clamping seat and the second clamping seat without loosening. At the same time, the debris generated by the test fragmentation directly splashes into the stable frame and is received by the material receiving tray. After all the downhole tools are pressure-tested, the material receiving tray is directly pulled out from the front of the stable seat for cleaning, thereby effectively reducing the cleaning difficulty and keeping the downhole tool fixed during the compression test to avoid loosening and affecting the accuracy of the pressure test.

[0018] 2. The two ends of the stable seat of the utility model are fixedly connected to the processing table through the reinforcement seat, which can improve the support stability of the stable seat on the top surface of the processing table. The fixed connection between the stable seat and the reinforcing plate can improve the stability of the stable seat, ensuring that the stable seat does not loosen and shake at the connection with the processing table during long-term support on the top surface of the processing table. At the same time, the center of gravity between the stable seat and the reinforcing plate is fixedly connected to the processing table, so that when the stable seat is fixedly connected to the cross plate, the stability effect of the cross plate can be improved, avoiding loosening at both ends of the cross plate due to the unstable center of gravity of the stable seat.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-3 , a high-temperature and high-pressure downhole tool test clamping device, including a processing table 1. A stable seat 2 is arranged on the top surface of the processing table 1. A cross plate 3 is arranged between the stable seats 2. A hydraulic rod 4 is arranged on the bottom surface of the cross plate 3. A compaction plate 5 is arranged on the bottom surface of the hydraulic rod 4. Reinforcement seats 6 are arranged at both ends of the stable seat 2. A reinforcing plate 7 is arranged on the top surface of the reinforcement seat 6. A bearing seat 8 is arranged on the top surface of the processing table 1. A stable frame 9 is arranged on the top surface of the bearing seat 8. Support seats 10 are arranged at both ends of the stable frame 9. A clamping seat 11 is arranged on the top surface of the support seat 10. A positioning plate 12 is arranged on the front surface of the clamping seat 11. A material receiving tray 13 is arranged inside the stable frame 9. A support plate 14 is arranged on the top surface of the processing table 1. A reinforcing plate 15 is arranged on the bottom surface of the reinforcement seat 6.

[0025] Specifically, both ends of the top surface of the processing table 1 are fixedly connected to the stable seats 2 respectively, and the cross plate 3 is fixedly welded between the stable seats 2. Hydraulic pumps are fixedly connected to both ends of the inner wall of the cross plate 3 respectively, and the output end of the hydraulic pump is fixedly connected to the hydraulic rod 4. The compaction plate 5 is installed in a lifting manner on the bottom surface of the cross plate 3. The advantage is that the downhole tool is placed corresponding to the limiting grooves inside the clamping seat 11 respectively. After it is completely placed, the clamping seat 11 is rotated to be installed and fitted with the second clamping seat. After the positioning plates 12 on the front surfaces of the clamping seat 11 and the second clamping seat are closely fitted, they are reinforced by positioning bolts. It is ensured that during the process of the clamping seat 11 driving the second clamping seat to clamp and position the downhole tool, loosening between the clamping seat 11 and the second clamping seat is avoided, which may affect the normal clamping work of the downhole tool. During the process of using the hydraulic rod 4 to drive the compaction plate 5 for pressure testing, it is ensured that the clamping seat 11 and the second clamping seat can clamp and position the downhole tool, thereby effectively improving the fastening effect of the downhole tool and also improving the pressure measurement accuracy of the downhole tool. After the downhole tool is clamped and fixed, the hydraulic pump is started. The output end of the hydraulic pump drives the hydraulic rod 4 to move linearly to perform pressure testing on the downhole tool at the bottom end. During the testing process, the pressure sensor between the compaction plates 5 can record the pressure value borne by the downhole tool and transmit its test data signal to the control panel, which is convenient for the operator to directly record the data after the test, improving the pressure measurement accuracy of the downhole tool and also improving the use effect of the device. At the same time, the operation method is simple and convenient.

[0026] Specifically, the bottom surface of the hydraulic rod 4 is fixedly connected to a balance plate, and the bottom surface of the balance plate is fixedly connected to a weighted steel plate. The bottom surface of the weighted steel plate is fixedly connected to a compaction plate 5, and pressure sensors are fixedly connected between the compaction plates 5. The bottom surface of the compaction plate 5 corresponds to the stable frame 9. The advantages are that the support plate 14 and the bearing seat 8 can stably support the top stable frame 9. The support seats 10 at both ends of the stable frame 9 drive the clamping seats 11 to be fixedly connected to the stable seat 2, and there is a gap between the clamping seat 11 and the stable seat 2, ensuring that the clamping seat 11 can normally open and close to clamp and fix downhole tools. When the clamping seat 11 drives the support seat 10 to be respectively fixed to the processing table 1 and the stable seat 2, pressure measurement work is carried out, avoiding the deviation of the support seat 10 during the pressure test of downhole tools, which affects the accuracy of the test data of downhole tools. At the same time, the debris generated by the test fragmentation directly splashes into the stable frame 9 and is received by the material receiving tray 13. After all downhole tools are pressure-tested, the material receiving tray 13 is directly pulled out from the front of the stable seat 2 for cleaning. Thus, while effectively reducing the difficulty of debris cleaning, it ensures that the support seat 10 conducts pressure tests on downhole tools while being fixed, solves the problem of inconvenience in limiting and supporting downhole tools with different diameters, and is conducive to its popularization and use.

[0027] Specifically, a bearing seat 8 is fixedly connected between the stable frame 9 and the support plate 14. Support seats 10 are respectively fixedly connected to both ends of the stable frame 9, and the sides of the support seats 10 are respectively welded and fixed to the stable seat 2. The support plate 14 is fixedly installed on the bottom surfaces of the stable frame 9 and the support seats 10. The advantages are that the clamping seat 11 and the second clamping seat respectively clamp both ends of the downhole tool, and the side positioning plates 12 are clamped and limited by positioning bolts, ensuring that the clamping seat 11 and the second clamping seat do not loosen during the process of clamping and fixing the downhole tool. At the same time, the debris generated by the test fragmentation directly splashes into the stable frame 9 and is received by the material receiving tray 13. After all downhole tools are pressure-tested, the material receiving tray 13 is directly pulled out from the front of the stable seat 2 for cleaning. Thus, while effectively reducing the cleaning difficulty, it can also keep the downhole tool fixed during the compressive test, avoiding loosening and affecting the accuracy of the pressure test.

[0028] Specifically, the bottom surface of the clamping seat 11 is installed with the second clamping seat in an openable and closable manner, and the clamping seat 11 and the second clamping seat are connected by hinges. An installation groove is provided between the clamping seat 11 and the second clamping seat, and anti-slip sticker blocks are fixedly connected to the inner wall of the installation groove, and the installation grooves are symmetrically arranged. The advantages are that both ends of the stabilizing seat 2 are fixedly connected to the processing table 1 by the reinforcing seats 6, which can improve the support stability of the stabilizing seat 2 on the top surface of the processing table 1, and the fixed connection between the stabilizing seat 2 and the reinforcing plate 7 can improve the stability of the stabilizing seat 2, ensuring that there is no loosening and shaking at the connection between the stabilizing seat 2 and the processing table 1 during long-term support on the top surface of the processing table 1. At the same time, the center of gravity between the stabilizing seat 2 and the reinforcing plate 7 is fixedly connected to the processing table 1, so that when the stabilizing seats 2 are fixedly connected to the cross plate 3, the stabilizing effect of the cross plate 3 can be improved, and the loosening of both ends of the cross plate 3 caused by the unstable center of gravity of the stabilizing seat 2 can be avoided.

[0029] During use, place the downhole tools respectively in the limiting grooves inside the clamping seat 11. After placing them completely, rotate the clamping seat 11 to install and fit it corresponding to the second clamping seat. After the positioning plates 12 on the fronts of the clamping seat 11 and the second clamping seat are closely fitted, use positioning bolts for reinforcement. Ensure that during the process of the clamping seat 11 driving the second clamping seat to clamp and position the downhole tools, looseness between the clamping seat 11 and the second clamping seat is avoided, which may affect the normal clamping work of the downhole tools. During the process of using the hydraulic rod 4 to drive the compaction plate 5 for pressure testing, ensure that the clamping seat 11 and the second clamping seat can clamp and position the downhole tools, thereby effectively improving the fastening effect of the downhole tools. At the same time, the pressure measurement accuracy of the downhole tools can also be improved. After the downhole tools are clamped and fixed, start the hydraulic pump. The output end of the hydraulic pump drives the hydraulic rod 4 to move linearly and align with the downhole tool at the bottom for pressure testing. During the testing process, the pressure sensors between the compaction plates 5 can record the pressure values borne by the downhole tools and transmit the test data signals to the control panel, facilitating the operator to directly record the data after the test, improving the pressure measurement accuracy of the downhole tools, and at the same time improving the use effect of the device. At the same time, the operation method is simple and convenient. The support plate 14 and the bearing seat 8 can stably support the top stabilizing frame 9. The support seats 10 at both ends of the stabilizing frame 9 drive the clamping seat 11 to be fixedly connected to the stabilizing seat 2. And there is a gap between the clamping seat 11 and the stabilizing seat 2 to ensure that the clamping seat 11 can normally open and close to clamp and fix the downhole tools. When the clamping seat 11 drives the support seats 10 to be fixed to the processing table 1 and the stabilizing seat 2 respectively, pressure testing is carried out, avoiding the offset of the support seats 10 during the pressure testing of the downhole tools, which may affect the accuracy of the test data of the downhole tools. At the same time, the debris generated by the test fragmentation directly splashes into the stabilizing frame 9 and is received by the material receiving tray 13. After all the downhole tools are pressure-tested, directly pull out the material receiving tray 13 from the front of the stabilizing seat 2 for cleaning. Thereby effectively reducing the difficulty of debris cleaning and ensuring that the support seats 10 perform pressure testing on the downhole tools while being fixed, solving the problem that it is inconvenient to perform limit support on downhole tools with different diameters, which is conducive to its popularization and use.
