Description

Technical Field

[0001] The present invention relates to the technical field of downhole detection tools, and in particular to an automated downhole temperature and pressure testing tool. Background Art

[0002] The detection of downhole oil pressure and temperature is an essential step in the oil extraction process. Downhole pressure and temperature directly affect the efficiency of extraction and the safety of the operation. By detecting downhole pressure and temperature, it can assist extraction personnel in analyzing and judging downhole information, and then formulate corresponding extraction plans.

[0003] In the prior art, when measuring the temperature and pressure downhole, a test tool is placed in the well and the pressure and temperature are measured by setting a pressure measuring hole. However, this measurement method requires oil to enter the test tool.

[0037] The buffer mechanism includes a positioning rod 209, which is slidably installed in the corresponding slide groove 2. The positioning rod 209 is slidably connected to the support tube 101. A spring 203 is provided in the inner cavity of the positioning rod 209.

A positioning head 202 is fixedly installed on the end of the positioning rod 209 away from the position adjustment rod 208, and anti-slip grooves are provided on the positioning head 202.

[0038] A conical tube 103 is installed at the lower end of the support tube 101. The conical tube 103 is an inverted cone to reduce the resistance when entering the well. The support tube 101 is provided with installation groove 1, installation groove 2, installation groove 3, installation groove 4, installation groove 5 and installation groove 6 from top to bottom, and installation groove 1, installation groove 2, installation groove 3, installation groove 4, installation groove 5 and installation groove 6 are all evenly spaced apart in a circular shape.

[0039] The working principle of the present invention is: using external lifting equipment to lift the test tool to the well to be tested through the lifting ring 102, because the tapered tube 103 is an inverted cone, the resistance when entering the well is reduced.

[0040] When the positioning mechanism and the buffer mechanism are working: the output shaft of the motor 206 drives the rotating plate 207 to rotate, the rotating plate 207 drives the position adjustment rod 208 to move through the arc groove, the position adjustment rod 208 drives the positioning rod 209 to move through the spring 1 203, and then drives the positioning head 202 to move, so that the multiple positioning heads 202 are opened. If the downhole pipe is deformed or there is foreign matter on the well wall and blocks part of the positioning head 202, the position adjustment rod 208 moves in the inner cavity of the positioning rod 209, and the spring 1 203 is compressed, thereby avoiding the deformation of the downhole pipe or the foreign matter on the well wall causing the detection tool to be damaged. The problem of being unable to perform positioning support is solved by improving the stability of the positioning support for the test tool. At the same time, since the positioning head 202 and the positioning rod 209 can be retracted, wells of different sizes can be tested, and it is also convenient for the retraction and deployment of the test tool, that is, the positioning head 202 and the positioning rod 209 are retracted when placed, and the positioning head 202 and the positioning rod 209 are opened when positioning support is needed. At the same time, by setting up two sets of upper and lower positioning components, the stability of the test tool can be guaranteed, which solves the problem in the prior art that the test tool is displaced during the detection process and affects the detection results because only one end is fixed.

[0041] When the position adjustment mechanism and the detection mechanism are working: after the test tool is lowered into the well, it is positioned and supported by the positioning support assembly, and the piston rod of the electric cylinder 409 drives the lifting frame 407 to slide on the guide rod 410. When the lifting frame 407 moves, it drives the connecting rod 1 405 to move through the connecting rod 2 406. The connecting rod 1 405 drives the detection head 402 to move through the spring 2 403. It moves a set distance according to the size of the downhole pipeline (obtain the downhole pipeline information in advance). The moving distance is greater than the size of the pipeline. When moving, multiple detection heads 402 are moved to the pipeline. Due to the obstruction of the pipeline, the detection head 402 cannot continue to move. The connecting rod 1 405 is in the detection The detection head 402 moves in the inner cavity, the spring 2 403 is compressed, and at the same time, the detection head 402 drives the displacement detection shaft on the displacement sensor 408 to move through the displacement rod 404, and the displacement is detected by the displacement sensor 408. If the pipeline is deformed or there is a foreign object, the displacement at the deformed or foreign object location is different from other normal displacements, and it is also inconsistent with the size information of the pipeline, which means that the pipeline has been deformed, so that it can be detected whether the pipeline is deformed, which improves the diversity of downhole detection parameters. At the same time, the detection process is simple and fast, the detection results are relatively accurate, and the status of the downhole pipeline can be obtained in time, ensuring the safety of downhole pipeline operation.

[0042] When the temperature detection component is working, the temperature downhole is detected by the detection heads of the multiple temperature sensors 301 distributed up and down, and the temperature downhole at different depths can be detected.

[0043] When the pressure detection component is working: when the pressure detection component descends into the well, when the detection rod 501 is subjected to pressure, the detection rod 501 transmits the pressure to the force transmission head 505 through the connecting tube 503, and the force transmission head 505 transmits the pressure to the pressure tester 506, thereby detecting the downhole pressure. At the same time, the stability of the pressure tester 506 can be ensured by the two shock-absorbing sleeves 303, thereby improving the service life. Through this pressure detection component, it is possible to avoid the problem of oil accumulation in the test tool due to oil entering the test tool during the detection process, which makes it inconvenient to clean up later. The service life and stability of the test tool are improved, and it is also convenient for the maintenance of the test tool in the later stage, reducing the workload of the maintenance personnel.
