Problems solved by technology

[0003] In the prior art, the device used to test the tensile and torsional strength of downhole tools has a complicated structure and cannot simulate the downhole environment well.
For example, the test device tests the tensile and torsional properties separately, and cannot test the tensile and torsional properties at the same time
However, the actual work of downhole tools is to bear axial force and torque at the same time, which will affect the test accuracy

Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing.

[0028] figure 1 A testing device 100 according to the invention is shown. Such as figure 1 As shown, the test device 100 includes a base 1 , a first support frame 2 , a second support frame 3 , a first connector 4 and a second connector 5 . Wherein, the base 1 is in the shape of a plate extending horizontally, and mainly plays the role of foundation support. The first supporting frame 2 is configured to be vertically arranged on the base 1 . The second support frame 3 is also vertically arranged on the base 1, and is transverse to the first support frame 2 ( figure 1 in the roughly left-right direction) for the purpose of jointly supporting the downhole tool 200 to be tested. The first connecting head 4 is arranged on the first support frame 2 and configured to be able to rotate relative to the first support frame 2 . The second connecting head 5 is fixedly arranged o...

Abstract

The invention provides a testing device for a downhole tool. The testing device comprises a plate-shaped base which extends horizontally; a first supporting frame, vertically arranged on the base; a second supporting frame, vertically arranged on the base, and the second supporting frame and the first supporting frame being distributed oppositely; a first connector, which is arranged on the first supporting frame and can rotate relative to the first supporting frame; and a second connecting head, fixedly arranged on the second supporting frame, the second connecting head and the first connecting head can be distributed oppositely, and the first supporting frame can drive the first connecting head to move transversely relative to the second supporting frame so as to increase or shorten the distance between the first connecting head and the second connecting head. According to the testing device, the axial force and the torque are applied to the downhole tool to be measured at the same time, so that the actual use process of the downhole tool is simulated more truly, and the safety performance of the downhole tool is evaluated more accurately.

Description

technical field [0001] The invention belongs to the technical field of petroleum and natural gas industry machinery, and in particular relates to a testing device for downhole tools. Background technique [0002] With the continuous deepening of oil and gas development, drilling technology has also made great progress, and various drilling speed-increasing tools have emerged. After the drilling speed-increasing tool is put into the well, if it breaks, it will cause falling objects in the well, which will cause great losses to the construction. Therefore, various tests need to be carried out before the tool entry test, including tool performance test, tool safety test, etc. The tool performance test is to verify whether the function of the tool meets the design requirements, and the tool safety test refers to testing the tensile and torsional performance of the tool to verify whether it meets the requirements for entering the well. [0003] In the prior art, the device for ...
