Abstract

The invention discloses an axial displacement sensor clamping device, and the device is used for clamping an axial displacement sensor which is used for a pipe test of a petroleum thermal production well. The device comprises a guide rod (3), a lower support (2), a horizontal adjustment part (7), and a locking apparatus. One end of the guide rod (3) is fixed at the upper part of a test piece, andthe other end of the guide rod is connected with a displacement sensor (4). The lower support (2) is fixed at the lower part of the test piece, and extends towards a side to form a chute. The horizontal adjustment part (7) can slide in the chute, and is fixedly connected with a measurement core rod (6) in a measurement hole of the displacement sensor (4). The locking apparatus is used for fixing the horizontal adjustment part (7) after the horizontal adjustment part (7) slides in place. Through the adjustment of the parallelism of the displacement sensor and a sample, the device guarantees that the measurement direction of the displacement sensor is consistent with the axial of the sample.

Description

technical field [0001] The invention belongs to the field of pipe material testing in petroleum thermal recovery wells, and is used for clamping an axial displacement sensor in the thermal recovery well pipe test of petroleum, in particular to a clamping device for axial displacement sensors. Background technique [0002] In the oil thermal recovery well pipe test, according to the requirements of the TWCCEP standard, it is necessary to conduct a thermal cycle test on the sample. During the heating process of the sample, it is necessary to use a high-precision displacement sensor to measure the deformation of the sample and control it through the deformation. During the whole process, the feedback stability of the displacement sensor is extremely demanding, generally within 0.02mm. Due to thermal expansion and contraction of the sample during thermal cycling, it poses a problem for effective clamping of the sensor. Contents of the invention [0003] In order to solve the ...
