Problems solved by technology

[0011] The Maurer testing machine has a good detection system, but the testing machine can only simulate the sliding wear condition under the action of static load, and cannot carry out relevant research on the impact-sliding composite wear condition caused by lateral vibration in the lower part of deep wells and ultra-deep wells

Embodiment Construction

[0046] The specific implementation manner of the present invention will be further described in detail below in conjunction with the drawings and specific examples.

[0047] Such as Figure 1 to Figure 4 As shown, the present invention proposes a sliding table type casing wear tester, which includes a transmission system 1, an excitation system 2, a clamping system 3 and a frame 5, and the rotating transmission shaft 110 of the transmission system 1 is fixedly clamped with the first A test piece, the clamping system 3 is equipped with a second test piece corresponding to the first test piece, the transmission system 1 drives the first test piece to rotate around the axis, and the frame 5 is provided with at least one sliding platform. The transmission system 1 is arranged on the sliding platform, and the vibration excitation system 3 can drive the sliding platform to vibrate up and down, that is, the vibration excitation system 2 can drive the transmission system to vibrate up...

Abstract

The invention is a sliding way sleeve abrasion testing machine, which comprises a transmission system, an excitation system, a clamping system and a rack. A first test piece is fixed and clamped on a rotating transmission shaft of the transmission system; a second test piece is arranged corresponding to the first test piece on the clamping system and the transmission system drives the first test piece to rotate around the axis. The rack is provided with at least one sliding platform and the transmission system is arranged on the sliding platform. The excitation system can drive the sliding platform to vibrate up and down to drive the first test piece to impulse the second test piece while rotating. The testing machine overcomes the disadvantage of the prior abrasion testing machine which is incapable of satisfying the requirement on studying the impulse and sliding composite abrasion test between petroleum the drilling rod and the sleeve under the conditions of circulating medium and can perform systematic investigation on the impulse and sliding composite abrasion of various materials of large dimension between the petroleum the drilling rod and the sleeve.

Description

technical field [0001] The invention relates to a tribology test device, which mainly simulates the wear condition between the drill pipe (mainly the drill pipe joint) and the casing in the deep well section during the oil drilling process. For a circular steel pipe with a certain wall thickness, during the actual drilling process, the drill pipe rotates around its own axis inside the casing, and at the same time, it is accompanied by the impact on the inner wall of the casing in the radial direction. This testing machine is used to simulate the relative movement between the drill pipe and the casing. On the one hand, it provides a test method for studying the wear mechanism of the casing and the drill pipe under this working condition. On the other hand, it can prevent the wear of the drill pipe casing. Technology provides the means of evaluation. In addition, when the excitation system is not turned on, this testing machine can carry out the sliding wear test of oil casing ...
