Petroleum drilling pipe shocking and sliding wear tester

Abstract

The invention discloses an impact sliding wear tester for oil drilling rods and tubes, which includes a clamping system, a transmission system and an excitation system, wherein the clamping system fixedly clamps a tubular test piece, and one end of the transmission system is The tubular test piece should be equipped with a rod-shaped test piece, the transmission system drives the rod-shaped test piece to rotate around the axis, and the vibration excitation system provides radial impact force to the rod-shaped test piece to drive the rod-shaped test piece. The rod-shaped test piece impacts the tubular test piece fixed on the clamping system while rotating, realizing compound impact-sliding friction, and the torque is transmitted to the rod-shaped test piece through friction. The invention overcomes the defects of the existing wear testing machine, and can realize the rod-tube friction and wear research of the impact-sliding compound working condition of the controllable impact loading type under the condition of multi-phase circulating lubricating medium. It can not only realize the adjustable flow rate and the variable composition Variable multi-phase medium circulation, and can realize complex impact with adjustable impact size and controllable wave type.

Description

technical field [0001] The invention relates to a tribology test device, which is used for simulating wear tests in the field of tribology tests under combined shock-sliding working conditions or medium conditions, in particular to a drill pipe joint and casing in a deep well section in the process of simulating oil drilling The oil drilling pipe impact sliding wear test machine for the wear condition between them provides a means for studying the wear of casing and drill pipe under this working condition. Background technique [0002] At present, the test methods used to evaluate the wear resistance of oil drill pipe and casing materials under the conditions of impact-sliding composite working conditions or media mainly include reciprocating impact wear using a pin-on-disk tester with a vibration device, a cam or a crankshaft drive. Testing machine, pendulum-loaded pulsating impact wear testing machine and various lubrication testers. [0003] (1) Principle and characteris...

Problems solved by technology

[0013] The technical problem to be solved by the present invention is to provide a special impact-sliding wear tester, aiming at the fact that the current wear tester cannot meet the requirements of studying the combined impact-slide wear test between oil drilling drill pipe and casing under the condition of circulating medium. It can be used to systematically study the impact-sliding composite friction and wear of different large-size materials on oil drilling pipes and casings under various medium circulation conditions, and provide a new test method for oil drilling pipes and casing wear research.
