Petroleum drilling pipe shocking and sliding wear tester

Abstract

The invention discloses an oil drilling rod shock slide abrasion tester, including the fixture system, the transmission system and the excitation system, in which the said fixture system clamping fixes the tubular specimen, and the one end of the said transmission system equips the rod specimen corresponding to the tubular specimen, and the said transmission system drives the rod specimen rotating with the axis, and the said excitation system provides radial shock to the said rod specimen, to drive the rod specimen shocks the tubular specimen fixed in the fixture system at the same time of rotating, to realize the composite shock slide friction, and through the friction, transmit the torque to the rod specimen. The invention overcomes the limitation of the existing abrasion testers, and it can realize rod friction and abrasion study of shock slide composite working conditions of controlled shock load type under the condition of multiphase cycle lubricating medium, and it can not only realize multiphase media cycle of adjustable flow and variable components, but also realize the complex impact of adjustable shock size, controllable wave-type.

Description

technical field [0001] The invention relates to a tribology test device, which mainly simulates the wear condition between the drill pipe joint and the casing in the deep well section in the process of oil drilling. Shaped steel pipe, during the drilling process, the drill pipe rotates around its own axis inside the casing and at the same time impacts 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, and provides a means for studying the wear of the casing and the drill pipe under this working condition. In addition, this testing machine can also be used to simulate other tribological systems in similar situations, especially in the field of tribological testing, impact-sliding composite working conditions or wear tests under medium conditions. Background technique [0002] At present, the test methods used to evaluate the wear resistance of oil drill pipe and casing...

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.
