Embodiment Construction

[0040] The specific implementation manner of the present invention will be further described in detail below in conjunction with the drawings and specific examples.

[0041]As shown in the figure, the oil drilling rod and pipe impact sliding wear test machine proposed by the present invention includes a clamping system 1, a transmission system 2 and an excitation system 3, wherein the clamping system 1 fixedly clamps the first test piece, One end of the transmission system 2 is equipped with a second test piece corresponding to the first test piece, the transmission system 2 drives the second test piece to rotate around the axis, and the vibration excitation system 3 is directed toward the second test piece. A radial impact force is provided to drive the second test piece to impact the first test piece fixed on the clamping system 1 while rotating, and transmit the torque to the second test piece through friction.

[0042] In a specific embodiment of the present invention, the...

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...
