The Experimental Research of P110 Casing Wear-Resisting Property in Oil Base Mud

Abstract:

The contact and slide under high pressure between casing and tool joint leads to wear of the casing inner surface in cemented well. The reduced collapse and burst strength of worn casing threats to the safety of oil and gas well. In order to calculate the wear depth and residual strength of the casing wear, the wear efficiency and friction coefficient is measured in the different wear time, the contact force and the rotating speed. The wear efficiency is in proportion to the contact force and the rotating speed. The wear efficiency of P110 casing change from 2 to 4×10^-13 1/Pa. Friction coefficient reaches maximum value under certain contact force and rotating speed. The rotating speed has less influence on the wear mechanism of casing, while the contact force play a greater influence on the wear mechanism.
