Study of Resistance to Wear of P110 Casing Down-Hole in Water Based Mud

Abstract:

The operation of drilling well leads to casing wear to some degree in cased well. The reduced strength of worn casing threats to the safety of well test and completion. In order to calculate casing wear depth and prevent 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 increases with the contact force and the rotating speed. And the bigger the rotating speed, the bigger the friction coefficient. The wear efficiency of P110 casing is change from 2 to 8×10-13 1/Pa. The rotating speed has less influence on the wear efficient. So it is reasonable that the wear efficiency model is adopted to calculate the wear degree of P110 casing.
