Experiment Research on Influence of Mud Density to Wear Resistance of TP140 Casing

Abstract:

Due to complex down-hole conditions and longer drilling time, there are serious casing wear in deep and ultra deep well. It is necessary to carry out a deeper research of the casing wear. Theory of casing wear and prediction method are not perfect in deep well and ultra deep well .The purpose of this paper is to obtain the wear efficiency and friction coefficient which is used to predict wear of the TP140 casing in down hole. A block-ring casing wear tester is specially designed and produced. The wear efficiency and coefficient of friction which is used to predict wear of TP140 casing in different density polysulfide water-based mud is obtained. The influence of the mud density on the TP140 casing wear resistance is analyzed. It is found that the larger mud density, the bigger casing wear efficiency and the friction coefficient.
