| Abstract: | This paper introduces a number of indoor physical simulating experiments with 215.9XHP 25-1 and 215.9 HPZ soft formation roller bits used in drilling Zizhong-sand and Jiayi-Limestone. The relationship of the torque and the penetration rates of the two types of bits varying with the bit weight and their average drive ratio are obtained through data collection and data processing system. and some important experimental data are provided for the improvement and design of the two types of soft formation roller bits. |
