Evaluation of Impregnated Diamond Bit based on Image Processing Technology

Abstract

Abstract-Impregnated diamond bit are widely used in very difficult formation drilling. In the drilling process, the diamond particles embedded in the impregnated diamond bit will inevitable wear, loss and adhesive wear. In this case, the bonding between diamond particles and matrix and the diamond performance play a very important role for the impregnated diamond bit life and drilling efficiency. This study analyzed and processed the collected diamond pictures by using image processing and numerical calculation to obtain the information on the dislodge and protrude of diamond particle and then get some conclusion on the retention capability of matrix on particle.
