Abstract

Abstract

Based on summarizing and analyzing the PDC performance testing methods at home and abroad, the wear ratio, impact toughness and thermal stability of five PDC products of different manufacturers were tested, evaluated and optimized by conventional testing methods. The actual drilling performance test was carried out on the micro drilling test platform with the two selected PDC bits. The results show that the drilling efficiency attenuation coefficient and the average peak value of drilling efficiency are used to evaluate the PDC real drilling performance. The method is scientific, the data is accurate and the result is practical. It can be used as the reference basis for selection of PDC bit teeth for coal mine drilling.
