Drilling Technology Research Institute, Shengli Petroleum Administrative Bureau, Dongying 257017, China) Abstract: The reasonable utilization of polycrystalline diamond compact(PDC) bit cutters has an impact relation with exerting its technical advantage. At first, a brief review of drillability mensuration and grade criterion of PDC bit cutters in China is introduced. Secondly, a brief introduction to laboratory test, analysis and processing of experimental data, some qualitative and quantitative conclusions are recited in detail. Finally, from the practice, some reasonable essential techniques and fundamental for choosing and using PDC bit cutters are brought forward based on the collective function of cutting rock, inosculation between rock and cutters , and the parameter of drilling technology. Key words: polycrystalline diamond compact; bit
