In order to solve the problems of severe wear of cutting teeth and less bit footage of ordinary PDC bit in gravel stratum with strong abrasiveness and impact in the lower stratum of Dong ying North Zone. This paper introduces a design method of impact resistant PDC bit, and carries out simulation analysis, indoor experiment and field test on this design method. The test results prove that the designed impact resistant PDC bit has the advantages of high penetration rate and more footage, and verify the rationality and feasibility of the bit design.
