Design character:

■Special design of back-rake angles will decrease torque on bit, increase bit aggressiveness, improve efficiency of ROP.

■Adopting CFD emulational technology to calculate to optimize PDC bit, then reduce possibility of heavy breaking and wearing of bit.

■Special gauge design has more cutters placed on gauge to prolong life time of PDC bit in high abrasive formation, to avoid diameter shrinkage for gauge wearing.

■Suit for well drilling in low compressive strength, even texture soft-medium rock formation. Such as wake shale, density marlstone, strong batt, wake sandstone, limestone, and soft gravel, etc.
