Design character:

■Spiral blades increase contact area between PDCbit and well wall to keep drilling stably, to prolonglifespan of PDC bits.

■Adopting CFD emulational technology to calculateto optimize PDC bit, then reduce possibility of heavybreaking and wearing of bit.

■Special design of back-rake angles will decreasetorque on bit, increase bit aggressiveness, improveefficiency of ROP.

■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.
