8 1/2″WS319SG(215.9mm)

Design character:

■Spiral blades increase contact area between PDC bit and well wall to keep drilling stably, to prolong lifespan of PDC bits.

■These back redressings at the base of gauge avoid difficult of pulling PDC bits our of hole in unconsolidated formation, and trim wall of well.

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

■Suit for well drilling in low compressive strength, high drillability soft rock formation. Such as soft limestone, chalk, halite, gypsum, anthracite, brocken sandstone, and rocky soil,etc.
