6″WS513R(152.4mm)

Design character:

The back row cutters help to cut rocks, protect matrix, prolong lifetime and deduct cost of PDC bit

Wide flow design is adopted to pull drilling mud out of hole smoothly. This design is suit for fast drilling.

This design increases contact area between PDC bit and well wall, improves wear resistance of gauge. This kind of PDC bit performs stably in horizontal drilling.

The PDC bits are widely used in Changqing oilfield for horizontal drilling. Each bit can drill 600 to 800 meters depth. Speed of horizontal drilling can reach 20 to 25m/h.
