Anti-sliding card PDC drill bit developed

Shengli oilfield drilling home an anti-sliding PDC drill bit developed and national invention patents. This slide-proof card built-in hydraulic impact mechanism of PDC bit, rock-breaking power of increase the PDC drill bits, drilling speed.

Sticking slippery twist of PDC bit combination of punching tools and PDC drill bits, use of integrated design, PDC bits original "shearing" breaking into "mechanical shearing + shock" rock-breaking way. Compared to the traditional twisted combination of punching tools and PDC drill bits, sticking slide PDC drill bit length shorter, more efficient, more secure and reliable.
