TorkBuster is connected above the PDC bit, driven by drilling fluid, the internal rotating hammer generates high-frequency torsional impacts in the circumferential direction and tr…

The roller bit core barrel uses high carbon steel and a special bit Angle to maintain drilling strength and efficiency.
-
Higher ROP potential than roller cone drill bits Compared to roller cone bits, hybrid drill bits can increase ROP, requiring less weight on bit and minimizing bit bounce.

The PDC hole opener is designed for use in soft clays and shales to medium-hard shales and limestones and is particularly effective in sticky formations where balling problems are …

Fast drilling in the soft formation,limited by the length of the bit gauge,the bore hole trajectory is irregular,this situation caused bit bouncing, high torque and drag .
