Body Material of PDC drill bits:

Tungsten carbide sintered matrix body \ steel body


Application fields of PDC drill bits:

Widely used for petroleum, natural Gas Exploration development

1. Suitable for the drilling of the deep well ,ultra deep well and the slim hole, 16 mm main cutting tooth diameter, 5 blades, medium parabolic profile crown, medium cutter density ,which can ensure the ROP in the medium hard formation, and guarantee the use life in abrasive formation.

2. The whole bit uses the best cutter with strict inspection and testing, which can ensure the wear resistance and impact resistance, and with the methods of finite element analysis, it can optimize the structure of the drill bit , increasing its strength , and make it safer in using and maximize gauge strength with diamond gauge technology .

3.with the optimized hydraulic design and new nozzle layout design, it can remove the rock debris from the well more effectively , improve the cutters’ cooling effect ,and extend the working hours in the well.

4. Suitable for abrasive medium hard formation with the high anti-stress, Such as limestone, shale, anhydrite, tuffaceous rocks, calcareous sandstone etc.
