FEATURE | ||||
Suitable for soft formations, such as clay rock, sandstone, shaping mudstone, etc. Deep blade with long parabolic shape structure and anti swirl design, Maximizing the mechanical drilling speed and stability of the drill bit. Welding high-performance wear-resistant materials on the surface of the blade, Enhance the wear resistance and erosion resistance of the bit. Double row tooth,Reasonably configure high-quality PDC composite sheets, 0ptimize the tooth structure, improve the aggressiveness and abrasion resistance of drill bits Strengthening gauge with PDC composite sheets,Reduce the wear and tear of rocks on diameter preservation. Increase the wear resistance and stability of gauge, improve the service life of drill bits. Hydraulic structure optimization. Flow field design at the bottom of the well is beneficial for the migration of rock debris and the prevention of mud bags. |
