FEATURE | ||||
Suitable for medium hard formations with high compressive strength and abrasive properties,such as limestone, hard gypsum dolomite, sandstone,etc. Deep spiral blade wing,short parabolic shape structure,anti rotation 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 structure,Reasonably configure high-quality PDC composite sheets, Optimizing the tooth structure to Improve the attack and abrasion resistance of the drill bit. Using PDC composite sheets to lengthen gauge, lmprove the lateral stability and compressive strength of the drill bit, reduce lateral offset and improve wellbore quality. Hydraulic structure optimization,Flow field design at the bottom of the well is beneficial for the migration ofrock debris and the prevention of mud bags. |
