Basical Specification | |
Size of bit | 8 1/2’’ |
Number of Blades | 5 |
Primary Cutter Size | 19mm |
Nozzle Qty. | 5NZ |
Thread Connection | 4 1/2 REG |
Operating Parameters | |
RPM (r/min) | 60~300 |
WOB(KN) | 20~110 |
Application | Medium-hard to hard formations with low compressive strength, such as hard shale, limestone, sand-stone, dolomite, hard gypsum, marble, etc. |
PDC cutters of different features are selected and bit profile design is potimized to suil different drilling applications in different formations to satisfy different requirement when drilling soft to medium hard formations.
Better wear resistance and higher strength of the bit are quaranteed in regard to material and struccture by using matrix body material with quality materials.
Enhanced gage design to improve the bits ability of gage protection.
Deep blade and long parabolic configuration,ensure optimal bottom hole flow pattern and anti-balling.
Anti-whirl design improves ROP and enhances the drilling stability.
Accoring to the requiremnets of customers,design and produce different bits.
