Application
Soft to medium hard formation with low compre-ssive strength with hard layer.Such as caly, sands-tone, tuff, etc.
PDC cutters of different features are selected and bit profile design is optimized to suit different drilling applications in different formations to satisfy different requirement when drilling soft to medium hard formations.
Better wear resistance and higher strengthe of the bit are quaranteed in regard to material and structure by using matrix body meterial with quality materials.
Enhanced gage design to improve the bit’s 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 enhaces the drilling stability.
According to the requirements of customers,design and produce different bits.
