Features
Provide multiple advantages in interbeded lithology.
Enhanced bit stability for BHA shock and vibration mitigation.
Increase cleaning and reduce balling.
Superior PDC cutter technology made a perfect performance on impact strength resistance and abrasive resistance.
Dual row cutter extend the aggressiveness and durability.
The FEA software for the cutters distribution and layout made the drilling more efficient and reduce NPT.
Optimize the angle of the cutter in both axial and radial by FBS(force balance analyze) software resulting in stronger aggressive and more durability of the bit.
DOC(depth of cutters) was calculated and optimized by a series experiences of the bit,made the cutter penetrate the formations more rationally.
Effectively improve the stability and ROP of the bit by spiral blade.
