Application
Hard formation of high abrasiveness, Such as hard limestone, dolomite, blaize, flint and so on.
Feature
Balanced force design of spiral blades endows the bits with good orientation,little radial vibration as well as ability to increase cutter placement
The reasonable layout of patented PDC cutters in various structures at different locations endows the bits with strong aggressiveness and anti-abrasiveness
Strong aggressiveness allows the bits high ROP
The simulation technology of dynamic flow field are used in hydraulic design to optimize down-hole flow field,beneficial to improve clearance speed and anti-balling simultaneously
