Application
Soft formation of low resist compression strength, high drillability, such as shale, clay, rock salt, cotton rock 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
- The PX feature places thermally stable diamond inserts (TSP) on the gauge to maximize gauge retention and extend bit life.
- Bit design is available with premium fixed cutters and tungsten carbide rock drill bit for improved thermal stability in harder, more abrasive formations, resulting in greater wear resistance.
