Features

• 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.
• Increased cleaning, cooling, and cuttings evacuation with available hydraulic flows; high flow rates with minimal increase in pump pressure, and reduced risk a bit balling.
