Application
Soft and medium soft formation of low resist compression strength, or hard interlayer, such as anhydrite, cotton rock, sandstone and so on.
Features
Strategic placement of cutters on the upside of each blade, to allow backreaming in tight spots, reduces the potential of bit sticking while pulling out of the hole. More aggressive side-cutting.
The side ball make sure the stable drilling even in high ROP.
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.
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.
