Application
Medium Hard formation of high resist compression strength, and have hard interlayer. Such as argillite, sandstone, limestone and so on.
Feature
Cutter backing raised to minimize excessive depth of cut because of formation heterogeneity.Reduces cutter loading; minimize torque in transitional drilling.Minimizes cutter breakage and extends bit life.
Thermally stable polycrystalline (TSP) diamonds are placed on the leading edge of each blade.
Backreaming cutters. Strategic placement of cutters on the upside of each blade, to allow backreaming in tight spots, reduces the potential of ˇ°bit stickingˇ± while pulling out of the hole.
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 |
