SV series: Six point position stabilization motor bit,
Cutting structure:
the durability of premium tungsten carbide inserts is improved with new formulas and new techniques.
Gauge structure:
Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide
inserts and hardfacing on the shirttail increases gauges holding capacity and bearing life.
Bearing structure
high precision journal bearing with two thrust faces, balls lock the cone. hardfaced head bearing surface. Cone bearing inlaid with friction-reducing
alloy and then silver-plated, Abrasion resistance and seizure resistance of the bearing are improved, and suitable for high rotary speed.
Seal and lubrication
Advanced metal face seal lowers seal frictional force and overral seal torque and improves seal life.
the pressure compensator system and advanced grease can greatly the lubricating reliablility.
Six-point position stablization structure
the bit leg is designed with specific integrated stablization structure, which provides near six-point contact with borehole wall for the bit.
this new feature gives the bit unequaled stalility which greatly reduces bit vibration protects the cutting structure from damaging blows and keeps
good borehole quality, the thickened nozzle wall can protect hydraulic system from wear and fluid erosion.
Production application
it is suitable for downhole motor and high speed applications, and is the ideal selection for drilling directional and horizontal wells.
