Beijing Superior Drilling Equipment Co.,Ltd products

Cutting Structure: Offset crested scoop compacts in inner row, wedge compacts in outer row and inequable spaced compacts arrangement. The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit. Gauge Structure: Multiple gouge protection with gauge trimmers on the heel of cone, tungsten carbides inserts and hard-facing on the shirttail increases gauge holding capability and bearing life.

MatrixPDC bit with six blades of parabola crown profile and with medium cutterdensity. Spiralgauge protection design reduces vibration severity. Withinterchangeable screw nozzles. Asymmetricalblades arrangement and special load-balanced cutter arrangement design improvebit stability and therefore higher ROP. Non-planeinterfaced diamond/carbide cutters absorb effectively high stress and minimizecutter fracturing and wearing. Bothtilted and cauterized nozzles design improves bit cleaning and prevents bitballing, thus to improve ROP. Canbe used on rotary or down hole motor drilling. Suitablefor medium to hard formation. HighHIS is recommended.

Reaming with motor is prohibited. Slurry is recommended as drilling fluid. Flow rate of pump should not be lower than 600L/M, or the motor cannot be driven, or be locked in drilling process. A new or idle motor should be rotated clockwise at least 2 rounds with a tong before working with a pump. After use, the motor should be cleaned internally. Rotate the drive axle to remove the residual fluid. Drive axle of this motor is lubricated open, hence   fluid leak is tolerated.
