8 1/2 XD S 6169 BS(24054) Size PDC Drill Bit with GI Cutter Grade and Ultra-Short Body Design for Directional Drilling

The XD series drill bits are directional drilling tools engineered to meet the rigorous demands of various directional well applications, including coalbed methane drainage directional wells and oil horizontal wells. Incorporating advanced drill-bit design concepts with specialized structural and material optimizations, the XD series delivers highly efficient rock-breaking performance even under complex wellbore trajectory conditions.

• Suitable for use with rotary steerable systems to increase build rates, or with screw motors to enhance directional drilling efficiency
• Ultra-short body design reduces effective make-up length by 40% compared to conventional drill bits, significantly improving deviation-control capability
• Unique detent-tooth design ensures excellent tool-face stability even under enhanced weight-on-bit during directional sliding operations
• Maximum build rate for bent subs: ≥30°/30 m
• Maximum build rate for rotary steerable systems: ≥15°/30 m

The XD directional series is specifically designed for critical drilling sections such as build-up and horizontal sections of directional wells. It can be effectively used in conjunction with downhole screw motors and other directional tools. In demanding applications including coal mine gas drainage boreholes and highly challenging long-reach wells, this drill bit series has consistently demonstrated outstanding performance, achieving superior single-trip penetration and rapid rates of penetration.
