Xingtong Drill Bit 8 1/2 XD S 5165 BS(24061)
Product Positioning
The XD series drill bits are advanced 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 the latest drill-bit design concepts and featuring specialized optimization in both structure and materials, the XD series delivers highly efficient rock-breaking performance even under complex wellbore trajectory conditions.
Key Applications & Features
Rotary & Directional Systems
Suitable for use with rotary steerable systems to increase build rates, or with screw motors to enhance directional drilling efficiency.
Compact Design
Ultra-short body design reduces effective make-up length by 40% compared to conventional drill bits, significantly enhancing deviation-control capability.
Stable Performance
Unique detent-tooth design ensures excellent tool-face stability even under enhanced weight-on-bit during directional sliding operations.
Maximum Build Rates
Maximum build rate for bent subs: ≥30°/30 m | Maximum build rate for rotary steerable systems: ≥15°/30 m
Operating Conditions
The XD directional series is specifically designed for critical drilling sections such as the 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 such as coal mine gas drainage boreholes and highly challenging, long-reach wells, this drill bit series has consistently delivered outstanding performance, achieving superior single-trip penetration and rapid rates of penetration.
