The XS series represents a specialized drilling bit lineup engineered for unconventional drilling operations. This comprehensive system integrates multiple functional modules including core drilling, while-drilling reaming, and milling capabilities. A single XS-series kit accommodates diverse specialized procedures, minimizing tool change frequency during well operations while delivering professional, high-performance solutions for complex, non-standard well conditions.
Equipped with high-performance core bits featuring Sichuan-style standard connections, this module achieves single-trip core lengths up to 9.5 meters with core recovery rates exceeding 98%. This significantly enhances geological sampling efficiency and data accuracy.
Features an eccentric, twin-body while-drilling reamer with a pilot-hole-to-reaming-diameter ratio of approximately 1.2-1.5. The integrated automated mechanical centering mechanism enables wellbore diameter enlargement during drilling operations, facilitating complete reaming in a single run.
Incorporates multiple high-wear-resistant components including diamond-composite teeth, gradient cemented carbide, and natural diamond matrices. These milling shoes deliver exceptional performance in complex downhole obstruction-clearing operations such as casing milling and debris milling.
This specialized drilling system provides tailored solutions for a wide range of non-standard drilling challenges, including:
- Core sampling operations
- While-drilling reaming applications
- Casing milling procedures
- Debris milling operations
- Other unconventional special drilling operations
