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 addresses the requirements of various specialized procedures, minimizing tool change frequency during well operations and 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 a single-trip core length of up to 9.5 meters with a core recovery rate exceeding 98%. This significantly enhances geological sampling efficiency and data quality.
An eccentric, twin-body while-drilling reamer with a pilot-hole-to-reaming-diameter ratio of approximately 1.2-1.5. Featuring an automated mechanical centering mechanism, it efficiently enlarges wellbore diameter during drilling operations, enabling complete reaming in a single run.
Integrating multiple high-wear-resistant components including diamond-composite teeth, gradient cemented carbide, and natural diamond matrices, these milling shoes deliver exceptional performance. They are ideally suited for 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
