8 1/2 XS-TJ 416(24011) Size PDC Drill Bit with GI Cutter Grade and 4-1/2REG API Connection for Oil and Gas Drilling
The XS series is a specialized drilling bit lineup engineered for unconventional drilling operations. Featuring multiple functional modules including core drilling, while-drilling reaming, and milling, a single XS-series kit can meet the requirements of various specialized procedures. This reduces tool change frequency during well operations and serves as a professional, high-performance solution 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 and a core recovery rate exceeding 98%, significantly enhancing geological sampling efficiency.
An eccentric, twin-body while-drilling reamer with a pilot-hole-to-reaming-diameter ratio of approximately 1.2-1.5. Equipped with an automated mechanical centering mechanism, it can enlarge the wellbore diameter during drilling, enabling complete reaming in a single run.
By integrating multiple high-wear-resistant components including diamond-composite teeth, gradient cemented carbide, and natural diamond matrices, these milling shoes deliver exceptional milling performance. They are well-suited for complex downhole obstruction-clearing operations such as casing milling and debris milling.
Core sampling, while-drilling reaming, casing milling, and debris milling—among other unconventional special operations—provide tailored solutions for a wide range of non-standard drilling challenges.
