API 7-1 High Quality Standard Oilfield Equipment Petroleum Non Magnetic Drill Collar
Non‑Magnetic Drill Collar is a vital down‑hole drilling tool for well survey and measurement. Manufactured with special non‑magnetic alloy material, it avoids magnetic interference, ensuring accurate reading of MWD/LWD measuring instruments during directional drilling.
Produced in compliance with API 7‑1 standards, it features high tensile strength, great torsional resistance and outstanding anti‑corrosion performance. Premium material treatment improves wear resistance for harsh underground environments.
This drill collar is widely used for directional wells, horizontal wells and deviated wells. Various sizes and connection threads are available. It can be customized to match different drilling strings, offering reliable performance for oil‑gas directional drilling projects
