Well Abandonment弃井服务
Deepwater P&A built on our patented outside-suspension tool: wellhead cutting, cement plug placement and wellhead recovery in a single trip — typically saving 15–20 hours of rig time per deepwater well. Severs 20″×30″ and 20″×36″ wellheads, plus one-trip 9-5/8″ / 13-3/8″ casing cut & pull.
以专利深水外悬挂弃井工具为核心：一趟管柱完成井口切割、注水泥塞与井口头回收，单井通常节省钻机时间 15–20 小时。可切割回收 20″×30″ 与 20″×36″ 井口，并提供 9-5/8″ / 13-3/8″ 套管一趟式切割回收。
China deepwater P&A record: 2,083 m (2024).

Continuous Circulation连续循环系统
Valve-type continuous circulation drilling system, now in its fifth generation. Rated 7,500 psi; circulation subs rated to 500 t tension and 100,000 ft·lbs torque. Keeps bottomhole pressure steady through connections, holding ECD fluctuation under 5% — for demanding narrow-window, ERD, MPD and air-drilling projects.
阀式连续循环钻井系统，现已迭代至第五代。系统额定 7,500 psi，循环短节经 500 吨拉力、100,000 英尺·磅扭矩载荷。接立柱期间井底压力保持平稳，ECD 波动控制在 5% 以内，适用于窄密度窗口、大位移、控压与空气钻井等高难度钻井项目。
Proven on EP21-4-A1H — China's deepest offshore well, 9,508 m MD (2024); on PY10-5-A1H it lifted ROP ~2.5× over an offset well.
于 EP21-4-A1H 井（中国海上第一深井，井深 9,508 米，2024）验证；在 PY10-5-A1H 井机械钻速较邻井提升约 2.5 倍。
