One tool.
Both casings.
Any depth. 一趟管柱。
双层套管。
任意水深。

Before FEODE, foreign monopoly. Our outside-suspension abandonment tool simultaneously cuts 20"×36" or 20"×30" dual-string casing, injects cement plug, and recovers the wellhead — all in one trip. A capability that had never existed in China until 2009. 2009年以前，该技术被国外公司垄断。远东石油外悬挂弃井工具可一趟管柱同时完成双层套管切割（20"×36"或20"×30"）、注水泥塞、回收井口全部三项作业，为中国首创。

TOOL SPECIFICATIONS 工具技术参数

Outside-Suspension Abandonment Tool 深水外悬挂弃井工具

Water Depth适用水深 > 500 m (verified to 2,083 m)
Casing Cut切割套管 20" × 36"  or  20" × 30" (simultaneous, one trip)
Main Load主承载负荷 250 T
Cutting Method切割方式 Pressure-differential hydraulic cutter (tension or compression)
Screw Motor螺杆马达 C7LZ244×7.0
Flow Rate额定排量 42 – 70 l/s
Motor Torque螺杆扭矩 22,500 – 36,000 N·m
Blade Force刀片力 800 – 1,400 kg
Time Saving时间节省 15 – 20 hours per well
vs. WDF (foreign)对比WDF（进口） 250 T vs. 181 T main load — 38% superior

Three functions in one trip: underwater wellhead cutting → cement plug injection → wellhead recovery. No foreign equivalent can match this combination at China's current record depth. 三项功能一趟完成：水下井口切割 → 注水泥塞 → 井口回收。无任何进口工具可在中国当前作业水深下实现同等组合。

Market Share · 2022/2023市场占有率 · 2022/2023
In 2022, CNOOC completed 224 exploration well abandonments globally. FEODE delivered 119 of them — more than all other providers combined. 2022年，中海油全球共完成224口勘探弃井，其中远东石油完成119口，超过所有其他服务商的总和。
$500K
Cost Saving Per Well每口井节省费用
Single-trip execution eliminates additional rig time and foreign tool mobilization costs. Operators save an estimated $400,000 – $500,000 per abandonment operation versus imported alternatives. 一趟管柱作业消除额外钻机时间及进口工具动员费用。与进口工具相比，每口弃井作业估计可节省约40万至50万美元。
250T
Main Load Capacity主承载负荷
38% higher main load than the leading foreign competitor (WDF: 181T). Designed for the extreme mechanical demands of ultra-deepwater operations exceeding 2,000m. 主承载负荷比主要竞争进口产品（WDF：181T）高38%，专为超过2,000米超深水作业的极端机械要求而设计。
