CORE TOOL核心工具

Outside-Suspension Single-Trip Cutting & Retrieval System 深水外悬挂一趟式套管切割回收工具

A fully domestically developed deepwater subsea wellhead retrieval system. The single-trip rotary spear, hydraulic cutter, and screw-motor outside-suspension power assembly perform synchronised cutting and retrieval in one run — saving 15-20 hours and US$400-500k per well compared with conventional methods. 完全自主研发的深水水下井口切割回收系统。一趟式旋转捞矛、水力割刀与外悬挂螺杆动力总成在一趟作业中完成同步切割与回收 — 较传统方法每井节省 15-20 小时、40-50 万美元成本。

TECHNICAL ADVANTAGES技术优势

Why operators choose FEODE for deepwater P&A 国际作业商选择远东弃井的原因

Single-Trip Synchronised Operation一趟式同步作业

Cutting and retrieval performed in a single run-in-hole — eliminating one full round-trip of pipe handling and reducing operational risk on critical-path rig hours.切割与回收在同一趟作业中同步完成 — 省去一趟起下钻时间，减少关键路径作业风险。

Cuts Under Tension带张力切割

Slip mechanism remains stationary while the cutting head operates under tension — providing a cleaner cut and the ability to back-out and release at any moment if needed.卡瓦机构保持静止，切割头在张力作用下作业 — 切割面更平整，且可随时倒开脱手。

Fully Domesticated Technology全国产化技术

The first fully domestic outside-suspension screw-motor cutting & retrieval system in China, breaking the foreign monopoly on deepwater subsea wellhead retrieval since 2009.国内首套全国产化外悬挂螺杆动力水下井口切割回收系统，自2009年起打破国外垄断。

National Patent & Major Programme Output国家专利与重大专项成果

Holder of multiple national patents. Originally developed under China's 12th Five-Year Plan National Major Science & Technology Programme.获多项国家专利。国家科技重大专项十二五立项成果。

Time & Cost Saving显著的时间与成本节约

15-20 hours saved per well versus conventional methods. US$400-500k cost reduction per operation — directly improving project economics and reducing weather-window exposure.较传统作业每井节省 15-20 小时，降低成本 40-50 万美元 — 直接改善项目经济性，减少作业窗口暴露风险。

National Award Recognition国家奖项认可

National Science & Technology Progress Award — Second Prize (2007), and Shenzhen Science & Technology Progress Award — Second Prize (2020, "Deepwater Subsea Wellhead Cutting & Retrieval Tool System").国家科技进步二等奖（2007）；深圳市科技进步二等奖（2020，"深水水下井口切割回收工具系统研制及应用"）。
