简介：壳牌和海洋工程国际公司最近在海洋修井攻克了一项新纪录．通过成功更换墨西哥湾一个失效的井下控制安全阀，公司刷新了一项行业记录。作业的成功，标志着公司润滑系统（ＳＩＬＳ）的触水电缆技术在８１５米水深下成功应用。
Shell and Oceaneering International recently achieved a new industry record in subsea well intervention by successfully replacing a failed Subsurface-Controlled Subsurface Safety Valve in the Gulf of Mexico (GOM). The accomplishment, an openwater wireline technique at a water depth of 2,673 ft (815 m), was achieved using Oceaneering's Subsea Intervention Lubricator System (SILS).

The SILS technology is designed to perform cost-effective and safe wireline-based subsea well interventions without the need for a drilling rig, multiservice vessels, or workover riser. The system can perform a variety of operations, including blowout preventer installations, running lubricator sections, making up grease head tool strings, and well plugging and abandonments. It does this at lower day rates and a minimum requirement of third party equipment or resources.

The GOM valve replacement was carried out from the Olympic Intervention IV, a DP-2 vessel equipped with two work class ROVs. The achievement marks a new industry record for producing wells, Shell states, as openwater wireline interventions had been previously deployed in shallower waters, primarily in the North Sea.

"The use of openwater wireline to such a depth is a record that we are proud of, and it is just the latest in a long list of technology firsts for Shell," said Peter Sharpe, Shell's executive vice president   Wells. He called this achievement a game changer, adding that "over the last 10 years, this technology reduced both the costs and frequency of interventions in shallow water, and I am confident we will see the same in deepwater."

Shell aims to reduce costs for these types of maintenance activities and improve ultimate recovery from deepwater reservoirs by expanding on the possibilities of openwater operations. The next focus area will be deepwater-coiled tubing deployment without the need for a drilling rig or large multi-service vessel and workover riser, the company says.

Oceaneering developed SILS over a five year period with input from Shell and other producers. "We are pleased to have been a part of setting this water depth record for openwater wireline," said M. Kevin McEvoy, Oceaneering's executive vice president. "Having demonstrated this technology in deepwater, we believe it can now take its rightful place in the suite of intervention techniques being used to add value through the life of subsea wells."
