摘要:

深水救援井具有高风险,高技术,高投入和高社会敏感性等特点.在深水作业井失控,常规救援措施难以有效实施时,深水救援井是公认的终极救援手段.目前我国救援井数量较少,深水救援井经验几乎为空白.在调研国内外救援井的基础上,对深水救援井一系列关键技术进行了梳理和分析.对救援井的井位选择,轨迹连通,压井和弃井等几项关键技术,进行了技术分析,可为后续的救援井研究提供一定参考.

关键词: 深水钻井, 救援井, 轨迹, 连通技术, 压井, 弃井

Abstract:

Deepwater relief wells exhibit characteristics of high risk, high technology, high investment and high social sensitivity. When the well is out of control and the routine rescue measures fail, relief well is regarded as the ultimate rescue means. However, in China, the quantity of relief wells is relatively small, and the deepwater relief well experience is almost blank at present. Based on the research of relief wells at home and abroad, a series of key technologies of deepwater relief well are sorted and analyzed. Several key technologies such as location selection, the trajectory of relief well connected, well control and well abandonment are analyzed. The results provide certain reference for subsequent relief well study.

Key words: deepwater drilling, relief well, trajectory, connecting technology, well control, well abandonment
