摘要
根据现代钻井工程技术的发展规律,综述了井下闭环钻井系统的可行方案、主要特征及技术发展背景,给出了井下闭环钻井系统的分类和适用范围。同时从钻达能力、经济效益两个角度论述了发展井下闭环系统的必要性。分析认为,以地质导向为特点的旋转式井下闭环钻井系统将成为未来井下闭环钻井系统的发展模式。
Considering modern drilling technology,the feasible types,characteristics and developing background of underground closed loop drilling system have beed analyzed synthetically in this paper.The necessity of developing underground closed-loop drilling systems was demonstrated from the points of extended reach ability and economic benefit.The suitable range of underground closed-loop drilling system with geo-steering technology will be the future model.
