连续管钻井系统海洋应用现状

Application Status of Coiled Tubing Drilling(CTD) in Offshore

在叙述连续管钻井发展历程的基础上,重点分析了连续管钻井系统在海洋老井开发中的应用及获得的经济性。介绍连续管钻井系统在双层套管开窗、地层水平钻进典型应用实例。分析指出了连续管钻井装备在海洋平台布置、工具系统控制在海洋连续管钻井中发挥的重要作用,为国内海洋老井增产提供技术参考,具有指导意义。

Based on the development history of coiled tubing(CT)drilling,the application of the CT drilling system in the offshore old wells was introduced as well as its economical efficiency.Typical application examples of CT drilling system in drilling double casing and horizontal drilling were also introduced.It’s pointed out that the CT drilling equipment can play an important role in the layout of the offshore platform and the control of the tool system in the offshore CT drilling.
