Abstract: China National Petroleum Corporation has launched a special campaign for promotion of coiled tubing service technology since 2011 and made remarkable achievements in this area. Coiled tubing unit has played an important role as “universal service unit.” Coiled tubing service technology is used to solve the production bottlenecks in operation of shale gas horizontal wells. “Qinghai Experiences” were developed in using coiled tubing technology for conventional service to substantially raise speed and efficiency. Coiled tubing service equipment and tools as well as dedicated tubular are independently development in different families. The specialized standards and engineering service capability of coiled tubing crews are fully improved at the same time. Against the background of continual low oil prices on the international market and increasingly stern requirements on the environment at home, CNPC has accelerated the process of promoting CT technology and expanded application areas in its special campaign for CT technological promotion. Those efforts are helpful to conversion of downhole service pattern and operational cost-effectiveness.

摘要： 2011 年以来，中国石油天然气集团公司持续开展连续管作业技术专项推广工作，现已取得显著成效。连 续管作业机作为“万能作业机”的功能得到充分体现；利用连续管作业技术解决了页岩气水平井作业等生产难题；形 成了将连续管技术用于常规作业实现大幅提速增效的“青海经验”；连续管作业设备、工具和专用管材等自主产品实 现系列化；连续管作业队伍专业化水平和工程服务能力全面提升。在国际油价持续低迷和国内环保要求更加严苛的背 景下，集团公司利用“专项推广模式”发挥整体优势，加快推广进程、加大推广力度，扩大推广应用范围，有利于促 进井下作业方式的持续转变，充分发挥其降本增效的作用。
