Abstract: The oil and gas fields in the Sichuan-Chongqing region take the lead in use of coiled tubing equipment in China. However, development in this area used to be sluggish for long time owing to the cost for import of coiled tubing equipment and the related services. With China’s first set of coiled tubing unit and coiled tubing developed successfully, the domestic equipment found wide applications in the oil and gas fields in the Sichuan-Chongqing region, thus breaking foreign technological monopoly, reducing the purchase cost, solving the production bottlenecks, improving service ability and achieving remarkable economic performance. This article reviews the process for application of domestic coiled tubing in the Sichuan-Chongqing oil and gas fields and summarizes and analyzes a series of adopted effective measures. They include combination of production with research, cooperation between research institutes and enterprises, reciprocation of each other’s advantages, putting safety first and sharing risks, optimization step by step, market-oriented, guided by technological research, characteristic tailored service and standardized development. The article also analyzes the issues and challenges for the business development and comes up with the related suggestions on further application of domestic coiled tubing in the oil and gas fields in the Sichuan-Chongqing area.

摘要： 川渝油气田在国内率先使用连续管设备，但受限于进口连续管设备成本和服务配套等因素，长期以来发 展缓慢。随着国内首套连续管作业机和连续管的成功研制，国产设备在川渝油气田实现跨越式发展，推广应用中打破 了技术垄断，降低了采购成本，解决了生产难题，提升了服务能力，降本增效显著。文章回顾了川渝油气田国产连续 管推广应用过程，对采取的一系列有效措施进行了总结分析。这些措施包括：加强产研结合，院企合作，优势互补； 安全为先，风险共担，逐步优化；市场导向，科研引领，技术助推；特色定制，集中配套，规范发展。并对发展中所 面临的问题与挑战进行了分析、提出了建议，以期为国产连续管设备在川渝油气田进一步推广应用提供思路。
