Abstract

Abstract: China’s coiled tubing technological development has experienced three stages – introduction of technology, independent development and promotion of application. Jianghan Machinery Research Institute of CNPC Drilling Research Institute has always committed itself to the study in this area during this period of time. As the organizer unit of projects, Jianghan Machinery Research Institute has been in charge of a series of research, experiment and promotion projects for the State and CNPC since 2006, independently developing a number of coiled tubing service technologies and equipment. First of all, the key technology of coiled tubing unit has been developed to entirely replace the imported equipment so that the domestic families of coiled tubing equipment can be used in the mountainous areas and complicated conditions. Secondly, a total of 24 coiled tubing service tools in four families and 35 processes were independently developed to facilitate integrity of tools and workover process, effectively improving the CT service efficiency. Thirdly, the process technology was developed for coiled tubing fracturing and well completion, thus increasing oil production cost-effectively by means of coiled tubing service. Fourthly, the research institute, as an organizer of projects, was involved in formulation of a series of relative technological standards, specification of products and service. The coiled tubing technological industrial chain was preliminarily established in the efforts to provide after-sales service, personnel training and on-the-site demonstration of technology, thus leading to a wider application of coiled tubing technology. Independent technological development substantially raised China’s coiled tubing service technological level and widened its application areas, promoting continual conversion of downhole service technological pattern.

摘要： 我国连续管技术发展经历了技术引进、自主研发和应用推广3 个阶段，期间中国石油钻井院江汉机械研究所始终跟进研究，并自2006 年起作为项目牵头单位，先后承担了国家和集团公司的一系列攻关、试验与推广项目，形成了多项连续管作业技术与装备自主技术和成果：一是攻克了连续管作业机关键技术，形成了适应山地和复杂条件的国产连续管系列成套装备，全面替代进口；二是自主研发4 个系列24 类连续管作业工具和7 大类35 种工艺，完善了工具与修井工艺配套，实现了连续管作业的提速增效；三是形成了连续管压裂与完井成套工艺技术，实现连续管作业低成本增产；四是牵头或参与制定了一系列相关技术标准，规范产品和服务，通过开展售后保障服务、人员培训和现场技术示范等体系建设，初步建立了连续管技术产业链，促进了连续管技术推广应用。技术自主化有力推动了我国连续管作业技术水平的提升和应用规模的增长，促进了井下作业主体技术方式的持续转变。
