【摘要】 中国石油连续管作业经过“十三五”持续攻关与示范推广，技术取得很大进步，作业量快速增长。在连续管径向钻井与侧钻、超深井及深部页岩/致密油气连续管作业、连续管定向喷砂射孔压裂、连续管悬挂完井与采油采气4个领域，连续管工艺技术与关键工具研究、装备研制与软件开发等方面均取得重要进展。依托连续管快速修井、连续管速度管柱与完井管柱、连续管储层改造与连续管测井测试4项主体工艺的示范推广，连续管作业量以每年递增22%的速度快速增长。随着油气开发向更深层、更长水平段发展，“十四五”期间连续管技术将面临一系列新的挑战，需进一步提升连续管装备水平与作业能力，加强全系列连续管作业技术的专项推广，推进技术共享服务平台和数字化智能化软件平台建设，为“稳油增气，提质增效”双重战略实施提供强有力的技术支持。更多还原

【Abstract】 China National Petroleum Corporation(CNPC) has made significant progress in coiled tubing service technology and scored a rapid business growth in service volume following the continuous efforts for research and extension of coiled tubing service in the 13th Five-year Plan period. In the four areas of radial drilling sidetracking, ultra-deep well and deep-layer shale/tight oil and gas coiled tubing service, coiled tubing directional sand blasting perforation fracturing, and coiled tubing suspension completion and oil/gas production, CNPC has made important achievements in research of coiled tubing process technology and key tools, manufacture of equipment and software development. The coiled tubing service business has rapidly risen 22 percent year by year in the efforts to promote four main processes – coiled tubing rapid workover, coiled tubing velocity string and completion string, coiled tubing reservoir stimulation and coiled tubing logging and testing. With oil and gas development extending into deeper layers and longer horizontal section, coiled tubing technology will face a series of new challenges during the 14th Five-year Plan period. It is necessary to improve coiled tubing equipment and service competence, enhance promotion of the whole series of coiled tubing service technology,accelerate construction of technology sharing service platform and digitalized and intelligent software platform, and provide effective technological support for the dual strategy of “keeping oil production stable while increasing gas production and improving quality for higher efficiency”.更多还原
