摘要/Abstract

摘要： 为系统梳理中国连续管技术的发展现状、研判国内外差距、明确未来攻关方向，从装备、管材、工具工艺、软件和数字化全产业链视角，综述了连续管技术的研发与应用进展。中国连续管年作业量已突破10.000井次，形成覆盖修井、压裂、完井、测井、钻井五大领域的53种工艺体系，CT150钢级超高强度连续管、作业能力为Φ60.3.mm-8.000.m（直径为60.3.mm，长度为8.000.m）的超大容量装备、电驱自动化作业机等产品性能达到国际先进水平。但对比国际领先水平，仍存在差距，主要表现为万米超深井/3.000.m以上超长水平段作业能力不足，200.℃/105.MPa极端工况工具失效率高，连续管钻井技术成熟度低，有缆连续管智能作业占比不足国外的20%。针对上述问题，凝练了管柱非线性力学、极端工况材料失效、井下智能感知控制等关键技术难题，提出了持续突破极限作业能力、升级完善连续管钻井技术、加快数智化转型、推进新能源业务拓展及深化国际交流合作5项发展建议，以期为中国连续管技术从“并跑”向“领跑”跨越提供参考。

Abstract: To systematically review the current development status of coiled tubing (CT) technology in China, identify the technological gaps between domestic and international levels, and define future research priorities, this paper provides a comprehensive overview of the research and application progress of CT technology across the entire industrial chain, including equipment, strings, downhole tools and operational processes, as well as digital software systems. China’s CT intervention capacity has exceeded 10.000 well services annually, with 53 process technologies established across five major application fields, namely workover, fracturing, completion, logging, and drilling. The core technologies, such as CT150 ultra-high-strength coiled tubing, Φ60.3.mm-8.000.m ultra-large-capacity equipment, and electrically driven automated coiled tubing units, have attained globally recognized performance benchmarks. However, China’s CT technology still lags behind international benchmarks in several key aspects, including insufficient operational capabilities for ultra-deep wells exceeding 10.000.m and ultra-long horizontal sections longer than 3.000.m, high failure rates of downhole tools under extreme conditions of 200.℃ and 105.MPa, relatively low maturity of coiled tubing drilling technology, and adoption rate of intelligent wired coiled tubing less than 20% of the global benchmark. In response to these challenges, this study identifies the critical technical bottlenecks, encompassing nonlinear mechanics of CT strings, material failure mechanisms under extreme operating conditions, and intelligent downhole sensing and control technologies. Five strategic recommendations are proposed:continuously enhancing extreme operation capabilities, improving and advancing CT drilling technologies, accelerating digital and intelligent transformation, expanding applications in new energy sectors, and strengthening international exchanges and cooperation. These recommendations provide valuable guidance for propelling China’s CT technology from parallel development to global leadership.
