摘　　要：为了提升连续管导向钻井技术在深层油气层作业中的效率与安全性,对连续管导向钻井控制系统与工作状态进行了研究。总结了连续管导向钻井工具的地面闭环控制系统和井下闭环控制系统的研究现状,并分析了双闭环通讯系统的工作特点。基于此,深入探讨了连续管导向钻井系统的三种工作状态及其转换机制,并研究了这些工作状态与电机同步策略的结合应用。同时提出了针对现有系统优化与改进的建议,以提高系统的响应速度和作业精度。开展了钻具轨迹自动修正系统,分析了针对深层油气层和复杂作业环境下控制能力精细化的挑战,以期为该领域的技术进步和应用提供指导。In order to improve the efficiency and safety of coiled tubing drilling technology in deep oil and gas reservoir operations, a study was conducted on the control system and working status of coiled tubing drilling, summarized the research status of ground closed-loop control system and downhole closed-loop control system for continuous tube guided drilling tools, and analyzed the working characteristics of the dual closed-loop communication system. Based on this, the three working states and their transition mechanisms of the coiled tubing drilling system were deeply explored, and the combined application of these working states and motor synchronization strategy was studied. At the same time, suggestions were put forward for optimizing and improving the existing system to enhance its response speed and operational accuracy. We have developed an automatic correction system for drilling tool trajectories and analyzed the challenges of refining control capabilities for deep oil and gas reservoirs and complex operating environments, in order to provide guidance for technological progress and applications in this field.
