Abstract: Intelligent Coiled Tubing Drilling (ICTD) is the product of a deep integration between traditional coiled tubing drilling technology and information technology and intelligentization. It aims to meet the higher demands for drilling precision, efficiency, and safety in the development of deep and complex oil and gas resources. This paper reviews the current status of coiled tubing drilling technology both domestically and internationally, pointing out that while China leads in market scale, there is a technological generation gap in core tools, software, and system integration. It constructs a cutting-edge ICTD system (including intelligent surface/subsurface tools, high-speed transmission, digital twins, and intelligent decision-making) and summarizes the progress in technologies such as re-entry drilling and ultra-extreme well processes. Addressing bottlenecks like reliance on imported tools, weak software ecosystems, and lack of systematic integration, the paper proposes key breakthroughs in high-speed transmission and rotary steering, the construction of autonomous software and digital twin platforms, the promotion of collaborative standardization, and the expansion of applications in unconventional resources and new energy sources. The research concludes that adhering to core technology self-development, domestic software solutions, and systematic standardization is crucial for achieving a leapfrog in high-end technology and supporting national energy security.
