连续管钻井工具技术现状与发展趋势
Current Status and Development Trend of Coiled Tube Drilling Tool Technology
摘要: 连续管钻井工具技术凭借结构紧凑、控制精准、井下适应性强的核心优势，已在国际高端钻井市场实现规模化应用，显著提升钻井效率并降低事故率；而国内尚未突破核心工具工程化瓶颈，目前连续管技术仅用于常规修井作业，钻井级工具系统仍依赖进口。为攻克上述瓶颈，本文系统梳理连续管钻井(CTD)核心工具——井下定向器的技术进展，从驱动方式革新、结构优化、智能控制三个维度分析现状，总结出当前攻关重点在于高精度位移控制与高温高压适应性，并指出智能化、模块化及超深井应用为未来发展趋势。
Abstract: With the core advantages of compact structure, precise control and strong downhole adaptability, continuous tube drilling tool technology has been applied on a large scale in the international high-end drilling market, significantly improving drilling efficiency and reducing accident rate. However, China has not yet broken through the bottleneck of core tool engineering, and the continuous pipe technology is only used for conventional workover operations, and the drilling-grade tool system still relies on imports. In order to overcome the above bottlenecks, this paper systematically sorts out the technical progress of downhole orienter, the core tool of continuous pipe drilling (CTD), analyzes the current situation from three dimensions: drive mode innovation, structural optimization and intelligent control, summarizes the current research focus on high-precision displacement control and high temperature and high pressure adaptability, and points out that intelligence, modularity and ultra-deep well application are the future development trends.
