The Status of Current Research on Downhole Robots and their Multiple Applications

  • 摘要: 针对水平井测井、压裂等作业中井下管柱下入困难的问题,国内外开展了井下机器人的研究与应用。根据井下机器人的结构特点及功能,将其分为井下牵引机器人和井下钻井机器人2大类,并详细介绍了其支撑机构、驱动系统、控制系统和能源供给系统等4大关键技术的功能、设计方案及性能参数。同时,总结归纳了国内外井下机器人的最新研究进展,指出小型化和安全性是井下机器人研究的目标、伸缩式智能控制钻井机器人是井下钻井机器人的主要发展方向,并基于井下机器人技术提出了连续油管多分支微小井眼水平井完井技术、连续油管智能闭环钻井技术和无线单桥塞水平井分段压裂技术。研究结果为我国井下机器人的研究、设计和应用提供了参考和借鉴。

     

    Abstract: The research and application of downhole robots has been carried out at home and abroad for addressing the difficult RIH of logging and fracturing pipe strings in horizontal wells. Two categories of downhole traction robots and drilling robots have been determined based on the structural characteristics and functions of downhole robots. The functions, design schemes and performance parameters of four key technologies, including support structure, drive system, control system and energy supply system were introduced in detail and the latest research progress of downhole robots at home and abroad were summarized. Studies indicated that the researches of downhole robots could be focused on the miniaturization and safety, and the telescopic intelligent control drilling robots should be developed preferentially. Based on the development of downhole robots, forward-looking technologies such as multi-lateral micro-hole horizontal well completion, coiled tubing intelligent closed-loop drilling, wireless single bridge plug staged fracturing in horizontal wells, etc., have been advanced. This paper provides a guide for the research, design and application of downhole robots in China.
