作为智能化钻探的重要组成部分，钻具系统的智能化对煤矿井下钻探的智能化发展起着至关重要的作用。为深入探究智能化钻具的发展方向，结合石油天然气行业发展经验，从定向钻具、随钻测量系统以及智能化钻杆、钻头等方面系统梳理了煤矿井下智能化钻探配套钻具的研究成果与技术特点，总结了存在的不足。指出目前煤矿井下智能化钻探定向钻具多以螺杆马达为主，主要研究集中于螺杆马达的线形设计、定子橡胶抗疲劳研究与不同工艺个性化定制，旋转导向钻具的开发与石油天然气行业存在较大差距，仅处于起步阶段；随钻测量系统可监测参数较少，监测的数据以轨迹参数为主，逐步加入了伽马地层识别，数据传输以有线与泥浆脉冲方式为主，存在数据容量小、传输效率低的问题，无线电磁波方式传输距离较短，仅能满足500 m以内钻孔；智能化钻杆研究主要为通缆钻杆的优化与改进，智能化钻头的研究尚未开展。为实现煤矿井下智能化钻探，提出开展以旋转导向为主，多种定向钻具综合运用的钻具定向系统研究；随钻监测系统应集成瓦斯监测、地下水探测及地应力感知煤矿钻进特种需求的功能，并配合多种传输方式并存的随钻测量系统研究以适配不同钻进工艺，同时提升传输速率，实现信息高速双向传输；开展载荷自监测的智能化钻杆与破岩参数自监测的智能化钻头研究。通过钻具系统的优化组合，形成集高效破岩钻进、钻孔轨迹动态调整、钻具自身状态监测以及瓦斯与地下水、地应力实时监测功能于一体，具备双向通信、自适应调控的智能化钻具系统。上述研究成果将丰富对煤矿井下智能化钻探配套钻具系统的全面认识，为智能化钻探配套钻具系统的后续开发提供依据与指导。

As an important part of intelligent drilling, the intelligence of drilling tool system plays a crucial role in the intelligent development of coal mine underground drilling. In order to deeply explore the development direction of intelligent drilling tools, the research results and technical characteristics of intelligent drilling tools in coal mines were systematically sorted out from the aspects of directional drilling tools, measurement while drilling (MWD) system, intelligent drilling pipes and drill bits with reference to the experience in development of oil and gas industry, and the existing shortcomings were also summarized. It is pointed out that screw motor is mainly used at present in most of the intelligent directional drilling tools in coal mines, the research focuses on the geometric design of screw motor, the fatigue resistance of stator elastomer and customization of different technologies, and the development of rotary steerable drilling tools is in start-up phase, greatly deferring from the oil and gas industry. The MWD system can monitor few parameters, and the monitored data is mainly composed of the trajectory parameters. Therefore, Gamma formation identification was introduced gradually. The data was mainly transmitted by wire and mud pulse, with the problems of small data capacity and low transmission efficiency. However, the data transmission by wireless electromagnetic wave is only applicable in case of short distance, only satisfying the requirements of boreholes within 500 m. The research of intelligent drilling pipe was to optimize and improve the cable drill pipe, and the research of intelligent drill bit has not yet been carried out. In order to realize the intelligent drilling of coal mine, it was proposed to carry out the research on the orientation system of drilling tools based on the rotary steerable system and the comprehensive application of a variety of directional drilling tools. The MWD system should integrate the functions, such as gas monitoring, groundwater detection, ground stress sensing, and special requirements of coal mine drilling. Meanwhile, research was conducted on the MWD system with coexistence of multiple transmission methods to adapt to different drilling technologies, improve the transmission speed and realize the high-speed bidirectional transmission of information. Further, the intelligent drill pipe with load self-monitoring and the intelligent drill bit with self-monitoring of rock breaking parameters were also studied. Thereby, an intelligent drilling tool system with two-way communication and adaptive regulation that integrates the efficient rock breaking drilling, dynamic adjustment of drilling trajectory, drilling tool self-condition monitoring, and real-time monitoring of gas, groundwater and in-situ stress was developed through the optimal combination of drilling tool systems. The above research results will enrich the comprehensive understanding of the intelligent drilling tool system in coal mine, and provide the basis and guidance for the subsequent development of the intelligent drilling tool system.
