摘　　要：分析了国内外煤层气钻机的发展现状,详细介绍了国外主要钻机生产厂商所研制的煤层气钻机的结构特点、应用情况及国内煤层气钻机的研制开发情况。分析认为,国外煤层气钻机发展成熟,结构紧凑、自动化程度高、效率高,其产品已经形成系列化;而国内则主要借用常规油气钻机、煤田钻机和水文钻机等,钻井成本高、效率低,阻碍了煤层气产业的快速发展。同时,对国内外煤层气井井控设备的发展进行了分析,指出了国内煤层气井井口防喷器和旋转控制头在设计、制造和配套应用方面存在的问题和发展方向。然后,对国内煤层气钻井装备研制开发中存在的问题进行了归纳总结,提出了解决这些问题的具体建议,并指出我国应该抓住机遇研制开发高效的煤层气钻井装备,加快我国煤层气产业的发展,以优化我国的能源结构。The development of coalbed methane drilling equipment at home and abroad was analyzed.This paper introduced structural features and application of rigs for coalbed methane by major foreign manufacturers along with domestic research and development.The analysis showed that the development of foreign rigs for coalbed methane is mature with compact structure,high degree of automation and high efficiency,and series products are already formed.While in China conventional rigs,coalfield rigs and water well rigs are often employed in coalbed methane drilling,which restricted the development of coalbed methane due to high cost and low efficiency.The development of well-control equipment in coalbed methane drilling at home and abroad was analyzed.The existing problems and development direction of well-control equipment and rotating control head used in coalbed methane drilling,in terms of design,manufacture and match application,have been pointed out.Finally,the existing problems of domestic coalbed methane drilling equipment were summarized,and specific recommendations to address these issues were made.This paper pointed out that China should seize the opportunity to develop the modern high-efficient drilling equipment for coalbed methane drilling,in order to accelerate the development of domestic coalbed methane and optimize energy sources structure.
