中国煤层气勘探开发工程技术进展与发展方向

受美国、加拿大、澳大利亚等国家煤层气快速发展的影响，加之国家出台了一系列优惠扶持政策，我国的煤层气业务得到了一定的发展，但工程技术难题在很大程度上影响和制约着我国煤层气勘探开发的快速推进。为此，总结了近年来中石油煤层气有限责任公司、中联煤层气有限责任公司等相关企业在煤层气工程技术方面的攻关成果与技术进展，包括煤层气地质综合评价技术、煤层气钻完井技术、煤层气压裂改造技术、煤层气排水采气技术、煤层气地面工程技术等；进而明确提出了涉及上述5方面技术的下一步发展方向和研究目标。

Advances in the CBM exploration and development techniques and their developing trend in China

Influenced by those big CBM gas producing countries like the U.S., Canada, and Australia, etc., domestic CBM gas is being developed well by the aid of the government's preferential policies, but significantly restricted by the bottleneck problems in the engineering technology. In view of this, this paper summarizes recent years' achievements and technical progress in the following 5 aspects made by those domestic companies such as the PetroChina CBM Co., Ltd. and the China United CBM Co., Ltd., etc.: integrated geological evaluation, drilling and completion, fracturing treatment, water drainage and gas recovery, and ground surface engineering. Additionally, the further developing trend and research goals are presented for the above five aspects.
