山西沁水盆地南部（以下简称沁南）煤层气开发利用高技术产业化示范工程是国家发展和改革委员会于2004年12月正式批准实施的第一个国家级煤层气开发示范工程项目。中联煤层气有限责任公司作为项目主管单位和建设单位，积极推进项目建设，2009年10月，示范工程一期150口井气田建设全面竣工投产，达到了1×108 m3/a的产能建设规模。这标志着中国煤层气地面开发正式步入快速发展的大规模商业化轨道，为沁南煤层气的商业开发起到了示范和推动作用，加速了中国煤层气产业化的进程。该示范工程采用现代化的项目管理模式，进行了较好的项目组织管理及工程质量控制，形成了“300 m×300 m井网部署”、“空气钻井技术”、“微珠低密度固井技术”、“清水加砂压裂技术”、“氮气泡沫压裂技术”、“分片集输一级增压地面集输技术”、“稳控精细排采技术”、“无烟煤储层生产特征分析”等8项适合于沁南高阶煤的技术系列，并得到了推广应用。另外还对新材料、新装备进行了试验应用，并制订了煤层气两个行业标准和两个企业标准，对国内煤层气田直井开发具有借鉴和示范作用。

The hightech and commercial demonstration project of coalbed methane (CBM) gas exploitation and utilization in the southern Qinshui Basin is officially approved and implemented by National Development and Reform Commission in September 2004 as the first statelevel CBM gas development demonstration project. Responsible for such a project, China United Coalbed Methane Company Limited had worked on it for 5 years until the first stage of this project was completed in October 2009, when the annual CBM gas production of 1×108 m3 was obtained from a total of 150 wells. This success marks a leap forward in commercial development of CBM gas industry in China, setting a style for the rapid exploitation of CBM gas in the southern Qinshui Basin, thus accelerating the process of domestic CBM gas industrialization. Experiences learned from this demonstration project are concluded herein in this paper. 1) A modern management mode plays an effective role in the project organization and quality monitoring and control. 2) About 8 technical series have been developed worthy of being promoted and adaptable for the highrank coals in the southern Qinshui Basin, including 300 m×300 m well pattern arrangement, air drilling, hollow microspheres low density cementing, water sand fracturing, nitrogen foam fracturing, perwell gas gathered by fractional valve sets to the boosting station, fine stable controlling technologies of water drainage and gas production, characteristic analysis of anthracite coal bed production. 3) Pilot tests and field practices have been conducted on new materials and new equipment and two industry standards and two enterprise standards have been worked out and can be regarded as reference and models for domestic CBM gas development of vertical wells.
