中国煤层气资源潜力及增产措施

摘要

The coalbed methane resources potential is huge in China, and Northwest and North China are main favorable zones. By summarizing domestic and foreign experience of CBM, we introduced three major ways to improve recovery rate, which include cluster & horizontal well, hydraulic fracturing and enhanced coalbed methane. Finally, future trend of exploration and development for CBM were prospected.%中国煤层气资源潜力巨大，以华北和西北聚煤大区为主要煤层气富集区。通过总结国内外煤层气开发经验，指出了目前用于提高煤层气的主要增产技术，即丛式井与定向羽状水平井、水力压裂改造技术和注气驱替技术，这也是目前国内外煤层气开发单位集中力量重点研究的增产技术；最后对我国煤层气的勘探开发前景进行了展望。
