摘要
据最近一轮煤层气资源评价结果,我国埋深2000m以浅的煤层气资源总量为36.81×1012m3,与陆上常规天然气资源量相当,位列世界前三甲。中国地面开发煤层气经过十余年的发展,在政府的高度重视和支持下,在煤层气基础理论研究、煤层气勘探开发技术、煤层气商业化生产等方面都取得了突破性进展,为煤层气产业规模化生产奠定了基础。截至2006年底,全国共施工地面煤层气井1573口。我国煤层气井主要分布在晋、陕、蒙地区,其钻井数量占全国钻井总数的80%以上。我国已探明煤层气储量1130.29×108m3,约占煤层气资源总量的0.3%,其中地面开采探明煤层气地质储量861.65×108m3,矿井抽放探明煤层气地质储量268.64×108m3。中国煤层气产业不仅煤层气自营勘探开发实现了跨越式发展,而且对外合作开发煤层气也取得了累累硕果,并逐步形成了一套适合中国煤层气地质特点的煤层气地质评价和常规勘探开发工艺技术。
Based on the latest statistics,CBM resource reserves in China,the top third country in the world,have been up to 36.81 TCM in total under the burial depth less than 2000 m,equivalent to the conventional natural gas resource on the land.After ten more years in exploiting CBM under the support by the government,CBM industry in China has achieved in many progresses including the basic theory research,E & P technology,commercial production,etc.,which provide ground for CBM production in large scale.By the end of 2006,1573 CBM gas wells had been drilled and completed.80% of the drilled CBM gas wells are distributed mainly in Shanxi,Shaanxi,and Mongolia Autonomous Region.At present 0.3% of total CBM resource has been tapped to be 113.029 BCM as the explored CBM reserve,86.165 BCM of which can be obtained by ground exploitation,and 26.864 BCM got by mining extraction.CBM industry has not only found its own way in exploration and development in recovery of coal bed methane,but also achieved good results by cooperating with other countries.The most important of all is that the CBM industry owns a set of technology and techniques on CBM geological assessment and conventional exploration and development.
