根据《新一轮全国油气资源评价》成果,我国煤层气资源丰富,42个主要含气盆地埋深2000m以浅煤层气地质资源量36.8×1012m3,埋深1500m以浅煤层气可采资源量10.9×1012m3,地质资源量大于1×1012m3的含气盆地(群)有鄂尔多斯、沁水等9个盆地(群)。文章通过对中国煤层气资源勘探开发现状和资源潜力的深入剖析,预测了中国煤层气储量和产量未来的增长趋势,我国煤层气产业将在2010年以后进入快速发展阶段,预计2010年累计探明地质储量4000×108m3,瓦斯(煤层气)抽采量达到100×108m3。2020年累计探明地质储量为12000×108m3,产量超过300×108m3。并指出了沁水盆地、鄂尔多斯盆地东缘等是煤层气勘探开发的最有利区带。最后,提出了促进中国煤层气产业发展的建议,即重视和加强煤层气资源的勘探开发、加大基础性地质工作投入、加强科技攻关、优先开发利用煤层气资源、加强煤层气资源管理。
According to the results of “a new round of evaluation of oil and gas resources in China”, China has abundant coalbed methane resources. The main gas-bearing basins of the 42 major gas-bearing basins are buried at depths of 2000 m with 36.8 × 1012 m 3 of shallow CBM resources and shallow coalbed methane recoverable resources of 10.9 × 10 12 m 3 , Gas basins (groups) with geological resources larger than 1 × 1012m3 include 9 basins (groups) such as Erdos and Qinshui. Based on the deep analysis of CBM resources exploration and development status and resource potential in China, the paper predicts the future growth trend of CBM reserves and output in China. CBM industry in China will enter a stage of rapid development after 2010, and is expected to accumulate in 2010 Geological reserves of 4000 × 108m3, gas (coal-bed methane) extraction volume reached 100 × 108m3.2020 annual summary of proven reserves of 12000 × 108m3, output of more than 300 × 108m3. It is pointed out that the Qinshui Basin and the eastern edge of Ordos Basin are the most favorable zones for CBM exploration and development. At last, some suggestions to promote the development of CBM industry in China are put forward, which include paying more attention to and strengthening the exploration and development of CBM resources, increasing investment in basic geological work, strengthening scientific and technological research, giving priority to exploitation and utilization of CBM resources, and strengthening CBM resource management.
