我国煤层气资源勘探开发前景

Exploration and development prospects of coal bed methane(CBM) resources in China

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。

Based on studying exploration and development situation, resource potential, and reserve growth of CBM, some advice were put forward to promoting the development of the CBM industry in China. Resource in place of CBM in 2,000 meters depth to the shallow is 36.81 trillion m^3 and recoverable resource of CBM in 1500 meters depth to the shallow is 10.87 trillion m^3. The resources are mainly distributed in 9 large-scale basins that its resources in place are more than one trillion m^3 , including Ordos Basin, Qinshui Basin, etc. The proved reserves in place of China＇s CBM were forecasted to be rapid development stage after 2010. Proved reserves in-place of gas （CBM） will reach 4000×10^8m^3 in 2010, 12000 ×10^8m^3 in 2020. The CBM production will reach 100×10^8m^3 in 2010, 300×10^8m^3 in 2020.
