沁水盆地煤层气资源潜力及开发利用前景

尽管沁水盆地已进入煤层气规模开发利用阶段,成为我国两大煤层气产业化基地之一,但其储量产量增速放缓,距离规划目标仍有较大差距。本文梳理总结勘探进展,开展沁水盆地煤层气资源评价。评价结果表明:沁水盆地煤层气地质资源量4.00万亿m3,可采资源量1.53万亿m3,资源潜力巨大。盆地北部太原组15#煤层和南部山西组3#煤层是当前及今后勘探开发的重点,盆地南部夏店-沁南区块是未来储量增长的重要潜力区。面对地质、技术、效益、管理等多方面条件的制约和挑战,要坚定发展信心,抓住发展机遇,实现沁水盆地煤层气产业的进一步发展,为保障国家能源安全作出贡献。

Resources potential and exploration prospect of coalbed methane in Qinshui basin

Although Qinshui basin has entered the stage of large-scale development and utilization of coalbed methane (CBM) and become one of the two industrialization base in China, proved reserves and production in it is far from the planning objectives and the growth is slowing down. In this paper, the exploration progress in the basin was analysed, and assessment of CBM resources was conducted. According to the assessment, original CBM in place is 4.00 trillion cubic meters, of which 1.53 trillion cubic meters is recoverable, and it indicates the huge potential of CBM resources in Qinshui basin. No.15 Coal seam in Taiyuan formation in the north and No.3 coal seam in Shanxi formation in the south is the major target for exploration at present and in the future. Xiadian and Qinnan blocks in the south of the basin are important potential areas for reserve growth in the future. Facing with the constraints and challenges from various aspects, like geology, technology, economic benefits and management, it is high time to enhance the confidence and seize the opportunities to achieving the further development of CBM industrialization in Qinshui basin that contributes to ensure the national energy security.
