摘要
煤层气作为一种清洁能源,与煤矿资源密不可分,煤层气是煤层本身自生自储式非常规天然气。中国南方共发育9套煤系地层,煤层气勘探开发主要层系为上二叠统龙潭组和上三叠统安源组。通过对南方25个形成煤层气条件较好区块进行远景评价,其中Ⅰ类有7块,Ⅰ至Ⅱ类有1块,Ⅱ类有6块,Ⅱ至Ⅲ类有3块,Ⅲ类有8块。它们形成了淮南、徐淮、六盘水、织纳、黔北、富源恩洪、贵阳等7个大型聚煤层气区块。
coal-bed gas as a clean energy resource is closely related to coal resources and regarded as an unconventional natural gas with both source and reservoir. In South China, nine sets of coal measure strata have been found, but the exploration and development of them mainly lie in the Longtan fnrmatinn nf Upper Permian and the Anyuan formation of Upper Triassic. This paper presents the prospective evaluation of 25 hlocks with preferable coal-bed gas conditions, of which Class-1 consists of seven blocks, Class-2 of six blocks, Class-2 to-3 of three blocks and Class-3 of eight blocks. The areas of Huainan, Xuhuai, Liupanshui, Zhina, Qianbei, Fuyuanenhong and Guiyang are the seven large-scale and advantageous blocks with enrichcd coal-bed gas accumulations.
