| 摘 要： | 通过对吉林省煤层气的地质特征分析可以看出,煤层气藏的形成是多种地质因素共同作用的结果,它在时空上的分布和区域构造、沉积环境、含煤岩系的岩性组合密切相关。煤层气聚气区多分布在成煤条件相对好的地区,而含煤盆地的沉积类型则控制着聚气带在盆地内的展布。冲积平原类型的含煤盆地,聚气带多发育在远离河道的河流沉积旋回的上部,而山间湖泊类型的含煤盆地,聚气带则发育在山麓相前缘的湖相泥岩上下。长春煤田、辽源煤田和通化煤田是开发利用煤层气资源最有利的首选地区。

| Abstract: | Through the analysis of CBM geological characteristics in Jilin Province can see the form of CBM reservoir is a collective result of multiple geological factors. Its space-time distribution has close relation with tectonics, depositional environment, lithological combination of coal-bearing strata. CBM accumulation area is mainly distributed in good coal-forming condition areas, depositional type of the coal-bearing basin controls distribution of methane-accumulating zone in the basin. In alluvial plain coal-bearing basin, methane-accumulating zone is mainly developed in upper part of fluvial depositional cycle apart from river channel, while in intermontane lacustrine basin, developed in piedmont front above and under lacustrine mudstone. Changchun, Liaoyuan and Tonghua coalfields are preferred areas of CBM exploitation and utilization. |
