摘要
通过对美国主要煤层气开发盆地的地质特性与中国主要煤层气勘探开发地区(盆地)的地质 条件进行对比研究,中国煤层受成煤期沉积环境和成煤期后构造活动的影响很大,煤层的非均质性表 现非常明显。今后主要侧重于主生气期与主构造活动期的匹配关系研究,以及加大煤层气开发工程技 术的研究和应用。
Based on comparison of geological characteristics of major CBM development basins in USA and major CBM development regions in China we find that the sedimental environment in coal formation period and tectonic activities after coal formation have a great influence on coal seams in China. The coal seams have evident anisotropic (heterogeneous) characteristics. In the future the research will focus on compatibility between gas formation period and main tectonic activity periods. Great efforts will be made on research and application of CBM development engineering technology.
