摘要
在系统总结前人关于构造活动对煤层气成藏影响方面研究成果的基础上,从3个不同的层次剖析了构造活动对煤层气成藏的控制作用:就含煤盆地层次而言,区域构造背景及其演化是控制煤层气聚集区带形成和分布的根本要素;就含煤盆地内部次级构造层次而言,不同的构造样式及构造岩性圈闭是控制煤层气赋存、富集的主导因素;而从储层层次来看,构造通过对储层孔隙—裂隙系统的影响控制了煤层渗透率及其非均质特性。
Based on predecessors studies of tectonic activity influence on CBM pool, from three different hierarchies dissected control action of tectonic activity on CBM pool： ① With regard to coal-bearing basin, tectonic background and its evolution are basic factors to control formation and distribution of CBM accumulating zones; ② On secondary structures in coal basin, different form of structure and structural lithologic trap are dominant factors to control CBM hosting and enrichment; ③ From reservoir, structure controls coal seam permeability and anisotropy via its influence on reservoir void and fracture system.
