摘要 焦作煤田蕴藏着丰富的煤层气资源,因受煤层气的生成、运移、储藏、盖层等条件的制约,各井田、区块富集成藏也存在较大差异。深入研究了该地区影响煤田煤层气富集和分布的因素,即煤层埋深特别是基岩埋深、断裂构造、水文地质条件、煤层顶底板岩性的组合关系以及煤化程度,并提出了焦作煤田煤层气资源富集规律,以及有利于煤层气保存的地质条件,为焦作煤田煤层气的勘查与开发提供了理论依据。 Jiaozuo coalfield was rich in coalbed methane resources. Due to restriction conditions such as formation,migration,storage and cap rock of coalbed methane,each mining field and block also had big differences in enrichment and mineralization. Based on survey and assessment of coalbed methane resource potential in Jiaozuo coalfield,the influencing factors of coalbed methane enrichment and distribution in this region were deeply studied,especially the bedrock buried depth,fault structure,hydrogeological conditions,combination relations of coal seam roof and floor lithologic as well as degree of coalification. Furthermore based on the comprehensive analysis of above aspects,the enrichment regularity of the coalbed methane resources in Jiaozuo coalfield and geological conditions in favor of preservation of coalbed methane were put forward.
