摘要
煤层气赋存规律和控制因素是煤层气勘查中的首要研究问题,煤层气的分布特征及影响因素对于制定煤层气的开发方案具有非常重要的意义。本文论述了4号煤储层地质特征及其含气性基本特征,分析了4号煤含气量与沉积环境、煤层埋深、煤层厚度、煤质、围岩性质、构造、水文地质条件的关系。结果表明,煤层厚度与含气量呈明显正相关性,煤层埋深、煤质与含气量呈负相关性,当顶底板岩性为泥岩时含气量高,研究区沉积环境、井田构造与水文地质条件较有利于煤层气赋存。最终,明确影响研究区煤层气赋存的主要因素为煤层埋深、煤层厚度和顶底板岩性。
Occurrence regularity of coalbed methane and controlling factors is a primary research issue in CBM exploration,coalbed methane distribution characteristics and influence factors have very important significance for the development plan of coalbed methane.Based on the previous studies,this paper collected,finished and analyzed the geological data of the past,and discussed the geological features of coal reservoir and its gas bearing basic features of the 4~# coal reservoir,analyzed the relationship between containing gas of 4~# coal and sedimentary environment,coal seam buried depth,thickness of coal seam,coal rock properties,surrounding rock properties,geological structure,hydrogeological conditions.The results showed that the thickness of coal seam and gas content had a significant positive correlation,coal buried deep,coal properties and gas content had a negative correlation,when the lithology of roof and floor was mudstone which containing high gas volume,the sedimentary environment,structural and hydrogeological conditions were conducive to the coalbed methane occurrence.Finally,the main factors that affected the occurrence of coalbed methane in the research area were the coalbed depth,the thickness of coal seam and the lithology of roof and floor.
