摘要
山西煤炭资源和煤层气资源丰富 ,含煤面积分布广 ,煤类齐全 ,地质条件也较为复杂 ,为我们研究煤层气的生储条件提供了丰富的素材。在煤层气选区评价上 ,应选择含气量高、煤层厚度大、煤层气资源丰富且丰度较大的地区 ,同时考虑与煤的变质程度适中、水文地质条件有利于煤层气的赋存和排采 ,煤系盖层封闭好。
Coal resources amounts and coal seam gas resources are abundant in Shanxi.The area contains all kinds of coal and all over evevywhever.Geoglogy condrtion are more complicated too.It provide plenty of materials to research the conditions of emerging and reserving of coal seam gas for us. About evaluating on coal seam gas being seleted.We should select the area where contains gas amounts v ery much.coal bed thickness is bigger,and coal seam gas resources are enough and more,meanwhile considing many elements are just conform with the deteriorated conditions of coal.hydrology geology conditions are good at reserving and exploiting and discharging.The coal measures cover layer seals off well.The satu ration de gree of gas is high,etc.
