| 摘 要： | 滇东黔西地区主要含煤层系为上二叠统龙潭组,为一些复式背向斜构造聚煤盆地。区内煤系发育,含煤面积2.58×104km2,煤变质作用为深变质和岩浆热变质。煤演化程度处于成熟—过成熟阶段。盖层封闭条件好,储气资源量为13078×108m3,生气能力和储气能力强。煤层含气量主要受控于煤岩的沉积环境、煤演化程度、埋藏深度、水文条件与构造条件。煤层储气能力是制约含气量大小的主要因素,它随着煤阶的增高和埋深的增加而增高,在埋深小于800m时最明显。煤层气含气量一般10.0～18.8m3/t.低煤阶时,丝质组煤层的储气能力大于镜质组的储气能力;高煤阶时,结果相反。镜质组含量高的煤层,其吸附能力较强,远景评价乐观。
