摘要(Abstract)：

利用钻孔岩心观察、煤体结构频度统计及取心化验数据统计等资料,研究黔北煤田JP区块上二叠统煤层气的综合地质条件、含气规律及机制。结果表明:JP区块中、下煤组煤岩结构完整性优于上煤组的,东南翼优于西北翼的,煤层及围岩组合形式、构造应力释放方式决定煤储层结构完整性。煤层有机组分平均为79.29%,煤层镜质体最大反射率平均为3.08%,进入热裂解阶段晚期。煤层气组分以甲烷为主,储层平均含气量为12.17m3/t。煤层含气量受多种因素影响,其中与煤层埋深、热演化程度、高位热量等呈正相关关系,与煤层挥发分产率、地层倾角等呈负相关关系。三大主要控气要素——煤层埋深、地质构造稳定性和热演化程度决定煤层气的分布特征,相对宽缓的向斜西北翼为有利含气区。该结果为黔北地区的煤层气勘探提供指导。
