摘    要:
基于实测剖面资料,对下扬子巢湖-泾县地区上二叠统大隆组泥页岩储层特征进行了研究.结果表明,研究区大隆组厚12 ~ 35m,沉积时期处于水体贫氧-厌氧的静水还原环境,为一套黑色碳质硅质泥页岩建造.页岩中钙硅质脆性矿物含量为65% ~93%,粘土矿物含量5% ~ 30%,总有机碳含量在2.05%~13.9%,有机质成熟度为1.45% ~2%,属于成熟-过成熟演化阶段.大隆组泥页岩储层孔隙度为0.476%,渗透率为0.001×10-3 μm2,主要发育四类微孔(裂)隙:残余原生孔隙、次生溶蚀孔隙、次生晶间孔和微裂隙(缝).“高硅、高脆、高有机质丰度、孔隙发育”的四大储集特性表明大隆组海相黑色岩系具良好的勘探开发前景.

关 键 词:上二叠统  大隆组  页岩气  储层特征  下扬子巢湖-泾县地区
