摘要: 通过岩心观察和薄片鉴定等资料,结合岩石物性、X射线衍射、总有机碳(TOC)含量及岩石热解和干酪根碳同位素等分析结果,对川中地区中三叠统雷口坡组三段(雷三段)的烃源岩和储层特征以及二者的配置关系进行了研究。研究结果表明:①川中地区雷三段2亚段发育一套以页岩和泥质灰岩为主的烃源岩,厚度为20~100 m,页岩平均TOC值为1.08%,最高可达4.01%,泥质灰岩平均TOC值为0.40%,有机质类型以Ⅱ1型为主,Ⅰ型次之,处于高成熟—过成熟早期阶段,生烃潜力较好。②研究区雷三段3亚段发育一套以粉晶白云岩和砂屑白云岩为主的储层,储集空间主要为晶间(溶)孔和粒间溶孔,平均孔隙度为4.05%,平均渗透率为1.1 mD,具有低孔中渗的特征。③雷三段2亚段烃源岩与3亚段储层形成了良好的源储配置关系,可形成“下生上储”、“自生自储”型油气藏,裂缝系统既为油气运移通道,也是重要的储集空间,上覆雷四段膏盐岩和须家河组一段泥岩均为有效盖层。
