摘要: 利用薄片、扫描电镜、物性及压汞等资料,对金龙2地区三叠系上乌尔禾组二段(P3w2)低渗(含砾)砂岩储层孔隙结构及其影响因素进行了研究。结果表明:①乌二段属于低孔低渗储层,根据压汞曲线参数特征,将其孔隙结构划分为三类。②成岩作用控制了储层孔隙结构,定量计算结果表明,乌二段视压实率平均为53.54%、视胶结率平均为47.53%、视溶蚀率平均为13.84%、视微孔隙率平均为60.67%,表现为中等压实、中-强胶结、弱溶蚀、微孔发育等特征;压实作用、胶结作用、微孔隙发育主要控制储层孔隙结构的形成。③引入成岩综合指数来定量表征各种成岩作用的综合强度,其与储层孔隙结构参数(排驱压力、分选系数)以及储层品质因子(RQI)具有较好的统计相关关系,Ⅰ类储层成岩综合指数大于8%,Ⅱ类储层成岩综合指数为2%~8%,Ⅲ类储层成岩综合指数小于2%。因此,可以利用成岩综合指数定量评价储层孔隙结构。
