摘要(Abstract)：

利用岩心、薄片、扫描电镜、X线衍射等资料,研究华庆B153井区长63重力流储层特征、发育控制因素及成因机制.结果表明:长63储层为典型的超低渗储层,岩石类型以长石砂岩和岩屑长石砂岩为主,储集空间以残余原生粒间孔隙为主,溶蚀孔隙次之;储层物性差,非均质性强,受沉积相、岩石矿物组成和成岩演化的综合控制,强压实作用、绿泥石胶结作用、碳酸盐胶结作用及弱溶蚀作用是导致储层低孔、低渗的关键成岩作用;根据不同成岩作用对储层物性影响的强弱程度,将超低渗储层成因机制划分为碳酸盐胶结低渗型、绿泥石胶结—溶蚀低渗型及强压实改造低渗型3种.应用孔隙度反演回剥方法,重建各成因机制低渗储层的致密化过程,为研究区有利储层预测提供地质依据.
