摘要(Abstract)：

利用铸体薄片、扫描电镜观察、物性测试和压汞实验等方法,分析准中4区块中上侏罗统石树沟群储层的岩石学特征、孔喉特征和物性特征,研究沉积相带与成岩作用对储层物性的影响。结果表明:研究区储层岩屑含量高,成分成熟度较低;岩石类型主要为岩屑砂岩和长石岩屑砂岩,其中岩屑多为火成岩岩屑,矿物之间颗粒支撑,分选中等。储层物性整体上具有中—低孔中—低渗的特征,以粒间溶蚀孔隙为主,喉道多为分选较差的细喉型;局部方解石胶结物较发育,形成特低孔特低渗储层。沉积相带是优质储层发育的先决条件,在强水动力条件下形成曲流河边滩、三角洲分支河道等粗粒砂岩,泥质含量较低,物性较好。酸性流体对早期胶结物的溶蚀是优质储层形成的根本原因,压实作用和后期方解石连晶式胶结是粒间孔隙损失的主要原因,绿泥石黏土膜大量发育而堵塞喉道,造成局部储层渗透率较低。该结果对研究区下一步勘探具有指导意义。
