摘要(Abstract)：

根据镜下薄片观察、扫描电镜技术分析、流体包裹体测温及X线衍射分析,对苏里格气田苏59井区山1段储层岩相类型、岩石学特征、孔隙类型、储层物性和成岩作用等进行划分,研究山1段储层致密化成因和控制因素。结果表明:山1段为典型的致密砂岩储层,储层岩石组分以石英、岩屑为主,岩屑石英砂岩与岩屑砂岩是储层主要的岩石类型;残余粒间孔、次生孔隙和构造裂缝是山1段储层主要的孔隙类型,次生溶孔是山1段储层的主要储集空间;多种胶结物和泥质杂基以孔隙式胶结填充岩石,压实和胶结作用是导致储层致密化的关键因素;成岩后期的溶蚀和裂隙作用改善储层的物性,提高渗透率。该结果为苏里格气田59井区山1段储层预测提供地质依据。
