在前人研究的基础上,运用岩心、测井、铸体薄片、扫描电镜等资料,对博兴油田沙四上亚段储层的岩石类型、孔隙特征及孔隙结构等微观特征进行研究,并对储层物性控制因素进行了分析。沙四上亚段储层物性明显受沉积相和成岩作用的双重作用,其中坝砂储集物性最好;成岩作用对储层物性的控制作用明显,压实作用、胶结作用导致储层物性变差,溶蚀作用、交代作用使储层物性得到改善。 Based on the previous studies, the rock types, pore features and pore structure of the Shahejie formation in the Boxing oil field are studied by using core, well logging, thin cast film and scanning electron microscope The controlling factors of reservoir physical properties are analyzed. The physical properties of the Upper Shahejie Formation are obviously affected by both sedimentary facies and diagenesis, in which the reservoir properties of the dam sand are the best. Diagenesis controls the physical properties of the reservoir obviously. Compaction and cementation lead to the change of reservoir physical properties Poor, dissolution, explain the role of reservoir physical properties have been improved.
