| 摘 要： | 东营凹陷北部陡坡带西段沙四段储层是砂、砾岩为主的近岸水下扇沉积体。其储层岩石结构成熟度和成分成熟度均较低。运用化验资料对其成岩作用进行研究发现，储层主要经历了压实作用、胶结作用和溶蚀作用，目前处于晚成岩A期。在此基础上，分析了成岩作用对储集物性的影响，定量恢复了储层孔隙空间的演化史。

| Abstract: | The 4th member of Shahejie formation in the west of northern steep slope of Dongying sag is a nearshore submarine fan reservoir, whose lithology is mainly sandstone and conglomerate. The reservoir is of the li-thological characteristics of low composition maturity and low structure maturity. Its diagenesis is studied u-sing many kinds of laboratory test analytic data. Diage-netic evolution stages are divided through data of clay mineral evolution, vitrinite reflectance, etc. Study shows that compaction, cementation and dissolution had happened mainly in the reservoir evolution and the reservoir is in a stage of post diagenesis. Based on these studies, influence of diageneses on reservoir physical properties is analyzed and pore evolution history is recoveried quantitatively. |
