摘　　要：本文以东濮凹陷胡状集油田沙三段储层为研究对象,通过岩石薄片、扫描电镜观察及粘土矿物分析等手段,对储层成岩作用类型及其对储层孔隙的影响进行探讨研究,明确了研究层段在埋藏过程中主要受压实、胶结及溶蚀作用的改造,其中溶蚀作用明显改善了储层的物性,主要表现为酸性介质下以碳酸盐胶结物、长石为对象的溶解,相应的在1950~2050m及2350~2500m发育2个溶蚀高峰带。In this paper,the reservoir of the third member of Shahejie Formation in Huzhuangji Oilfield of Dongpusag is taken as the research object,base on rock slice,scanning electron microscopy and clay mineral analysis,the types of diagenesis and its influence on reservoir pore are studied. It is clear that the study interval is mainly reformed by compaction,cementation and dissolution in the burial process. The dissolution has obviously improved the reservoir. Physical properties mainly show dissolution of carbonate cements and feldspars in acidic medium. Correspondingly,two dissolution peaks are developed at 1950-2050 m and 2350-2500 m.
