摘　　要：利用物性资料、岩石薄片、扫描电镜及能谱、阴极发光等资料,开展了松辽盆地大庆长垣—三肇凹陷扶余油层致密储层岩石学、矿物学和孔隙特征研究,确定了扶余油层成岩作用类型,并建立了其成岩序列。压实作用表现为中等强度压实,胶结作用类型主要为方解石胶结、石英自生加大、自生高岭石及少量绿泥石,交代作用主要表现为方解石交代长石和石英加大边,方解石胶结物被溶蚀的现象不常见。基于碎屑颗粒、各种胶结物及孔隙之间的接触关系和产状,建立了扶余油层的成岩序列。Using physical data,SEM and energy spectrum of rock sheets,the petrography,mineralogy and pore characteristics of dense reservoir of Daqing Changyuan-Sanzhao depression in Songliao Basin were studied,and the type of diagenesis was determined and the diagenetic sequence was established.Compaction action is moderate strength compaction,the type of cementation is mainly calcite cementation,quartz self-growth,kaolinite and a small amount of chlorite,metasomatism action is mainly manifested as calcite metasomatism feldspar and quartz increased edge,the dissolution of calcite cement is not common.Based on the contact relationship and production between debris particles,various cements and pores,the diagenetic sequence of Fuyu oil layer is established.
