| 摘 要： | 东营凹陷南斜坡孔店组岩石类型以岩屑长石砂岩为主 ,长石砂岩和岩屑砂岩次之 ,其中岩屑长石砂岩含量超过 90 %。砂岩成岩作用包括压实作用、胶结作用、溶蚀作用、交代作用等 ,其中胶结作用使储层原生孔隙迅速变差 ,而溶蚀作用是次生空隙发育的主要因素。孔店组砂岩成岩作用进入晚成岩A期 ,期间经历了早成岩A期、B期。影响成岩作用的主要因素为构造演化背景、岩石成分、沉积环境、孔隙流体性质等。

| Abstract: | The rock types of Kongdian Formation include sedimentary rocks such as lithic arkose sandstone, feldspar sandstone or lithic sandstone in southern slope of Dongying depression, and the content of lithic arkose sandstone is over 90%. The reservoir sandstones have undergone compaction, cementation, dissolution and replacement, cementation of which made reservoir worse, and dissolution is the major factor influencing secondary porosity. Diagenetic stage was A period of late diagenesis, which went through A period and B period of early diagenesis. The main factors influencing the diagenesis of sandstone reservoir are evolution of tectonic background, rock component, sedimentary environments and nature of pore fluid. |
