对文东深层低渗油藏孔隙结构特征的研究采用了普通薄片、铸体薄片、扫描电镜、岩石物性、压汞试验等资料 ,提出研究区具 3种孔隙结构类型 ,并探索应用数学地质方法进行孔隙结构分类 ,对相同类型油藏的储层微观结构研究具有重要指导作用。 To study the pore structure characteristics of Wudong reservoir with low permeability, three kinds of pore structure types are proposed in the study area, such as ordinary thin slice, cast thin slice, scanning electron microscope, petrophysical properties and mercury intrusion test, and to explore the application of mathematical geologic methods The classification of pore structure plays an important guiding role in the study of reservoir microstructure of the same type of reservoirs.
