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。

The study on pore structure characteristic for deep zone and low permeability reservoir in Wendong Oilfield which adopts information , such as thin section , casting thin section , SEM , rock petrophysical property , intrusive mercury testing. This paper puts forward three pore structure types on the basis of the types and characteristic researches of pores and throats. Meanwhile, some researches in which classification of pore structure with mathematical geology have been carried out . The study has important effect of guidance to the research of micro - structure for the same type reservoirs.
