摘　　要：利用岩心、测井、试气、分析化验等资料对东胜气田盒2+3段的岩性、岩石学特征、物性及含气性等进行分析,总结岩性、电性、物性及含油气性之间的关系。研究表明:东胜气田盒2+3段岩性主要为长石岩屑砂岩、岩屑长石砂岩、岩屑砂岩,储层属于低、特低孔隙度和低、特低渗透率储集岩,含气性较差;岩性控制着储层的物性,含气性主要由岩性、物性所决定;而储层电性是岩性、物性和含气性等特征的综合反映,是四性关系研究的桥梁和纽带。In this study, the Shihezi 2+ 3 Member was analyzed by some data from core, well logging, gas testing, and laboratory analysis. And its four-property(including lithology, and electrical,physical, and oil-bearing properties) relationship was summed up.Results show that(1) this member is mainly composed of feldspathic lithic sandstone, lithic feldspathic sandstone, and lithic sandstone;(2) it is a reservoir characterized by low to extra low permeability, low to extra low porosity, and poor gas-bearing property;(3)for this reservoir, the physical property is affected by the lithology whereas the gas- bearing property mainly relies on both lithology and physical property; and(4) the electrical property is not only a synthetical reflection of other three properties, but also a bridge to study the four-property relationship.
