摘　　要：吴起油田长官庙油区长4+5储层是主力油层,为进一步挖掘开发潜力,利用岩心薄片、压汞、测井及岩心等资料,从岩石学特征、物性特征,以及渗流特征等方面研究目标储层,并对储层进行了分类评价。最终得到,长官庙油区长4+5储层主要为浅灰色、灰色岩屑长石砂岩和长石砂岩,以细砂岩为主,整体上属于特低孔、特低渗储层,润湿性为弱亲水,储层类型有Ⅱb、Ⅲa、Ⅲb、Ⅳ。Chang 4+5 in the Zhangguanmiao oil area of Wuqi oilfield is the main reservoir.In order to further explore the development potential,using analytical data such as core flakes,mercury pressure,logging,and cores to do the reservoir characterization with in the study area in terms of petrological features,physical properties,pore structure,seepage characteristics,and other aspects and conduct the reservoir classifications and evaluations.Finally,the Chang 4+5 reservoir in Zhangguanmiao oil area is mainly composed of light grey,grey lithic feldspar sandstone and feldspar sandstone,mainly fine sandstone,as the whole belongs to the ultra-low porosity and ultra-low permeability reservoir and the wettability is weak hydrophilic,The reservoir in the study area are Ⅱb,Ⅲa,Ⅲb and Ⅳ.
