摘　　要：综合运用实测物性、解释物性、试油、压汞等资料，分别利用分布函数曲线法、试油法、束缚水饱和度法、最小有效孔喉半径法求取了东营凹陷滨南一利津地区沙四段砂砾岩体不同深度下有效储层的物性下限，运用回归分析方法求取了物性下限与深度之间的函数方程。在确定了研究区物性下限的基础上，分析了滨南地区和利津地区物性下限差异性的原因。利津地区储层由于裂缝发育、原油密度及黏度低、超压发育而具有相对于滨南地区较低的物性下限。With the help of the comprehensive data application of tested ＆ interpreted physical properties, oil pro- duction test, mercury injection and so on, the lower limits of the effective reservoirs are obtained at different depths of Es4 glutenite bodies in Binnan-Lijin areas of Dongying Sag by means of distribution function curve, production test, irreducible water saturation and minimum effective pore-throat radius methods; the functional equation between the the limits and depths is sought out by regression analyzing method. Based on the determined limits of the researched area, the reasons for the differences in the limits between Binnan and Lijin areas are analyzed. Because of the well-developed fractures, lower density and viscosity of the crude oil and overpressure development, the liraits in Lijin area are pretty lower.
