制定砂岩储集层物性下限标准是准确判定其产油部位、划分油层有效厚度的基础工作之一。分析了影响物性下限取值的经济因素（主要有石油政策、经济指标、开发工艺、分析化验、资料丰度等）和地质因素（主要有储油层岩性、胶结物成分及含量、孔隙结构、原油性质、储集层压力、储集层裂缝等）。利用东濮凹陷濮城油田沙一段、沙二段砂岩储集层的取心井样品分析及单层试油等资料，采用５种方法（物性试油法，经验系数法，储油能力和产油能力甩尾法，钻井液侵入法，测试分析法）研究储集层的物性下限，并对各研究方法加以分析评价。据此确定了濮城油田合理的物性下限标准（孔隙度为１２％，渗透率为１．５×１０－３μｍ２）。影响储集层物性下限标准的因素较多，必须从多个方面反映各因素的影响，避免因方法单一导致下限标准取值偏差过大；不同地质条件和油田开发工艺条件下的物性下限标准有差别，应根据各油田的情况确定相应的物性下限标准。同一油田不同层位的储集层地质特征差别较大时，也须分别制定各自下限标准。当油田开发工艺、资料丰富程度等有较大变化时，应重新确定物性下限标准。图５表１参３（邹冬平摘）
It is one of the basic work to set the lower limit of physical properties of sandstone reservoirs to accurately determine the oil production site and divide the effective thickness of oil layers. The economic factors (mainly petroleum policy, economic indicators, development process, analytical laboratory, data abundance) and geological factors (mainly lithology, cement composition and content, pore structure, Crude oil properties, reservoir pressure, reservoir fractures, etc.). Using five kinds of methods (physical test method, empirical coefficient method, oil storage capacity and production capacity), using the data of coring well sample analysis and single layer test of sandstone reservoir of Shahejie Formation of Pucheng Oilfield, Dongpu Depression, Oil capacity flick method, drilling fluid invasion method, test analysis method) to study the lower limit of reservoir physical properties, and to analyze and evaluate each research method. Based on this, Pucheng Oilfield has determined the reasonable lower limit of physical properties (porosity of 12% and permeability of 1.5 × 10-3μm2). There are many factors that affect the lower limit of physical property of reservoirs. The influence of various factors must be reflected in many aspects to avoid the deviation of lower standard value due to single method. The lower limit of physical property under different geological conditions and oilfield development conditions is Difference, should be based on the situation of the oil field to determine the corresponding lower limit of physical properties. When the geological characteristics of different layers of reservoirs in the same oil field differ greatly, respective lower limit standards must also be formulated respectively. When the oilfield development process, such as the abundance of information have greater changes, you should re-determine the lower limit of physical properties.
