摘　　要：根据岩心分析及测井资料,明确东濮凹陷濮卫地区盐间非常规储层的岩性、物性特征。同时运用试油法确定了该地区盐间非常规储层有效储层物性下限,研究表明,有效储层孔隙度、渗透率下限分别为8.0%、0.22mD。在物性下限研究的基础上,探讨了盐间非常规储层有效性的控制因素。研究结果表明,裂缝、泥质含量及碳酸盐含量是影响濮卫地区盐间非常规储层有效性的重要因素。该区盐间非常规储层泥质含量、碳酸盐含量上限值分别为17.5%、27.0%。In terms of the data of core analysis and well-logging the lithological and physical characteristics are confirmed.At the same time the physical properties lower limit of inter-salt unconventional effective reservoir of Puwei Area in Dongpu Sag are also given by using oil testing method.It is revealed that the lower limit of porosity and permeability are 8.0% and 0.22 mD respectively.Based on the study of physical properties lower limit controlling factors of inter-salt unconventional reservoir effectiveness are discussed.It is suggested that fractures,shale content and carbonate content are important factors that influence the effectiveness of inter-salt unconventional reservoir of Puwei Area.It is known that the upper limit values of shale content and carbonate content are 17.5% and 27.0% respectively.
