摘要 滨南油田单16块沙三下亚段以厚层块状砂砾岩为主,夹薄层泥岩,测井解释难度较大。这里以取心井岩心分析为基础,分别研究砾岩、砂砾岩储层岩性、物性、电性和含油性相互之间的关系,分别建立了砾岩和砂砾岩孔隙度、渗透率、含油饱和度测井解释模型。应用所建测井解释模型,对研究区三十口井进行了二次解释。结果表明,分岩性建立的测井解释模型具有较高精度,应用该方法对提高砂砾岩油藏储层测井精细解释的准确性具有实际意义。 Logging interpretation is very difficult in reservoir of member III at Shahejie formation in Shan16 block of Binnan oilfield with heavy layer block-like glutenite. Based on cores analyses of coring well, the relationships of four reservoir properties (i.e.,lithology,physical property,conductivity and oil bearing) between conglomerate and glutenite formation are studied and the logging interpretation models of porosity, permeability and oil saturation in conglomerate and glutenite reservoirs with different lithologies are set up. Using the interpretation models, 30 wells in this area were reinterpreted and the results shows the interpretation models based on different lithologies have higher accuracy and important significant improvement in the accuracy of conglomerate reservoir interpretation and further providing foundation for geologic modeling and remaining oil redevelopment.
