摘　　要：建立物性测井解释模型是为了提高子长油田测井解释的精度,对于储层描述和油层评价具有重要意义。利用测井数据,结合物性分析化验资料和取芯资料,先对储层的四性关系进行简要的介绍,然后在其基础上利用层点对应的读值方法建立适合子长油田长6储层的泥质含量和孔隙度的测井解释模型。渗透率的解释利用泥质含量进行分类和多参数的回归,其解释精度得到明显的提高。经过验证,所做关于子长油田长6储层物性参数的解释模型准确率高,效果好。The interpretation models of physical parameters are established to enhance the accuracy of log interpretation of Zichang oilfield,which has important implication for the formation assessment and reservoir description.Firstly,it briefly introduces the four property relations by using the logging data,core physical property analysis and core description.Then,the interpretation models of shale content and porosity of reservoir are established by using the layer-point reading data method based on the first step.The permeability interpretation is classified by shale content and then regression analyzed by multi-parameters,so that the accuracy of permeability interpretation is enhanced.The model validation test has been shown with high accuracy and satisfactory result.
