摘　　要：砾岩油藏由于储集层岩石结构复杂、非均质性强、层间差异明显,同时由于油田开发年代跨度大,测井资料在参数和品质上都有较大差异,这些因素导致测井解释难度加大。以取心井岩心测试分析为基础,对年代较新的综合测井系列采用常规解释方法,对年代较早的标准测井系列引入砂层厚度、泥质含量、平均粒径等参数,并参考沉积微相等地质因素,在细分层系的基础上建立孔隙度、渗透率测井解释模型。应用结果表明,该方法建立的解释模型可靠,为水淹层解释及剩余油分布研究提供基础,同时该方法对开发中后期油田老资料的再利用有推广应用意义。Logging interpretation of conglomerate reservoir is very difficult in the west of district I area with multi-layer, complex rock structure, strong heterogeneity clear difference between layers and different log data . Based on cores analyses of coring well and sedimentary facies study, set up the logging interpretation models for different log data according layers. Using the interpretation models, 365 wells in this area were interpreted, the result of which shows the interpretation models based on different layers and logging data have higher accuracy and provide foundation for remaining oil redevelopment. The application significance of the interpretation models is the reutilization of early log data in late development stage of conglomerate reservoir.
