摘　　要：滨里海盆地K区块稠油油藏储层类型独特,目的油藏埋深较浅。针对哈萨克斯坦K区块开发后期含水上升快的问题进行研究,分析研究区开发后期水淹层测井响应特征,建立符合盐上稠油油藏的水淹层测井解释方法及水淹级别划分标准。结果表明,K区块为注入水水淹,水淹程度为中水淹,储层的孔隙度、渗透率、含水饱和度在水淹后均增大,泥质含量没有明显变化;电阻率随着水淹程度的增高而降低;水淹程度主要受沉积韵律及物性的影响。据此建立了定量判别水淹级别图版,适合泥质砂岩稠油油藏的水淹层测井解释。The reservoir type of heavy oil reservoir in block K in Pre-Caspian Bain is unique,and the buried depth of the target reservoir is shallow.In view of the problem of water cut rising rapidly in the late development period of K block in Kazakhstan,the logging response characteristics of watered flooded formation in the late development period of the study area are analyzed,and the logging interpretation method of watered flooded formation and the classification standard of the heavy oil reservoir in salt are established.The results show that the K block is side water flooding,and the degree of water flooding is medium water flooding.The porosity,permeability and water saturation of reservoir increase after flooding,and the mud content has not changed significantly.The resistivity decreases with the increase of water flooding.The flooding distribution is mainly affected by sedimentary rhythm and physical properties.A set of logging interpretation methods for the heavy oil reservoir of argillaceous sandstone are summarized.Based on this,a chart for quantitative discrimination of water flooded level is established,which is suitable for logging interpretation of water flooded formation in argillaceous sandstone heavy oil reservoir.
