摘　　要：通过分析研究油层水淹前后测井响应的变化特征,总结水淹后油层岩性、物性、电性、含油性和地层水矿化度的变化规律。对于特低渗透率油藏的水淹层解释,主要采用新、老井叠合法,经过分析对比确定油层水淹程度。这种方法在研究区实际应用过程中具有较高的符合率,能够准确识别水淹层,排除了储层岩性、物性、润湿性等因素影响。Based on the analysis and study of the change characteristics and logging response of the reservoir before and after water flooding,the change rules of lithology,physical property,electrical property,oil-bearing property and formation water salinity of the reservoir after water flooding are summarized.For the water flooded reservoir interpretation of ultra-low permeability reservoir,new and old well superposition method is mainly used to determine the water flooded degree of reservoir through analysis and comparison.This method can eliminate the influence of reservoir lithology,physical property,wettability and other factors.

关 键 词：水淹前后变化特征 测井响应 水淹层解释评价 水淹程度
