摘　　要：克拉玛依油田砾岩油藏储集层岩性复杂、非均质性强、注入水矿化度变化大,水淹层定量解释较困难。通过多元回归建立分岩性的饱和度模型以及产水率、水洗指数等解释模型,结合地层电阻率变化特征,能够有效地提高水淹层测井解释的精度,满足实际应用要求。The conglomerate reservoir in Karamay oil field is characterized by complicated lithology, serious heterogeneity, varied salinity of injected water, which result in difficulty of quantitative interpretation of watered-out zones in it. This paper develops the models for lithology-based oil saturation, water cut and watered-out index by multivariate regression analysis. In combination with variation of the formation resistivity, the accuracy of well log interpretation of the watered-out zones can be effectively improved, thus meeting the demand of actural application of this technique.
