In order to quickly identify the injection-production thief zones in high water cut period of sandstone reservoir developed by water injection, a Grey correlation-TOPSIS evaluation model was established to judge whether the thief zones existed. It uses SPSS software to test the KMO value and Sig value of each indicator to judge the correlation of each indicator. Then, the entropy weight method is used to determine the weight of each factor, and TOPSIS relative closeness degree and grey correlation closeness degree are calculated respectively. Afterwards, the model was applied to 20 wells and verified by field tracer monitoring method. The recognition accuracy was 85%. The method can provide certain basis for the later implementation of water plugging and profile control measures.
