Abstract
The data of geology, well logging, log and core analysis are comprehensively used for analyzing the characteristics of Es_3 low resistivity zones in Pucheng Oilfield. A new method is proposed for evaluating the composite lithology and mixed formation water in the low resistivity zones, the established interpreting criterion is used for the secondary process of logging data of Es_3 in Pucheng Oilfield, evident geologic effect is achieved , by which the new method is proven for easy and effective application.
