Abstract: Rock-electrical parameters are studied through many experiments and saturation interpretation are made in the
geological condition. The study is show that polymer solution have low mobility and conductivity；polymer Concentration
have effect on rock-electrical parameters，and shale content is lower and pore texture is better when concentration becomes
higher. Correspondingly，a is bigger and m and n are smaller. Sedimentary microfacies control product polymer concentration
directly. The Archies formula is suitable for polymer flooding reservoir，and saturation interpretation are made by using of
different rock-electrical parameters.

Key words: high porosity and permeability reservoir, polymer flooding, rock-electric experiment, rock-electrical parameters, interpretation method
