Research on conductive mechanism and saturation model of the volcanic reservoir with complex pore structure

The complex lithology and pore system in volcanic reservoir result in the complex conductive features of the strata.The authors applied the electric conduction model proposed by Herrick and Kennedy to the volcanic reservoir in Wangfu area based on the theory of pore geometry.The parameters of the model were determined with core litho-electric experimental data in the volcanic rocks of Wangfu area,and a new electrical efficiency model suitable for the volcanic reservoir of complex pore structures was established.Using the new model to deal with the actual well data has achieved very good results.
