摘　　要：火山岩地层的岩性和孔隙系统复杂多样,使得地层导电机制复杂。文中基于孔隙几何理论,首次将Herrick和Kennedy提出的导电模型在王府地区火山岩进行应用。利用火山岩岩电实验资料,确定了模型中的参数关系,建立一种新的适用于复杂孔隙结构火山岩储层的导电效率模型。应用新模型处理实际井资料,取得了很好的效果。The complex lithology and pore system in volcanic reservoir result in the complex conductive features of the strata.The au- thors applied the electric conduction model proposed by Herrick and Kennedy to the volcanic reservoir in Wangfu area based on the the- ory 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.
