摘　　要：该文从阿尔奇提出的地层因素及相对电阻率与孔隙度的经验公式入手,讨论了含水层的电阻率与渗透系数、导水系数的相关性。通过试验区利用井孔的抽水试验数据与井旁电测深解释的含水层数据(厚度、电阻率)分析对比,总结出利用井旁电测深资料计算水文地质参数的方法、步骤,并通过应用实例,进一步说明了利用井旁电测深资料计算水文地质参数的可行性和应用效果。Starting from the Archie＇s strata factors and the empirical formulas between the relative resistivity and porosity, it discusses the correlation between the resistivity of the aquifer and the permeability coefficient and coefficient of transmissibility. Through the analysis and comparison of borehole pumping test data with aquifer data （thickness, resistivity） of electrical sounding interpretation nearby well, it sums up the method and procedures to calculate hydrogeological parameters by electrical sounding data nearby well. With the application examples, it further explains the feasibility and application effects to calculate hydrogeological parameters by electrical sounding data nearby well.
