摘　　要：砂岩储层的孔隙结构特征是充分挖掘砂岩储集层产能和提高油气采收率的基础。运用电阻率测井资料能够有效、快速的分析储集层岩石的孔隙结构特征,为勘探开发提供有力的保证。根据毛管岩石导电物理模型,推导了利用电阻率测井资料计算砂岩储集层岩石孔隙结构参数的公式,并针对某油田砂岩储层进行了计算验证,效果较好。The pore structure character of sandstone reservoir is the base of exerting the productivity of sandstone reservoir and enhancing the recovery efficiency of oil/gas.It can be used to study the pore structure character of reservoir rapidly and efficiently by introducing the resistivity logging data,and provide a solid guarantee for the exploration and exploitation.According to the simplified physics conducting model,the formula can be conducted which can compute the pore structure parameter of sandstone reservoir.Moreover,based on the data of one oilfield,it carries out computation and gets a good result.
