摘　　要：利用自然电位幅度差值ΔSP与视地层水电阻率Rwa交会图 ,确定复杂地层水系下高阻地层的地层水电阻率 ,计算储层含油饱和度 ,判断油水地层。该方法在苏丹南部穆格莱德盆地FL凹陷成功的应用 。The cross plot between difference of SP log and appearent formation water resistivity is used to determne formation water resistivity under com plex formtion water system in this artic1e. Then, the oil saturation of the reservoir is calculated to identifies oil and water formation. The successful example of the technique in FL sag is also intro duced.
