摘要
地层水电阻率是确定储层含油饱和度的一个关键参数。根据自然电位测井数据与地层水矿化度之间的关系,在自然电位层厚校正、泥质校正、温度校正及油气影响校正基础上,可较为精确地确定地层水电阻率。该方法不用水层而直接求出地层水电阻率,并且计算结果与实际测试符合较好,具有准确、简便的特点。
Formation water electrical resistivity is a key parameter for confirming oil saturation of container rock.According to the relation of natural potential logging data and reservoir water salinity,based on the layer thickness emendation,slime emendation,temperature emendation and oil & gas effect emendation of natural potential,formation water electrical resistivity can be confirmed accurately.This method determines the formation water electrical resistivity without using the layer of water,besides,the results of calculation accord well with the practical testing with the characteristics of nicety and convenience.
