提出了利用饱和度分析资料确定阿尔奇公式中参数的新方法 ,根据阿尔奇的两个基本公式推导出饱和度与电阻率和孔隙度的关系 ,将阿尔奇参数的求值问题转化为求解系数的一次多元方程问题。应用该方法对准噶尔盆地几个油田的实际饱和度资料进行了分析和计算 ,求出的参数均在理论值范围内 ,可以满足利用测井资料计算饱和度的要求。讨论了岩石物性和岩石润湿性对阿尔奇参数的影响。结果表明 ,由饱和度分析资料确定的阿尔奇参数变化范围很大 ,而通过岩电实验确定的阿尔奇参数则不能完全反映出参数变化范围。应用饱和度分析资料求解阿尔奇参数避开了求解地层水电阻率值的问题。饱和度的测定是在井场密闭良好的情况下进行的 ,但由于在测量过程中饱和度样品存在脱气、挥发等损失 ,使得实际测量值与原始值之间存在较大偏差 ,这势必影响饱和度资料的应用效果 ,因而要对饱和度测量结果进行校正 A new method of determining the parameters in Archie formula by using saturation analysis data is proposed. According to Archie’s two basic formulas, the relationship between saturation and resistivity and porosity is deduced. The problem of Archie parameter evaluation is transformed into solving coefficient A multiple equation problem. By using this method, the actual saturation data of several oilfields in Junggar Basin are analyzed and calculated, and the calculated parameters are within the theoretical range, which can meet the requirement of calculating the saturation by using well logging data. The influence of petrophysical properties and rock wettability on Archie parameters is discussed. The results show that the Archie parameters determined by the saturation analysis data have a wide variation range, while the Archie parameters determined by the rock experiment can not fully reflect the range of the parameters. The application of saturation analysis data to solve the Archie parameter avoids the problem of solving the formation water resistivity value. The determination of saturation is carried out in a well-closed well, but due to the loss of degassing and volatilization in the saturation sample during the measurement, there is a big deviation between the actual measured value and the original value, which will inevitably affect Saturation effect of the application of the data, so the saturation measurement results to be corrected
