摘　　要：提出了一种新的利用常规测井资料计算地层含水饱和度的多元统计方法，它克服了常规方法中需要知道阿尔奇参数ｍ、ｎ、ａ、ｂ和Ｒ＿ｗ的困难，适用于注入水变化复杂的水淹地层．利用此方法的ＨＰＯＲ解释程序处理两口井。A new interpretation technique for calculating water saturation of strata by usinga new multivariate statistical analysis method is presented. The relationship of theformation,porosity,resistivity,mud filtrate resistivity, spontaneous potential and formationtemperature was developed.With this method, the Archie equation parameterts need notknow. As example is discussed.which shows a good promise for the new technique to be usedin the well log data intepretation for water flooded strata.
