摘　　要：针对油藏地质中油水层判别问题,提出了一套利用测井资料综合判别油水层的ISODATA方法,建立了此方法的数学模型,并编制了相应的软件。运用该方法对地质情况复杂的海拉尔盆地乌尔逊地区的测井资料进行处理,总符合率达88.0%。结果表明该方法可提高油水层识别的精度。In this paper a series of ISODATA methods to identify water/oil bed based on logging data are established. The mathematical models about these methods are built and corresponding software is composed. These methods are applied to process the complex logging data of Wuerxun area in Hailaer basin, and the total coincidence rate can reach 88.0%. The results prove that these methods can improve the identification accuracy.
