应用模糊聚类分析法确定地层对比中的关键层

Application of Fuzzy Clustering Method to the Determination of a Key Layer in Stratigraphic Correlation

为提高测井曲线井间对比的质量和自动化程度,减少人工干预和制约,提出了应用模糊聚类分析法自动确定地层对比中各井关键层的方法,并与寻优追踪法和有序元素最佳匹配法相结合,形成了较为完整的测井曲线井间对比系统。通过资料试处理表明,该方法可以准确地确定出各对比井关键层。

In order to improve quality and automatization of log presentation analysis between wells, and cut down man-made noise, a method of fuzzy clustering to determine automatically a key layer in stratigraphic correlation between wells is presented Combining with optimal pursue and sequential elements best match methods, a integrated stratigraphic correlation system between wells is developed in this Paper. The results of processing for practical data show that the key layer can be determined accurately by the method.
