摘要
本文结合自动测井相分析的问题,实现了自动相分析系统,并用聚类算法分析测井相与岩相的对应关系建立岩相库。文中分析了测井数据的特征提取、数据白化等关键问题,给出的模式识别具有自动筛选变量的功能。本文的方法应用于实际,取得了良好的效果。
Abstract
The system for automatic facies recognition has been developed on the basis of the automatical log facies analysis. And the clustering method has been used to analyze the ralationship between log facies and lithofacies. Then the lithofacies database is built up. An analysis of the feature extraction and data Whitening for well log is made, and the pattern recognition given can sercen variables automatically. Actual applications show that the method is effective.
