| 摘 要： | 利用测井资料进行岩性定量识别,分类方法的设计是决定分类结果好坏的关键。本文讨论了树分类器与产生式规则相结合的方法在岩性分类中的应用。利用数据完整的测井曲线参与树分类器的学习、判别工作,用树分类器进行岩性的“逐级识别”,不完整的特征交由定性规则处理,既实现了岩性的细分,且保证了分类的精度。

| Abstract: | In well logging interpretation, the design of method of lithology recognition is decisive for the result of classification. In this paper an application of the way of combining the dendritic classifier with specialist qualitation productive in lithology classification. Special attention was paid in precisely discerning different lithology character with classifier by successively distinguishing.Variance analysis and fisher discrimination were used for classification. The data-comple-te well logging curve joined in the procassing of study and discrimining of classifier. Whereas the data-incomplete well logging curve was dealt by qualitative rule. Then, It can guarantee the precise of recognition and fully utilization of the well logging materials. Finally, the paper gives a typical example, and it have also showed that |
