摘要
介绍了用测井资料进行相分析中的自动分层和岩性识别技术。采用的分层方法为最优分割法,岩性识别用统计分类中的贝叶斯判别法则。通过实际资料的处理解释,取得了与钻井地质剖面吻合良好的结果。
This paper presents a technique for automatic zoning and lithology identification from welllogs. It is necessary for the facies analysis. The technique used for automatic zoning is optimal seg-mentation, and Bayes decision principle is used for the lithology identification. This technique has beenused to process practical information and satisfactory consitency of interpretation results with geologicdata has been obtained.
