摘要
针对解决元素识别火山岩岩性主要依据人工经验进行元素选择,无法实现岩性自动识别的问题,提出一种准确率和智能化程度较高的方法,即根据元素相关矩阵及熵值计算结果来进行元素组合及选择的方法。通过大庆松辽盆地火山岩样品的图板分析实验而提出的组合和选择元素的方法,可确定各元素在岩性分析中的相互关系及重要程度,并在油田勘探录井现场应用中取得了较好的效果。
The element selection is mainly based on the artificial experience to solve the element identification of volcanic lithology and automatic lithology identification can not be realized,in view of these problems,the authors proposed a method with higher accuracy and intelligence,that is,the method of combination and selection of elements according to the result of element correlation matrix and entropy calculation.The method of combining and selecting elements by means of the chart analysis experiments of volcanic rock samples in Songliao Basin of Daqing can determine the correlation and importance of each obtaining element in lithology analysis.Better effects have been achieved in field mud logging of oilfield exploration.
