通过对龙固井田研究区8个钻孔资料的分析,构造了新近系岩性组合特征系统聚类分析模型,分述了构建模型的几个重要步骤,并将欧式距离、标准欧式距离、马氏距离和明科夫斯基距离4种距离计算方法获得的聚类谱系图进行比较分析,发现在对于井田岩性组合特征聚类分析方面,欧式距离聚类分析更为符合矿井的实际情况。
Based on the analysis of 8 borehole data in the Longgu minefield, a cluster analysis model of the lithology combination system of Neogene is constructed. Several important steps of building the model are described. The Euclidean distance, standard Euclidean distance, horse The distance between them and the distance from the Minkovsky distance calculation method to calculate the clustering pedigree diagram were compared and found that in the cluster analysis of the Ida lithology combinations, the Euclidean distance cluster analysis more in line with the actual situation of the mine.
