文章在传统的模糊聚类分析的基础上，建立了一种新的多层次，多目标模糊综合聚类方法。在模糊聚类时，考虑到事物特征的复杂性和不均衡性，该方法将事物特征按其在不同层次上对事物的影响程度分类，再在各层次上确定不同特征的影响程度，最终建立起模糊等价矩阵进行聚类，它克服 了传统方法对多目标聚类的笼统性，使分析结果更可靠，该方法用于压裂酸化选井选层，其结果与现场情况相符，通过对比其它方法，该方法能够更准确地反映事物的特征，计算简单，实用，因而具有一定的现场实用价值。

Application of Multi-level Fuzzy Cluster to Well and Layer Choice f or Fracturing and Acidizing

Based on the analysis of the tradition al fuzzy cluster,a new multi level and multi object synthetic fuzzy cluster me thod is set up in this paper.According to this method,in view of the complexity and unbalance of the matter property,the property of the matter is classified ac cording to its effect degrees on the matter at different levels and then the eff ect degrees of different properties are determined at different levels,and final ly,the fuzzy equal matrix is set up to make clustering.This method can overcome the generality of the traditional method for multi object cluster and obtain a more reliable result.The result by using this method for choosing the well and l ayer for fracturing and acidizing tallies with the spot case.Comparing with othe r methods,this method can reflect more precisely the matter property and is simp le to calculate,having a certain practical application value.
