摘　　要：针对常规分析方法在储层分类中存在的一些问题，本文筛选不同储层特征的最有代表性参数作为变量，利用综合聚类分析方法，对研究区油层组各主力储层进行了详细的综合分类评价。划分Ⅰ类储层115个，Ⅱ类储层105个，分类结果经已开发区证实吻合性强，对有利目标区的优选具有一定的指导意义。In view of the fact that reservoir analysis by general method tends to result in some problems, we use cluster analysis by some parameters with distinct formation characteristics of reservoirs to process classification and evaluation of main oil reservoirs in the study area. It shows that there are 115 reservoirs of type Ⅰ and 105 reservoirs of type Ⅱ. The classification result shows well consistency with production data of development area and has important instruction significance for selecting favorable zones.
