摘要 聚类分析是研究样本(或变量)分类的一种多元统计方法。以城壕油田西259井区为例,运用了聚类分析中的Q型分层聚类法,研究了长32储层的类型,并对样品进行归类,得出储层的空间展布规律。结果表明:该方法在储层评价中的应用是可行的,具有较强的合理性。 Cluster analysis was a multivariate statistical classification method for sample study(or variable),through analyzing the samples or the similarity between the phase variables,it was classified step by step.By taking Wellblock Xi259 in Chenghao Oilfield for example,Q-hierarchical clustering method of cluster analysis was used to study the type of C32 reservoir,and samples were classified,by which the law of spatial distribution of reservoirs was obtained.The results show that the method for reservoir evaluation is feasible with high rationality.
