【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,通过分析各样本或变量间的相似性逐步归类。本文以古龙油田为例,运用了聚类分析中的Q型分层聚类法,研究了古龙油田葡萄花油层组沉积成岩相的类型,并对样品进行归类,得出沉积成岩相的空间展布规律。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。更多还原

【Abstract】 Cluster analysis is a multivariate statistical methods of the study of samples(or variable) classification,by analyzing the similarity of different samples or variables,then gradually classified.In this paper,the Gu Long oil field is taken as an example.Applying the Q Cluster of cluster analysis,we study types of sedimentary facies of the putaohua oil set in the Gulong oil field,and classify samples,then obtain the spatial distribution pattern of sedimentary facies.The results show that: the method applied in the reservoir evaluation is feasible and high reasonable.更多还原
