应用聚类分析对样品进行初步分类，分别为Ⅰ类Ⅱ类Ⅲ类流动单元。引入对应分析方法在平面图中分析样品点的空间分布规律和变量成因联系，进行地质解释和推断，研究认为：代表沉积作用的f1因子是流动单元分类的主要控制因素，代表成岩作用的f2因子是流动单元分类的次要控制因素。建立三类流动单元判别公式对样品进行回判，经分析认为判别函数有效，可以将判别公式应用到其他非取心井。该方法可为其他相似油田的流动单元研究提供依据和技术保障。
This paper applies cluster analysis method to primary classification of the samples and group them into Ⅰ, Ⅱ and Ⅲ flow units. By using the correspondence analysis method, the paper studies the spatial distribution pattern and genetic relationship of the samples on the plane graph in order to make geological interpretation and inference. The research suggests that the factor f1 which is related to sedimentation is the primary control factor of the flow unit classification, while the factor f2 which is related to diagenesis is the secondary control factor. Finally, the paper establishes the discriminant formulas to make judgment on the samples. The result shows that the discrimination function is effective and can be used in other wells. The research idea and method in the paper provide a theoretic basis and technical support for reservoir flow unit study in other similar oilfields.
