摘　　要：开发层系重组是高含水率油田二次开发的重要内容,为使其由定性分析定量化,提出了适用于高含水率油田层系重组的模糊聚类-F统计量-层系独立性检验(FFT)方法。综合考虑影响层系重组的主要地质和开发因素,通过基于模糊等价关系的模糊聚类计算得到了一系列初步分类,再引入F统计量计算得到较优的分类,然后通过层系独立性检验筛选形成符合油田实际的层系重组方案。应用于大港港西油田二次开发工程中,重组形成了港西二区N2mⅠ+N2mⅡ+N2mⅢ、N1gⅠ+N1gⅡ和N1gⅢ三套开发层系。Recombination of layer series of development is an important part in redevelopment project of a high water-cut oil field.For quantification of it from qualitative analysis,the fuzzy cluster-F statistics and independence test of layers （FFT） method suitable for such an oil field is presented.A series of preliminary and better classification are obtained by consideration of affecting factors on reservoir geology and exploitation,and the recombination scheme for this field is proposed in terms of the independent test and selection of layers.The FFT method is used in redevelopment project of Block 2 in western Dagang oil field and three layers of development of N2m I＋N2m II＋ N2m Ⅲ,N1g I＋ N1g II and N1g Ⅲ are given.
