针对渤海湾盆地大港油田小集油田小8-4-3井区储层非均质性强的特点,在单砂体储层研究的基础上,根据孔隙度、渗透率、含油饱和度、渗流系数和存储系数等参数的分布特点,从储层流动单元划分基本原理入手,应用模糊聚类分析技术,对比了不同流动单元的划分方法,优选出渗流系数和存储系数作为该类油藏储层流动单元的划分参数,划分出了4种流动单元类型,为研究区剩余油潜力分析提供了依据。
Aiming at the characteristics of strong reservoir heterogeneity in Xiao 8-4-3 well in Xiaoji Oilfield, Dagang Oilfield, Bohai Bay Basin, based on the study of single sand reservoir, according to the characteristics of porosity, permeability, oil saturation, seepage Coefficient and storage coefficient and so on. Based on the basic principles of reservoir flow unit division, fuzzy clustering analysis technique is used to compare the different flow unit division methods, and the seepage coefficient and storage coefficient are selected as the reservoir of this kind of reservoir The flow cell division parameters, divided into four kinds of flow cell types, providing the basis for the analysis of the remaining oil potential in the study area.
