摘要
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。
Concerning about the heterogeneity of the reservoir in the Xiao 8-4-3 wells of Xiaoji oilfield,we classified the flowing unit of reservoir based on single sandstone body.According to the distribution of porosity,permeability,oil saturation,permeable coefficient and storage coefficient,we use the Fuzzy Cluster Analysis to compare the different divisions of flowing units,and then preferentially select the permeable coefficient and storage coefficient as a key parameter of reservoir flowing unit division.Four types of divided flowing units would give a basic support for evaluation of remaining oil reserve.
