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.
