The division of reservoir flow unit is an important method in the development of remaining oil. A block of an oilfield in the eastern China is characterized as the feature of reservoir heterogeneity, complexity of produced layers between wells, difference of integrated water and complex flow zone under function of depositional environment, diagenesis and structural activity. We setup the sub\|consciousness function, based on 7 parameters of formation fluid factor, sandy ratio, permeability, porosity, onrush coefficient, permeability coefficient, and distribution density of mean interlayer. These 7 parameters are selected from 18 candidate parameters to indicate the depositional environment, diagenesis, tectonic factor, rock microscopic pore structure and reservoir physical property. The reservoir flow unit in the study area is divided into three types. We consider that the type Ⅱflow unit has the good potential for the remaining oil development. The reservoir flow unit division is well fitted with the actual development of remaining oil.
