The Influence Factors of Numerical Simulation on CO₂ Flooding in F-48 Block Low Permeable Oil-Field

Abstract:

In order to enhance the oil recovery of low permeable oil-field, this paper uses the Eclipse software to establish the component numerical simulator of formation crude, analyzes the factors that influence on CO₂ flooding, such as permeability, the crude oil relative density, the inlayer heterogeneity, interlamination heterogeneity, intrastratal cross flow channel and so on. The results show that along with the increasing of the permeability, the degree of reserve recovery of CO₂ flooding enlarged, and with the increasing relative density of the crude oil, the degree of reserve recovery of CO₂ flooding decreased. The stronger of the in layer heterogeneity and the interlamination heterogeneity, and the higher of the permeability of the cross flow channel is, the lower level of CO₂ flooding degree of reserve recovery it tends to be. The light reservoir which with poor development in vertical permeability or in the thin oil layers should be selected to use the CO₂ flooding, in order to guarantee a better development effect on the low permeable oil-field.
