A Study on Factors influencing the effect of CO_2 Flooding in F48 Block

摘要

Using the Eclipse software to establish the component numerical simulator of formation crude, this paper analyzed the factors that influence the effect of CO_2 flooding, including 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 CO_2 flooding enlarged, and with the increasing relative density of the crude oil, the degree of reserve recovery of CO_2 flooding decreased. The stronger of the inlayer heterogeneity and the interlamination heterogeneity, and the higher of the permeability of the cross flow channel is, the lower level of CO_2 flooding degree of reserve recovery it tends to be.
