Abstract
For most of the oil reservoirs, the total recovery factor for the primary and secondary stages only occupy by 20 - 40 %. The usage of CO2 injection method for those depleted reservoirs with suitable characteristics will considerably raise the recovery factor. The effectiveness of this CO2 injection process depends on quite a few of factors: reservoir pressure and temperature, characteristics of the reservoir rocks and the oil itself as well as the characteristics of the injected CO2. The factors will influence the interactive mechanism between CO2 and oil in the reservoir. This paper presents several results of enhanced oil recovery by CO2 injection. The simulation program of the front in CO2 injection enable the estimation and adjusting of the parameters of the injection process in order to reach the highest recovery factor.
