CO2-Rich Associated Gas Re-injection Miscible Flooding Mechanism Research
In the CO2-rich reservoir, reinjecting associated gas cannot only achieve the purpose of enhancing oil recovery, but also can be achieved efficient use of CO2 resources and environmental protection of greenhouse gas processing. In this paper, through the formation fluid properties analysis of Hong Gang North Block, it shows the adaptability of re-injection associated gas. Beyond that, the P-x phase diagram of re-injection associated gas indicates the first non-hybrid camera contact management and equilibrium models with several contacts. Combining with this experimental results, it emulates the balance of the gas and liquid composition changes respectively from forehead to backhead contact on the basis of experimental data and then analyze the miscible phase of the mixed gas injection phase in the mass transfer process. Finally, contrast with the change of the pure CO2 injection, it can draw the conclusion that this two gas injection mass transfer management is immisiscrible and near misiscrible performance in this reservoir.
