Effect Evaluation of Foam System with Dripping Injection Foaming Agent in CO₂ Flooding Reservoir

Abstract:

In order to research the effects of the concentration of foaming agent and gas-liquid ratio on the steady seepage pressure of the foam, surfactants of HY-3 and HABS are used as foaming agents in this paper. And compared with the steady seepage pressure of the process of injecting CO2 individually and injecting CO2 accompany with dripping water, the results shows that these two kinds of foaming agents both can solve the problem of injecting gas breakthrough and injecting water difficultly, and the effect of HY-3 is better than that of HABS. By the evaluation experiment of the effect of the foam system which was applied in the ultra low permeability reservoirs with crack, it can be seen that these two kinds of foaming agents both can play the role of adjusting gas injection profile. The plugging ability and shunting effect of HY-3 is superior to that of HABS.
