Abstract
Based on mass conservation, foam total amount balance thought and foam properties characterization model, a foam flooding mathematical model with three-phase and five components is established and numerically solved. The explicit is used to solve the saturation equation and the implicit is used to solve the pressure equation in this model. By fitting the results of foam plugging capacity experiments and numerical calculation, the correctness of the model is verified. On this basis, the conceptual model is established to simulate and evaluate the sensitivity of influencing parameters of foam flooding plugging ability. The results show that: the plugging ability of foam system increases with the increase of foaming agent concentration. When the concentration of foaming agent is more than 0.3%, the resistance coefficient tends to steady; when gas-liquid ratio is 2:1, the foam plugging ability is the strongest. The plugging ability of foam system increases with the increase of permeability showing good permeability selectivity. If the permeability in the reservoir is higher than the profile, control capability will also be stronger.
