- Abstract
Comprehending deeply multiphase flow in saline aquifers is a precondition to solve the issues in the CO2 geological sequestration and the wettability heterogeneity is one of the main factors affecting the CO2 multiphase migration. In this paper, a Shan-Chen-type model (lattice Boltzmann method) is used to numerically investigate the effect of wettability heterogeneity on the CO2 migration path and ultimate saturation with the two typical heterogeneous models. The results suggest that the existence of wettability heterogeneity in porous media can thoroughly affect the flow path of CO2 and the ultimate saturation, so it is the factor that cannot be ignored in the numerical simulation and experimental analysis for CO2/brine systems.
