Lattice Boltzmann method simulation of CO2/brine two-phase transport in porous media

Year: 2024

Type: conference-paper

Abstract: In recent years, global average temperature has been increasing. The main cause of this phenomenon is the continuous increase of CO2. Therefore, it is urgent to reduce CO2 emissions. CO2 storage in deep aquifer is an effective means to reduce CO2 emissions. Based on this, lattice Boltzmann method is proposed in this article to study the two-phase CO2/brine transport process in the deep saline aquifer. Simulation results show that the finger-in phenomenon is intensified with the increase of capillary number Ca and contact angle θ. Meanwhile, the CO2 saturation will also increase at the end of the repulsion when the capillary number Ca increases, while the CO2 saturation will decrease when the contact angle θ increases.
