Outline of Final Research Achievements

We developed a high-efficient pore-scale two-phase numerical simulator by optimizing the robust lattice Boltzmann method using the innovative GPGPU（General Purpose Graphics Processing Unit）parallel computing technique. Based on the developed simulator, we adopted the digital rock approach to investigate the behavior of supercritical CO2 inside the pore space of reservoir rock during the CO2 geological storage project. Finally, our data provide useful information for understanding of CO2 storage mechanisms, optimizing the storage capacity, and evaluation of the storage risk.
