摘要：

Saline aquifer under the seafloor is one of major options for the reservoir of CO2 geological storage. In case of a seepage, previous researches indicate that behavior of seeping CO2 significantly depends on flow rate and bubble size, which are expected to be controlled by gas migration through unconsolidated marine sediments. In this study, gas-liquid-solid three phase flow 3D simulator was developed by coupling of LBM-DEM to predict those phenomena. Simulation results indicate that channel forming through unconsolidated layer affects the behavior of gas seepage and bubble forming, and the resultant bubble migration and dissolution in the sea-water column.
