CO₂ hydrate formation during the injection process in an oceanic reservoir offers extended sequestration capacity and extra sealing. However, review of the literature reveals that the role of injection strategy on hydrate distribution remains unclear. Therefore, in this work, the reservoir was rebuilt first using muddy-silt-type marine soil from the station of LW3 in the northern part of the South China Sea. Then, the characteristics of hydrate distribution in the reservoirs using water/CO₂ injection mode were compared, and their effects on CO₂ sequestration were analyzed.
