Abstract To address the climate change and reduce the emission of C02, C02 storage in the deep saline aquifer is one of the promising technologies. The visualization experimental system was set up to investigate the C02 migration mechanism during the displacement of supercritical C02 and water inside the core rock. From the experimental system, the experiment measured porosity, calculated the relative permeability-water saturation curve the water distribution will be achieved. The porosity can be measured accurately using MR technique. The fraction of effective porosity and movable fluid can be calculated, according to the T2 curve from MR. The MRI for core slice with the injection ratio of C02:H20=3:1 shows remarkable buoyancy effect.
