Abstract:CO2 flooding is the most popular recovery for oil production. It is significant to study the mechanism of the multiphase flow in porous media. In this study, experimental studies are carried out by using MRI technique to examine the detailed effects of miscibility and forces on CO2/n-decane flow in the porous medium and narrow channel. The displacing processes are conducted at various pressures and temperatures. The revolution of the distribution of decane and the characteristic of the two phase flow are investigated and analyzed. Difference between the two series tests was specified. Matrix has a great effect on the two phase flow. These experimental results give the fundamental understanding of tertiary recovery processes.
