Numerical Simulation of Permeability Change in Porous Media by the Formation of CO_2 Hydrate

摘要

The permeability modeling considering CO_2 hydrate formation was successfully conducted for the porosity of 0.36. The modeling of permeability was conducted based on the Kozeny-Carman equation mainly on the specific surface area and the Kozeny coefficient. The modeling was done by using unidimensional values of these two parameters. The average error was contained under 5% however, for low Sw0 the modeling tends to have a fairly low accuracy.
