A Study on the Contaminant Transport in Low Permeability Porous Media
In view of the existing the starting pressure gradient in low permeability porous media, the law and character of contaminant transport under different starting pressure gradient (SPG) are compared, and the course of contaminant transport in saturated low permeability porous media is simulated applying mathematical model. The results indicate that SPG is different in different texture core and the bigger the SPG is, the lower the seepage velocity is. The influence of hydrodynamic dispersion on contaminant transport is more obvious. By simulating, it can be seen that the convective diffusion equation can simulate the course of contaminant transport in low permeability core accurately.
