The invention is a method of optimizing the injection of a fluid into a porous medium, using modelling the migration of the fluid within the medium having application for oil reservoir development. A reservoir model is constructed. In each cell of this the model, a PNM model representative of the pore network in the cell is constructed. The concentration of the fluid is then determined in each cell by solving the cell-scale reactive transport equation. Fluid concentration modifications at the level of the fluid/rock interface, at the pore scale, are therefore taken into account by means of the PNM models. Corrective coefficients for the reactive transport equation and a law between the permeability of the porous medium and the porosity of the porous medium are thus calculated. Finally, fluid injection is optimized as a function of the concentrations in each cell.
