摘要
A method of the invention provides improvement in the quality of coupled simulations between geomechanical and reservoir models by constructing a geomechanical model of an underground zone intended to be coupled with a reservoir model allowing simulation of fluid flows in the zone, from a geological model of the zone discretized by a fine grid. Geomechanical properties are associated with the various cells of the geological model on the basis of experimental data, the underground zone is discretized by a geomechanical grid with larger cells than the geological grid, and a scale change is applied to the geomechanical data included in the geological model in order to define equivalent geomechanical properties at the scale of the geomechanical grid of the zone.
