摘要

- method in order to model the flow of fluids in a porous medium multilayers cracked by taking into account the actual geometry of the network of cracks and the local exchanges between the porous matrix and the cracks in each node of the network and thus to allow a simulation of the interaction between the variations of the pressure and flow rate at the level of a well passing through the said mixture - the method comprises essentially a discretization of the fractured medium by means of a grid, with the meshes of the crack which are centered on the nodes to the various intersections of the cracks, each node being associated with a volume of the matrix, and a determination of the flows between each mesh of the crack and the associated matrix volume flow rate in a semi - permanent. - application to the tests of production wells for hydrocarbons, for example.
