ABSTRACT:
The invention is used to manufacture an inhomogeneous medium whose porosity and permeability undergo rapid transitions from one point to another of its volume, by juxtaposing different materials without creating a barrier. Such a transition is made by juxtaposing a first material and a second material with a different porosity to the first. One of them can be a rock sample such as sandstone for example, the other can be a composite material obtained by agglomerating pyrex powder for example, the whole being heated according to a specific temperature cycle up to a temperature (TR) lower than the melting point of the two materials but sufficient to achieve partial melting of one of the materials at the interface with the other material, but without formation of a continuous or discontinuous capillary barrier between them, or an interzone with preferred passage for fluids. Thus, different composite materials can be juxtaposed to constitute the inhomogeneous medium. The invention has applications to manufacturing a model representative of reservoir rocks in order to test assisted hydrocarbon recovery methods.
