METHOD AND DEVICE FOR CHARACTERIZING ANISOTROPY OF PERMEABILITY OF A POROUS MEDIUM

摘要

P - The method to characterize the anisotropy, involves the injection into a point of a porous medium, permeable, saturated with a first fluid, a second fluid perfectly miscible with the first and of similar density, the detection of geometric characteristics of the invasion front of the second fluid at a given instant, by X-ray tomography in particular, the radial distance from the injection point at each point of the surface being proportional to 2RootK in the direction considered, the measurement of a only absolute value of permeability according to any reference direction and the global quantification of medium permeability values by considering a geometry of the invasion front. BR/ - Application to the study of permeable media and in particular rocks. / P
