Abstract
In a process and apparatus for measuring the distribution of the concentrations of constituents of a centrifuged medium containing at least one fluid, during centrifuging, a mechanical signal, preferably a sound wave, is emitted from at least one emission point (19-22) in contact with or in the immediate vicinity of the medium (16). The emitted signal is received by at least one reception point (20-22) in contact with or in the immediate vicinity of the medium. For each emission-reception point pair, at least one propagation characteristic of the signal between the emission and reception points thereof is measured and, by an appropriate processor (15), the distribution of the concentrations of the constituents present in the medium is determined. A proposed application is the calculation of the relative permeability and capillary pressure curves of fluids in a porous medium in order to improve the working and operation of oil fields.
