Method and device for measuring the concentration of at least two fluids in a porous medium

摘要

The invention relates to a method and a device for measuring the concentration of at least two fluids in a porous medium 1. Such devices are particularly intended for the oil industry. The device of the invention includes n pairs of acoustic transceivers (transmitters/receivers) 2, defining measurement volumes zi j k. The computation means calculate the concentrations Ci j k on the basis of the set of times tn and visualisation means provide representation of the concentrations Ci j k. <IMAGE>
