FLUID FILTRATION IN A MEDIUM WITH VARIABLE PERMEABILITY

Abstract

The paper considers a laboratory study of the interaction of a filtration flow with a poroelastic medium. As a result of the action of the filtration front, the skeleton is compressed, which leads to a change in permeability. The experiments were carried out on a two-dimensional optically transparent model at various pressures of the injected fluid. In the course of the study, a picture of the filtration process and deformation of the poroelastic medium was obtained, the velocities of the filtration wave, the dependence of the change in the speed of the filtration wave on time, and the width of its front were determined.
