Abstract

Summary

The effect of elastic vibrations makes it possible to increase the permeability of the porous medium. In this paper we present a mathematical model of the permeability of a porous medium under wave action on it. This model is based on the hypothesis that a part of the absorbed sound energy is used to change the permeability of a porous medium. Experimental studies of the filtration process in an artificially created low permeable porous medium have shown that exposure to it by ultrasonic vibrations leads to a significant (2 times or more) increase in permeability. At the same time, after cessation of exposure, the permeability of the medium is reduced. The adequacy of the developed mathematical model is qualitatively confirmed by the experiments carried out, as well as by the results of other authors. To increase the effectiveness of wave action on productive layers of oil fields, it is necessary to provide the maximum amplitude in the necessary zones of the productive formation.
