DYNAMICS OF ACOUSTIC WAVES IN A POROUS MEDIUM PARTIALLY SATURATED WITH A GAS HYDRATE

The propagation of acoustic waves in a porous medium partially fi lled with a gas hydrate was investigated with regard for the viscoelastic properties of the skeleton of this medium on the assumption that the gas hydrate is distributed homogeneously in the thin layer at the inner surface of pores of the medium. A system of equations defi ning the propagation of acoustic waves in a porous medium containing a gas hydrate is proposed. A dispersion relation has been derived for investigating the infl uence of different parameters of a porous medium on the propagation of acoustic waves in it
