- Abstract
The process of propagation of the Stoneley wave at the "water–water saturated or gas hydrate-saturated sand" interface is considered. To describe the process, the equations of continuity, state of the liquid, of momenta, wave equations, equations for the displacement of particles and components of stress tensors are used. As a result of finding analytical solutions in the form of a harmonic traveling wave for pressure, displacements, potentials for the vectors of longitudinal and transverse waves, a dispersion equation was obtained for determining the Stoneley wave velocity. The values of Stoneley wave velocity are obtained for different saturations of sand with water and gas hydrate. The dependence of the depth of penetration of a sound wave, of longitudinal and transverse waves into a liquid and a solid medium on frequency is determined. The idea of determining the thickness of the hydrate-bearing layer by the degeneration of the Stoneley wave with an increase in the duration of the latter is proposed.
