Within the framework of the program drawn up for the development of the nondestructive methods of studying the properties of heterogeneous materials, the studies were carried out to compare the data on the structure of xenon gas hydrate deposits, obtained by the x-ray microtomography method, with the speed of propagation of acoustic waves in them. The xenon gas hydrate was generated in a water-sandy medium at a temperature of +3°C and a pressure of 1 MPa in an experimental cell specially manufactured for these investigations. The obtained three-dimensional x-ray images of the structure with a spatial resolution of about 3 μm made it possible to clearly distinguish xenon gas hydrate against the background of the water-sandy medium. The results of investigations have shown that the hydrate is formed by enveloping sand granules, distributing unevenly in the body of the experimental cell. The data obtained by acoustic sounding are in good agreement with the data on the microstructure. A characteristic increase in the velocities of longitudinal waves from 1.048 km/s to 1.564 km/s, caused by the cementation of sand with xenon hydrate, is observed.
