About propagation of seismic waves in block fluid media

Propagation of seismic waves in block two- and three-dimensional fluid media is investigated. For these media the effective models which are anisotropic fluids are established. For velocities of wave propagation in these fluid media the formulas are derived and analyzed. The particular investigation is performed in the cases that blocks with different fluids alternate along the coordinate axes or that blocks filled by a fluid are surrounded by blocks with another fluid. In the both cases the dependence of wave velocities in the whole of the medium on the differences of densities and of wave velocities in the fluid blocks is investigated.
