Dependence of Elastic Modules on Pore Pressure in Microinhomogeneous Medium

The paper is devoted to calculation of average elastic modules of microinhomogeneous medium. The new method, which is presented, is based on long-wave approximation, potential method of elasticity and averaging of medium parameters on orientation of structure. The using of fundamental solution of third kind (Weyl H.) as Green tensor gives a possibility to solve regular integral equations instead of singular ones. Velocities of P and S waves are increases with increasing of pore pressure, but increasing of S waves velocities is much more significant with respect to P ones, hence the ratio Vs/Vp is also increases.<br>Key words.
