Summary Numerical modeling is important in studying a variety of problems seismic wave propagation, many methods have been investigated for calculating the spatial terms equations, most widely used are classical finite difference (FD)method, Fourier pseudo -spectral (FPS)method and Finite Element (FE)method. It clear that each method has its own merits drawbacks. In order to study field characteristics 3D porous media mesoscopic scale, numerical simulation sedimentary rocks proposed combining with (FFD) White's patchy-saturation model. And scale established according actual formation. Finally, obtained by wave.
