| Abstract: | Realistic representation of the earth may be achieved by combining the mechanical properties of elastic solids and viscous liquids. That is to say, the amplitude will be attenuated with different frequency and the phase will be changed in the seismic data acquisition. In the seismic data processing, this effect must be compensated. In this paper, we put forward a visco-acoustic wave propagator which is of better calculating stability and tolerable calculating cost (little more than an acoustic wave propagator). The quite good compensation effect is demonstrated by the numerical test results with synthetic seismic data and real data. |
