| Abstract: | This paper analyzes the stability and convergence of the seismic wave ifeld by using the high-order staggered-grid limited differential method of joining the absorbing boundary condition and attenuating zone to simulate the elastic wave equation. The results of the simulation of both isotropic-and anisotropic-medium models show that the grid frequency dispersion of the high-order differential wave equation simulation is smaller and more accurate. Therefore, this method should improve the efifciency of seismic prospecting and of the associated data interpretation. |
