摘要

///Forward simulating the crosswell seismic wave is one of important techniques that facilitate studying seismic wave propagation and identifying complex wavefield. Setting out from the two dimension crosswell seismic wave equation and combining the initial and boundary condition, the pair order accuracy difference scheme of random staggered grid was deduced and the realization method of non uniform difference grids was elaborated. On the basis of this, the finite difference forward simulation program of crosswell seismic wave equation was compiled.
