Abstract：The paper adopted staggering-grid high-order finite-difference algorithm of elastic wave equation in non-homogeneous medium to carry out numeric simulation, and the elastic wavefield separation is finished by solving divergence and rotation for elastic wavefield at each moment of forward process, in which the divergence field mainly is P-wave and rotation field is mainly converted wave and S-wave. The 2D cross-hole seismic elastic medium model of thin and alternating bed reservoir was created by using multi-scale gridiron and parametrization technique of model. The experiment of numeric simulation showed that the numeric simulation of elastic wave equation is able to truly simulate the cross-hole seismic wavefield, and the forward simulation coincides better with migration imaging result.
