Based on elastic seismic wave equation, wave field numerical modeling with high-order staggered finite-difference method is studied for different complicated geographical mode. First, elastic seismic wave equation is derived to obtain one-order stress-velocity equation, then, the equation is discretized by finite-difference method. This method is used to simulate three-level strata sloping downward model, fault model and oil layer model. The results indicated that the method is suit for simulating non-homogeneous media and complicated geographical mode, with high accuracy and efficiency.
