弹性波方程的VSP合成记录

VSP SYNTHETIC RECORD SIMULATED BY ELASTIC WAVE EQUATION

本文采用弹性波方程，通过有限差分近似计算，实现了ＶＳＰ合成记录的数值模拟。它与通常采用的声波方程相比，能获得更多波的信息。理论模型的计算结果验证了该方法的正确性。

By way of adopting elastic wave equation and finite difference approximation calculating method, the numerical simulation of VSP synthetic record is realized in the paper. Comparing with the usual used acoustic equation, the above equation can obtain much more acoustic information. The correction of this method can be verified by the calculated results of theoretical model.
