摘　　要：地震资料解释经常用到正演模型。常规的褶积模型不能模拟地震波的动力学特征。本文采用声波方程，通过四阶有限差分近似，实现了复杂地质构造零炮检距的数值模拟。文中同时展示了实际应用效果。A forward model is often used in seismic data interpretation. For the conventional convolution model cannot simulate the dynamic features of seimic waves, the paper chooses sonic wave equation to realize the numerical simulation of the zero offset in complicated geological structure by forth order finite difference approximation. At the same time, the applied effects have also been presented.
