摘要

通过用分裂步傅里叶方法在频率波数域作波场延拓,实现了二维复杂地质模型的地震波场数值模拟,得到了合理的正演地震记录和偏移图像。结果表明该方法计算效率高,精度高,稳定性好,不受倾角限制,能适应速度纵横向任意变化,是一种比较好的地震波场模拟算法。
The wave field continuation was executed in frequency and wave-number domain through split-step Fourier algorithm.The numerical simulation of seismic wavefield corresponding to two-dimension involuted geologic model was then carried out.The results of modeling and migration were reasonable.It proved that the algorithm was quite efficient,accurate and steady,and it did not restrict on horizontal and vertical changes of medium velocity and layer dip angle.It's a relatively available seismic wave field numerical simulation algorithm.
