【Abstract】 Three dimensional seismic wave forward modeling is an important tool in four dimensional seismic reservoir simulation. Three dimensional seismic wave forward can be performed by calculating spatial derivation of wave field using fast Fourier transform and calculating time marching based on the second order differentiating approximation. Seismic wave forward modeling for two simple three dimension models is given. The results show that the method is useful for three dimensional wave forward modeling.更多还原
