The merging of 3 D seismic data can be looked as the issue of optimum in different scale space mathematically, the key is how to realize the time variant merging.
三维地震资料拼接可看作是一个不同尺度空间的数学寻优问题，其关键在于如何实现时变拼接。
Because of influence of aperture of migration operator, the image of 3-d seismic data volume in space is smeared after migration, which is unfavorable for detecting the faults.
但由于偏移算子的孔径影响，经偏移得到的三维地震数据体在空间上被模糊了，不利于进行断层检测。
