The technique of seismic pre-stack depth migration is used to correctly implement the complex structural imaging.
采用地震造前深度偏移技术，使复杂构造正确成像。
Therefore, the wave equation pre-stack depth migration, a method starting directly from the rolling surface, is discussed.
为此，探讨了直接从起伏地表开始的波动方程叠前深度偏移方法。
For enhancing the migrated imaging, these techniques, like DMO, migration velocity field smoothing and pre-stack depth migration, are used.
采用DMO、偏移速度场平滑、叠前深度偏移等技术提高偏移成像精度。
