摘要
在实现地震资料的全三维处理中,叠后三维一步法偏移是至关重要的一个步骤。本文通过对一块浅海资料的一步法和两步法偏移处理结果的对比,说明一步法偏移在改善陡倾角成像、确定断层位置和构造方面有良好的效果。
One-pass 3-D migration after stack is essential to full 3-D processing of seismicdata. The comparison between one-pass and two step migration results of the sameseismic data from a shallow sea area shows that one-pass migration brings better ef fect-in improving both steep seismic wave images and the determination of fault orstructure position.
