地震资料处理经常使用速度分析,为的是确定最佳动校正,以便给出一个好的共深度点剖面。当速度分析的密度足够高的时候,偏移所需的所有记录道被选排并且由拾取加以补充。我们正在描述用在偏移法中的各种程序,其本质部分由明确的速度简图所组成。 Seismic data processing often uses velocity analysis in order to determine the best kinematic correction to give a good co-depth point profile. When the density of the velocity analysis is high enough, all tracks required for the offset are selected and replenished by pick-up. We are describing the various procedures used in the migration method, the essence of which consists of explicit speed profiles.
