摘　　要：研究解决三维复杂地表层析静校正耗时等问题的方法,采用快速初至时间拾取、快速表层模型折射反演、快速计算低频校正量及高频校正量、快速地表一致性和地表非一致性时差校正方法,实现了高效、高精度的快速初至波层析静校正,并经实际二维、三维资料处理证实了该方法及软件具有较高的效率,优于常规地震资料处理中所用的微测井加初至波静校正商业软件的处理效果。The paper studies the method to solve the problem of a great lot of time consuming in processing tomographic static correction with the 3-D complicated surface. The first arrival tomographic static correction with high efficiency and precision can be realized by using the methods of fast picking up the first break, fast refraction inversion of the surface velocity model, fast computing the low and high frequency corrections, fast surface consistency and surface non-consistency static corrections. The real 2-D and 3-D seismic data processing proved that the above-mentioned methods and the software have good results. They have an advantage of efficiency and precision compared with the log data and the commerce software of first break static correction used in the normal seismic data processing.
