【Abstract】 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.更多还原
