摘要
In Shanxi loess tableland areas,the surface geological conditions is complex,Low deceleration zone is unstable and has a great variation in elevation,so that the signal-noise-ratio (SNR) in seismic record is low and the static correction problem is severe.This paper shows it can be solve static correction problems well by combined using the tomographic static correction and refraction residual static correction with different wavelengthsbasing on summarizing the seismic data processing static correction.This solution improves the continuity of the stack section with seismic event in the actual production as well as the precision of exploration and the integral effect.
