Research and Applicability of Refraction Static Correction and Tomographic Inversion Static Correction

摘要

Refraction static correction and tomographic inversion static correction are commonly used in seismic data processing. It is often believed that the effect of tomographic inversion static correction is better than the effect of refraction static correction. But it is not true. This paper summarized the applicable conditions, advantages and disadvantages of these two methods. In low mountains areas, the effect of tomographic inversion static correction is better than the effect of refraction static correction. However, in loess tableland areas, the effect of refraction static correction is almost the same as the effect of tomographic inversion static correction. It can't reflect the advantages of tomographic inversion static correction. All of the above is proved from models and sections. So each technique must meet its applicable conditions to reflect its superiorities. Integrated application of static correction methods is effective to solve the complex surface statics problems.
