The necessity and application of datum wave field continuation correction

摘要：

The surface elevation greatly fluctuation, the lateral variation of thickness and velocity of near-surface weathered layer, are the main reasons that cause complex wavefield and imaging difficult. The widely used vertical time shift static correction based on surface consistence can not solve this kind of problem. In this paper, using the velocity field obtained from tomographic inversion of first break, wave equation datuming method is used to a 2D synthetic model and a 3D field data, the result shows that wave equation datuming method is more effective than the conventional time shift static correction method
