AI Technical Summary
In work areas with diverse surface types and complex near-surface structures, a single static correction method is unlikely to achieve satisfactory static correction results, leading to poor seismic profile imaging quality.
By calculating the static correction amount using multiple static correction methods, analyzing their advantageous regions and components, performing high- and low-frequency separation and regional splicing, and merging them into the optimal static correction amount for the entire region, the advantages of each method are fully utilized for static correction.
It improves the static correction effect in complex surface areas, enhances the quality of seismic profile imaging, and ensures the processing accuracy and precision of seismic data.
