1results about How to "Reduced dynamic range" patented technology

This invention relates to the field of seismic signal exploration technology, specifically disclosing a method and apparatus for single-shot energy correction in seismic data contiguous processing. The method includes: performing geometric diffusion energy compensation processing on all single shots across the entire area to obtain single-shot data; generating single-shot energy attributes corresponding to each shot across the entire area based on the single-shot data; smoothing the text format of the single-shot energy attributes to generate single-shot energy adjustment factors; and performing amplitude correction processing on the original single shots based on the single-shot energy adjustment factors. This invention, by statistically analyzing the energy attributes of the original single-shot data, smoothing the energy attributes across the entire work area, extracting energy correction factors for each single shot, and applying these correction factors to the original data, thereby reducing the significant energy differences between blocks. It adaptively reduces the dynamic range of energy distribution in the data, providing good data preparation for subsequent surface-consistent energy compensation methods, and achieving consistency between changes in data energy intensity and objective changes in subsurface lithology.
