Method of processing seismic image of the subsurface

摘要

The present invention relates to a method of processing seismic image of the subsurface. The method comprises determining two surfaces in the seismic image, the two surfaces being extracted from well data from at least on well in the subsurface; determining the dip components the first surface and the second surface; determining interpolated dip components based on dip components of the two surfaces; determining an interpolated surface based on at least the interpolated dip components; determining a density value based on a number of intersections of the determined surfaces with a column comprising said current pixel; determining a geological-time image, columns of said geological-time image are computed based on the density values of pixels of a corresponding column of the seismic image; and on the color value of pixels of the corresponding column of the seismic image.

1. A method of processing seismic image of the subsurface, said seismic image comprising pixels, each pixel having a color value,
wherein the method comprises:
determining a first surface and a second surface in the seismic image, the first surface and the second surface being determined based on geological information extracted from well data from at least one well in the subsurface;determining first dip components for pixels of the first surface and second dip components for pixels of the second surface;for each pixel of the seismic image between the first surface and the second surface, determining interpolated dip components based on at least the first dip components and the second dip components,for each pixel of the seismic image between the first surface and the second surface, determining an interpolated surface based on at least the interpolated dip components for pixels between the first surface and the second surface;for each current pixel of the seismic image between the first surface and the second surface, determining a density value based on a number of intersections of the determined surfaces with a column comprising said current pixel, said intersections being below said pixel in said column;determining a geological-time image, columns of said geological-time image is computed based:
on the density values of pixels of as corresponding column of the seismic image; andon the color value of pixels of the corresponding column of the seismic image.
