Three-dimensional seismic data quick edge detection method based on time domain generalized Hilbert conversion

The invention discloses a three-dimensional seismic data quick edge detection method based on time domain generalized Hilbert conversion. The method includes the following steps that an objective interval of three-dimensional seismic data serves as a research object, the three-dimensional seismic data are input, a three-dimensional equitime slice calculation method is adopted, and a two-dimensional equitime slice of the objective interval is calculated; two one-dimensional Ehrlich's factors of a time domain are calculated to obtain an edge detection result of the current equitime slice; an ultimate edge detection result of the current slice is obtained; equitime slice numbers are replaced, and all the equitime slices are calculated; according to the positions of the equitime slices in the objective interval, edge detection results of the equitime slices are stored to obtained an ultimate three-dimensional edge detection result of the objective interval. The method has high edge detection accuracy, is high in calculation efficiency and guarantees that all sampling points are located on the respective equitime slices; underground geological conditions closest to reality are obtained, and meanwhile, restoration of the edge detection result is facilitated.
