Summary:The invention belongs to the technical field of sandstone type uranium mine seismic exploration and interpretation, and particularly relates to a robust sandstone type uranium mine frequency division seismic attribute-based river channel identification method, which comprises the following steps of: inputting original three-dimensional post-stack seismic data containing noise; initializing spectrum analysis, and determining low, medium and high frequency points of frequency division; calculating the GLCT time-frequency spectrum TFR (t, f) of each channel of (x, y) seismic data s (t); performing spectrum equalization on each channel of TFR (t, f) of the frequency division tuning data body; after spectrum equalization, three-dimensional GLCM is extracted based on the frequency division amplitude bodies of the low frequency band, the middle frequency band and the high frequency band, or two-dimensional GLCM is extracted based on the extracted target layer slice; the texture attribute of the GLCM of each frequenc
