Seismic deposition feature enhanced filtering method and device

According to the seismic deposition feature enhanced filtering method and device provided by the invention, hierarchical extraction of stratigraphic deposition information on seismic slices is realized through multi-scale two-dimensional wavelet decomposition, and seismic deposition information of a target geologic body can be enhanced and highlighted; meanwhile, the extracted seismic slice low frequency and corresponding residual errors (high-frequency components) both contain rich seismic deposition information, and the seismic deposition analysis precision can be improved through combined application of the high-frequency information and the low-frequency information; furthermore, the geologic body boundary can be clearly highlighted based on seismic slice information, and important guidance information is provided for fine description of transverse distribution of the reservoir; finally, the algorithm is simple and easy to implement, the operation efficiency is high, man-machine interaction is not needed,
