Subtle oil and gas reservoir target enhancement interpretative processing method based on aging

The invention discloses a subtle oil and gas reservoir target enhancement interpretative processing method based on aging. The method comprises the following steps: (1) determining final result data through comparative analysis; (2) weakening a strong reflection layer in the result data, taking an input horizon as a reference, matching a local optimal wavelet, decomposing an original seismic record, extracting a strong reflection feature consistent with the optimal wavelet, eliminating the strong reflection feature and a seismic signal strong reflection layer, enabling a residual error to be minimum through multiple iterations, and subtracting the matched strong reflection record from the original seismic record; (3) combining dip angle guiding filtering, inverse Q filtering, median filtering and band-pass filtering of different frequency bands to highlight features of a target body; and (4) effectively identifying the target body hidden in the strong reflection layer by using wavelet transform and the tuning
