Abstract
Provided are seismic data high-precision imaging method and device. The method includes: acquiring prestack seismic gather of work zone to be imaged; performing the multi-azimuth prestack migration processing on the prestack seismic gather by the fixed migration aperture for each imaging line in the imaging space, so as to obtain the set of multi-azimuth migration imaging profiles of each imaging line; and processing the set of multi-azimuth migration imaging profiles of the target imaging line by using the target neural network model, so as to obtain the high-precision migration imaging profile of the target imaging line. The target neural network model is a lightweight neural network based on the Transformer and the CNN, and the training target of the target neural network model is that the error between the output prediction result of migration imaging profile and the actual high-precision migration imaging profile result is smaller than the preset threshold.
