Claim 4:
5. A seismic imaging free gas structure identification system, comprising:
an acquiring and annotating module, configured to acquire a seismic imaging sample data set and annotate free gas structures of the seismic imaging sample data set to obtain an actual data training set;
an extending module, configured to use a generative adversarial network to extend the actual data training set to obtain free gas training samples, wherein the generative adversarial network comprises a generative network and a discrimination network;
a domain conversion module, configured to conduct domain conversion on original label data of the free gas training samples to obtain target domain expected output results;
a training module, configured to train a Bayesian neural network according to the free gas training samples and the target domain expected output results, to obtain a free gas structure identification model;
an acquiring module, configured to acquire actual seismic imaging data of a target work area; and
an identification module, configured to conduct, according to the actual seismic imaging data, identification by using the free gas structure identification model, to obtain free gas structure identification results.
