Claim 0:
1. A seismic imaging free gas structure identification method, comprising:
acquiring a seismic imaging sample data set, and annotating free gas structures in the seismic imaging sample data set to obtain an actual data training set;
using 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;
conducting domain conversion on original label data of the free gas training samples to obtain target domain expected output results;
training 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;
acquiring actual seismic imaging data of a target work area; and
conducting, according to the actual seismic imaging data, identification by using the free gas structure identification model, to obtain free gas structure identification results.
