Three-dimensional seismic fault automatic identification method

The invention provides a three-dimensional seismic fault automatic identification method. The three-dimensional seismic fault automatic identification method comprises the following steps: step 1, preprocessing actual data fault interpretation sample data; 2, enhancing actual data fault interpretation sample data; 3, carrying out the automatic recognition of a three-dimensional seismic fault; 4, designing a three-dimensional seismic fault automatic identification loss function; step 5, performing three-dimensional seismic fault automatic identification network training and verification; and step 6, carrying out practical application test on the three-dimensional seismic fault automatic identification network method. According to the three-dimensional seismic fault automatic identification method, a three-dimensional seismic fault network structure and a loss function are reconstructed and designed, it can be guaranteed that the corresponding relation between the spatial structure characteristics of actual sei
