In this paper, we propose a new method for automatic stacking velocity analysis, using AG-UNet3+ to construct deep neural network architecture to pick velocity spectrum. Compared with the conventional manual velocity spectrum picking method, our method is less affected by seismic noise, multiple waves, etc., and has better applicability under complex geological conditions. Compared with conventional deep learning methods, our neural network structure combines the full-scale skip connection and attention mechanism, which improves the generalization ability of the network and the ability to identify energy clusters in the velocity spectrum. The application results of actual seismic data show that our method can automatically pick up velocity spectrum in complex structural zones, and the precision of superimposed velocity field modeling is higher than that of conventional methods.
