Three-dimensional fault identification method based on interactive feature fusion

The invention discloses a three-dimensional fault identification method based on interactive feature fusion, and the method specifically comprises the steps: obtaining a three-dimensional fault data set, each piece of three-dimensional fault data comprising three-dimensional synthetic seismic data and a corresponding fault label; expanding the three-dimensional fault data set by adopting a data enhancement mode, and dividing the expanded data set into a training set and a verification set; constructing an interactive feature fusion neural network, and performing training and verification to obtain a trained interactive feature fusion neural network, namely a three-dimensional fault recognition network; the interactive feature fusion neural network comprises encoders, decoders and interactive feature fusion layers connecting the encoders and the decoders, the number of the interactive feature fusion layers is determined by the number of the encoders and the decoders, and each interactive feature fusion layer i
