Noise suppression is crucial for seismic data processing and interpretation. Both the supervised and self-supervised methods need to construct training data pairs, which is challenging for practical implementations. In this research, we propose an unsupervised denoising framework based on improved blind spot strategy, which operates directly on single noisy seismic data. Firstly, a global masker is introduced to mask the noisy data to obtain two masked data and input them into the denoising network, and then utilize the mask mapper to integrate all blind spots onto the same channel. Secondly, original noisy data is incorporated into the network training process to avoid information loss. Finally, a hybrid loss function with orthogonal convolution regularization constraint is adopted to further improve the performance of the network. Synthetic and field seismic data experiments show that the proposed method can make good balance between noise suppression and valid signals preservation.
