Latest Patents

Qiannan Wang holds a patent for an "Automatic seismic facies identification method based on combination of self-attention mechanism and U-shape network architecture." This patent outlines a comprehensive approach that includes obtaining and preprocessing post-stack seismic data to construct a sample training and validation dataset. The method involves building an encoder through an overlapped patch merging module with down-sampling function and a self-attention transformer module with global modeling function. Additionally, it describes the construction of a decoder using a patch expanding module with linear upsampling function, the self-attention transformer module, and a skip connection module with multilayer feature fusion function. The seismic facies identification model, which includes a Hypercolumns-U-Segformer (HUSeg), is iteratively trained with a hybrid loss function. This innovative approach allows for the input of test data into a trained identification model to obtain seismic facies corresponding to the test data.
