Latest Patents

One of his latest patents is an "Automatic seismic facies identification method based on combination of self-attention mechanism and U-shape network architecture." This method involves obtaining and preprocessing post-stack seismic data to construct a sample training and validation dataset. It includes building an encoder through an overlapped patch merging module with down-sampling function and a self-attention transformer module with global modeling function. Additionally, a decoder is constructed 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 utilizes these components, including a Hypercolumns-U-Segformer (HUSeg), and incorporates a hybrid loss function. The model is iteratively trained with a training and validation set, allowing for the input of test data to obtain corresponding seismic facies.

Another notable patent is the "Seismic time-frequency analysis method based on generalized Chirplet transform with time-synchronized extraction." This method achieves a higher level of energy aggregation in the time direction and effectively describes the local characteristics of seismic signals. It is applicable to both harmonic and pulse signals. The process involves applying the generalized Chirplet transform and calculating the group delay operator, followed by time-synchronized extraction on seismic signals. This approach allows for a more accurate representation of the boundary and heterogeneity structure of rock slices, facilitating subsequent seismic analysis and interpretation.
