Abstract
The present application provides a vector denoising method and a vector denoising device for multicomponent seismic data, which relate to the field of seismic data processing technologies. The vector denoising method for multicomponent seismic data includes: decomposing multicomponent seismic gather data to obtain a plurality of small multicomponent seismic data; obtaining quaternary frequency domain seismic data by performing a quaternary Fourier transformation according to each of the plurality of small multicomponent seismic data; extracting frequency slices from the quaternary frequency domain seismic data in a quaternary frequency domain, and filtering the frequency slices by using a Cadzow filtering method to obtain filtered quaternary frequency domain seismic data; and performing an inverse quaternary Fourier transformation on the filtered quaternary frequency domain seismic data to obtain filtered seismic data of each component.
