Abstract
The present invention provides a multi-mode dispersion energy imaging device and method for a four-component marine interface wave of an ocean bottom seismometer, belonging to the technical field of marine seismic exploration. The method includes the following steps: designing an marine interface wave artificial seismic observation system, designing a reasonable observation system according to the geological condition of the operation area to ensure the resolution of the imaging to perform the marine artificial source seismic operation carrying out the data preprocessing of the seafloor surface wave, and then carrying out the three-component seismometer Scholte wave and the acoustic guided wave dispersion energy imaging, and the one-component hydrophone acoustic guided wave dispersion energy imaging; superposing and normalizing the three-component Scholte wave dispersion energy spectrum and the one-component acoustic guided wave dispersion energy spectrum. The device is implemented based on the method above.
