Abstract: A method and apparatus for migration imaging of a viscous medium are disclosed. The method includes: determining a new compensation function of the viscous medium based on a phase compensation function of a seismic wave in the viscous medium and an established amplitude compensation function; performing Fourier transform on a seismic record of a receiver point of the seismic wave in the viscous medium to obtain a seismic record in a frequency domain; performing frequency division compensation on the seismic record in the frequency domain based on the new compensation function of the viscous medium to obtain compensated seismic data; and performing prestack depth migration on the compensated seismic data to obtain a migration imaging section of the viscous medium. According to the examples of the disclosure, the problem of compensation for absorption attenuation in an area with a small Q value is solved, and resolution of a seismic imaging section is increased.

Abstract: A method and apparatus for stratigraphic sedimentary cycle analysis in chronostratigraphic domain are provided. The method includes: performing multi-horizon tracking on seismic volumes by utilizing a horizon tracking technology so as to obtain a chronostratigraphic volume; transforming all horizons in the chronostratigraphic volume from time to the chronostratigraphic domain; extracting a sedimentary discontinuity or stratum erosion amount sequence based on end point positions of respective horizons in the chronostratigraphic domain; converting the sedimentary discontinuity or stratum erosion amount sequence into a stratigraphic sedimentary cycle curve; and obtaining a stratigraphic sedimentary cycle sequence based on the stratigraphic sedimentary cycle curve.
