Method and apparatus for stratigraphic sedimentary cycle analysis in chronostratigraphic domain

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. The method and apparatus for stratigraphic sedimentary cycle analysis in the chronostratigraphic domain have the advantages of effectively improving the accuracy and objectiveness of sequence stratigraphic analysis, and improving the efficiency and precision of seismic interpretation.
