CHRONOSTRATIGRAPHIC-DOMAIN STRATIGRAPHIC SEDIMENTARY CYCLE ANALYSIS METHOD AND APPARATUS

Title:

CHRONOSTRATIGRAPHIC-DOMAIN STRATIGRAPHIC SEDIMENTARY CYCLE ANALYSIS METHOD AND APPARATUS

Document Type and Number:

WIPO Patent Application WO/2024/036819

Kind Code:

A1

Abstract:

A chronostratigraphic-domain stratigraphic sedimentary cycle analysis method, comprising: performing multi-horizon tracking on seismic data by using horizon tracking technology, so as to obtain a chronostratigraphic body (101); transforming all horizons in the chronostratigraphic body from a time domain to a chronostratigraphic domain (102); extracting a depositional-hiatus sequence or a stratigraphic denudation amount sequence on the basis of endpoint positions of each horizon in the chronostratigraphic domain (103); converting the depositional-hiatus sequence or the stratigraphic denudation amount sequence into a stratigraphic sedimentary cycle curve (104); and obtaining a stratigraphic sedimentary cycle sequence on the basis of the stratigraphic sedimentary cycle curve (105). Further provided are a chronostratigraphic-domain stratigraphic sedimentary cycle analysis apparatus and a machine-readable storage medium. The chronostratigraphic-domain stratigraphic sedimentary cycle analysis method and apparatus can effectively improve the accuracy and objectivity of sequence stratigraphic analysis, and improve the efficiency and precision of seismic interpretation.
