Title:
CONTINENTAL SHELF PROFILE DETERMINING METHOD AND APPARATUS BASED ON NON-DELTA TRANSGRESSION
Document Type and Number:
WIPO Patent Application WO/2022/228450
Kind Code:
A1
Abstract:
The present invention provides a continental shelf profile determining method and apparatus based on non-delta transgression. The continental shelf profile determining method based on non-delta transgression comprises: establishing a continental shelf profile two-dimensional model according to the amount of sediments supplied by a river in a target work area and the rate of sea level rise; in a spatial rectangular coordinate system, solving the continental shelf profile two-dimensional model so as to generate a relational expression that can characterize a non-delta transgression slope and a river length; and determining the continental shelf profile of the target work area according to the relational expression. According to the continental shelf profile determining method and apparatus based on non-delta transgression provided by the present invention, the effects of river sediment supply and sea level rise on the continental shelf profile are comprehensively considered in a scenario of non-delta transgression, and thus, changes in the continental shelf profile of the target work area in historical periods are determined more accurately.
