Abstract

The invention provides a palaeogeomorphic restoration method and apparatus. The method comprises the steps of establishing a sequence isochronous stratigraphic framework of a target stratum; determining an overlying stratum marker surface of the target stratum in the sequence isochronous stratigraphic framework; based on the position of the overlying stratum marker surface, determining an underlying stratum reference surface in the target stratum; according to a first thickness value between the overlying stratum marker surface and the underlying stratum reference surface as well as a pre-obtained second thickness value between the overlying stratum marker surface and a palaeogeomorphic unconformity surface, determining a palaeogeomorphic value; and based on the palaeogeomorphic value and a palaeogeomorphic value obtained previously according to earthquake data of the target stratum, restoring a paleogeomorphy of an unconformity surface of a weathered crust of the target stratum. According to the palaeogeomorphic restoration method and apparatus provided by embodiments of the invention, the defects in palaeogeomorphic restoration in the prior art can be solved, so that the palaeogeomorphic restoration precision is improved.

Description

technical field [0001] This application relates to the technical field of exploration and development of oil and gas fields, in particular to a method and device for restoring paleogeomorphology. Background technique [0002] The study of paleogeomorphology started in the 1950s and is currently being applied in a wide range of disciplines. my country started relatively late in searching for oil and gas through the study of paleogeomorphology. It was not until the 1970s that we began to really pay attention to the study of structural geomorphology. Discovery of large gas fields, research on the western slope of the Bozhong Sag in the continental rift basin, research on ancient buried hills in the Zhanhua Sag and Gubei Sag in the faulted basin, etc. [0003] At present, Li Daosui uses the compensation thickness impression method and the residual thickness method to restore paleogeomorphology, focusing on the analysis of the control of paleogeomorphology and trench factors on t...
