A Representation Method for Constructing Continental Sequence Stratigraphic Framework Based on Multidimensional Data

Abstract

The invention provides a continental-sequence stratigraphic framework construction representation method based on multidimensional data. The method comprises the following steps of carrying out data collection and analysis; according to a lithology mutation surface, a curve change surface and other characteristics, establishing a sequence stratigraphic framework on ''points''; according to truncation, onlap, downlap and other interface characteristics, establishing a sequence stratigraphic framework on 'lines''; based on the sequence stratigraphic framework of the lines, according to data correlation of the lines, connecting the lines so as to form a surface, drawing a sequence stratigraphic thickness association map, and analyzing a distribution characteristic on sequence stratigraphic ''surfaces''; based on a characteristic on the ''surfaces'', establishing a whole-basin sequence-stratigraphic three-dimensional space ''body'' and improving sequence stratigraphic framework construction; according to a construction scheme of a sequence stratigraphic framework 'body'', collecting sequence developmental time series data; and analyzing a developmental characteristic of a basin sequence in different developmental periods in a three-dimensional space and a vertical evolution characteristic, establishing a sequence stratigraphic framework at a whole basin ''period'', and finally establishing a whole basin sequence stratigraphic framework.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a characterization method for constructing a continental sequence stratigraphic framework based on multidimensional data. Background technique [0002] After decades of development, sequence stratigraphy has become the most important basic work and method for finding energy resources, especially in continental lakes in my country. Great success has been achieved in the oil and gas exploration of the Basin, which has also led to differences in theoretical systems and technical routes, resulting in vastly different research results for the same set of strata in the same research area, which seriously restricts oil and gas exploration. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a method for constructing and characterization of continental sequence stratigraphic framework based on multi-dimensional data.

[0002] After decades of development, sequence stratigraphy has become the most important basic work and method for finding energy resources, especially in continental lakes in my country. Great success has been achieved in the oil and gas exploration of the Basin Basin, which has also led to differences in theoretical systems and technical routes. As a result, the research results of the same set of strata in the same research area vary widely, which seriously restricts oil and gas exploration.
