Embodiment Construction

[0033] This example introduces in detail a sequence analysis method for 3D mesh generation. In the present invention, a different idea from the traditional automatic event tracking is adopted, and the information carried by the automatic event tracking results is used instead. Starting from the overall situation, the spatial topology information of the tracking results is recovered by performing layer sequence analysis on the patch set, and using This information classifies the results for use in geological modeling.

[0034] In the present invention, the input data is the result set generated by automatic event tracking. The automatic tracking of the event axis can be regarded as given some seed points, according to the characteristics of the seed points, searching for adjacent sampling points with similar properties in the three-dimensional space, and continuously expanding the process of the connected domain, the result is a patch composed of sampling points (3D) or line s...

Abstract

The invention discloses a hierarchical sequence analysis method oriented to the generation of three-dimensional hierarchical grids, which is used for geologic stratum modeling and underground structure analysis, and is characterized by comprising the following steps of: scanning surface patches consisting of discrete points; establishing a target function according to the scanned result; solving the solution of the target function in case of a minimum value, and considering the solution as a sequence value of the surface patches; and classifying the surface patches by using the sequence value, and considering classified surface patches as data of the generation of the hierarchical grids. When the method disclosed by the invention is adopted, the automatic classification of automatic tracking results of axes in the same direction can be realized, and therefore, automatic explanation can be completed, and heavy manual classification and pickup can be eliminated; moreover, efficiency of the explanation process from a seismic data body to a hierarchical grid modeling is effectively improved.

Description

technical field [0001] The invention relates to the automatic interpretation of seismic data using the results of event tracking, and the use of the interpreted results for three-dimensional layer grid generation. The interpretation method is based on sequence analysis. Background technique [0002] Petroleum resources are the main form of energy that the world economy relies on today, and also provide raw materials for many chemical industries. It can be said that oil is the lifeblood of a country's economic development. As the only way to obtain oil resources from the ground, oil and gas exploration plays a fundamental role in the entire oil industry. Due to the complex geological conditions and the scarcity of oil resources in our country, oil and gas exploration in our country is facing a more difficult and arduous situation. [0003] Modern oil and gas exploration is generally divided into the following links: geological survey, field geophysical exploration operatio...
