Three-dimensional geological modeling method and device

Abstract

The invention discloses a three-dimensional geological modeling method and device, relates to the field of geological modeling, overcomes primary shortcomings of an existing integral approach, combines advantages of a local method and can quickly establish a multilayer complex geological body through the utilization of geological original data. The three-dimensional geological modeling method mainly comprises obtaining fault control data from collected geological data, utilizing a stratum inversion method to fit a fault surface, setting fault lofting parameters for the fault surface, and establishing a planar three-dimensional fault; utilizing the stratum inversion method to establish three-dimensional geological body blocks containing different strata, and performing overall surface fitting operation on the post-inversion three-dimensional geological body blocks to obtain a three-dimensional geological body; performing stratum forward modeling on the established three-dimensional geological body by utilizing the fault control data and the planar three-dimensional fault and dividing the three-dimensional geological body into different three-dimensional geological body blocks; assembling the divided three-dimensional geological body blocks to form an integrated fault-contained three-dimensional geological body. The three-dimensional geological modeling method and device is mainly applicable to three-dimensional modeling of fault display.

Description

technical field [0001] The invention relates to the field of geological modeling, in particular to a three-dimensional geological modeling method and device. Background technique [0002] At present, the 3D representation and simulation technology of faults at home and abroad is still in the research and exploration stage. The mainstream fault modeling can be divided into two categories: the fault modeling method based on geological origin, also known as the whole method; the fault modeling method based on partition interpolation. Modular method, also known as local method. [0003] The integral method requires an in-depth investigation and understanding of the geological site, detailed and accurate geological data, including topographic maps, plane section geological maps, drilling information, etc., and requires users to have high professional knowledge of geological background, so this method It is a relatively complex and professional modeling method, which is mainly su...

AI Technical Summary

Problems solved by technology

The disadvantage is that it is not suitable for modeling complex shapes and faults generated by multiple tectonic movements, and requires more mathematical geological expertise

The disadvantage is that more detailed geological data that can limit each block are required, preferably including topographic maps, plane section geological maps, drilling information, etc., the efficiency of modeling is low, and the workload of model modification and editing is large
