Construction method of three-dimensional geologic model

Abstract

The invention relates to a three-dimensional modeling technology and discloses a construction method of a three-dimensional geologic model. The construction method solves the problem that massive auxiliary two-dimensional analysis must be carried out when the three-dimensional geologic model is built traditionally, so that during the modeling process, the workload is large, a modeling process is complex and the model cannot be automatically updated. According to the construction method, direct three-dimensional interpretation analysis of geological information is achieved in a dynamically and controllably adjusted surface fitting (interpolation) mode, and two-dimensional analysis results are no longer essential bases; an engineering geological base information database closely combined with production practice is established, and collecting work of geological base information and information storage management are carried out on the basis of three-dimensional analysis interpretation; the base information is continuously enriched and perfected along with a production schedule and can be rapidly reflected to the analysis and adjusting process of the three-dimensional geologic model; and three-dimensional direct output or two-dimensional sectioning output of geologic results is correlated with the engineering geological database, and normalized automatic output is formed. The construction method is suitable for three-dimensional modeling for geology.

Description

technical field [0001] The invention relates to three-dimensional modeling technology, in particular to a method for constructing a three-dimensional geological model. Background technique [0002] Obtaining accurate geological conditions of the project area is an indispensable basic link in the design of water conservancy and hydropower. However, the geological body is buried underground and is unknown before it is fully excavated; on the other hand, the geological body is naturally formed in the long process of geological history development, which is the transformation of specific original construction and later geological processes The comprehensive product of superimposition is extremely complex, and its complexity is mainly manifested in: the spatial distribution of various geological units is uneven, the change of geometric spatial form is different, and the intersecting of different units in space is unique. A certain amount of randomness and so on. The only way fo...
