A Fusion Geological Structure Modeling Method Based on Semantic Description

Abstract

The invention discloses a fusion geological structure modeling method based on semantic description. In order to solve the problem of lack of geological meaning in the traditional three-dimensional geological structure modeling process, the invention proposes a semantic description of the structure model, which is obtained by geological workers according to the interpretation data A preliminary semantic description, interpreting the data as the basic semantics as a constraint to generate a preliminary structural model; then proposes an extraction algorithm for the semantic network of the corresponding structural model, and with the assistance of the preliminary model, the semantics are edited by geologists to extract more Meticulous semantic description, the extracted semantic description constrains the structural topology of the model in the next traversal; through cyclic traversal until the complete structural framework model is obtained; finally, a fusion geological structure modeling method based on semantic description is proposed, according to the complete structural framework model Restructure the surface.

Description

technical field [0001] The invention belongs to the field of geological structure meeting, in particular to a three-dimensional geological structure modeling technology. Background technique [0002] Under the action of the earth's internal and external stresses, rock formations will deform or displace, thus forming complex geological structures such as faults and folds. The modeling of complex geological structures plays a vital role in the exploration of underground resources. Studying the method of 3D geological modeling and establishing a 3D geological model that can reflect the geological situation can not only meet the actual engineering needs, but also solve the application field problems such as oil and gas exploration and development, and can also promote the development of geosciences. [0003] Three-dimensional geological structure modeling is divided into three main steps: geological surface reconstruction, geological surface topological relationship analysis and...
