Solution Overview
Problem
Designing geological simulation grids is a time-consuming and often inaccurate process due to the complexity of geological environments and the need for precise representation of geological structures, with existing methods requiring significant re-design of grids to conform to geological surfaces.
Innovation Solution
A computer-implemented method that allows for the simple and accurate design of geological simulation grids by identifying and transferring parameters to geometrical structures corresponding to geological surfaces, without requiring the grid to conform to the surface, enabling late-addition of information and handling irregular or unstructured geometries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the geometrical grid is designed to conform to geological surfaces, then the simulation accuracy is improved, but the design time and complexity increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-identifying which geometrical structures of the grid correspond to geological surfaces before parameter transfer. This pre-processing step establishes a mapping relationship in advance, avoiding time-consuming adjustments during the simulation setup phase while maintaining accuracy.
Solution Approach 2:
The patent extracts the essential correspondence relationship between grid structures and geological surfaces, separating this identification task from the overall grid design process. By extracting and handling this mapping independently, the method reduces the complexity of the main grid design workflow while preserving simulation accuracy.
2Manufacturing precision
If the geometrical grid is redesigned to conform to geological surfaces, then the spatial discrepancy is reduced, but the device complexity and computational cost increase
Solution Approach 1:
The patent creates a virtual correspondence mapping between geometrical structures and geological surfaces without physically redesigning the grid. This copying approach transfers the essential spatial relationship information to guide parameter assignment, achieving spatial accuracy without the complexity of grid reconfiguration.
Solution Approach 2:
The patent introduces an intermediary mapping layer that connects geometrical structures to geological surfaces. This intermediary correspondence relationship serves as a mediator that transfers parameters accurately without requiring direct conformity between grid geometry and surface geometry, thus reducing design complexity.
3Reliability
If existing grid structures are modified to conform to geological surfaces, then the representation accuracy is improved, but the loss of time for re-design increases
Solution Approach 1:
The patent applies local quality by identifying and treating only those specific geometrical structures that correspond to geological surfaces, rather than redesigning the entire grid. This localized approach transfers parameters with high accuracy to relevant structures while leaving the rest of the grid unchanged, thus minimizing re-design time.
Solution Approach 2:
The patent performs preliminary identification of correspondence relationships between geometrical structures and geological surfaces before parameter transfer. This advance preparation enables targeted parameter assignment without time-consuming trial-and-error redesign, improving representation accuracy efficiently.

AI summary
The invention notably relates to a computer-implemented method for designing a geological simulation grid, the method comprising: providing a geometrical grid that conforms to a set of geological structures of a geological environment; providing a geometrical surface that represents a geological surface of the geological environment, the geological surface being outside the set of geological structures; identifying geometrical structures of the geometrical grid that each correspond to a respective location of the geometrical surface; and transferring to each identified geometrical structure one or more respective parameters, each parameter being a value of a respective property of the geological surface. This improves the field of geological simulation.
