Background
The geological model provides guidance for mineral resource exploration and exploitation, is the basis of a resource model and a grade control model, and has different importance. The concept of three-dimensional geologic modeling (3D Geological Modeling) was first proposed by Canadian scholars Simon W.Houlding in 1993. Three-dimensional geologic modeling is a technology for combining tools such as spatial information management, geologic interpretation, spatial analysis and prediction, geostatistics, physical content analysis, graphic visualization and the like in a three-dimensional environment by using computer technology, and is used for geologic analysis. The SEG/EARG three-dimensional modeling Committee was established as early as 1992 by International Association of exploration geophysicists and European Association of exploration geophysicists, and held geologic computer conferences in Leeds, new Zealand Otago, bristot, va.U.S. including geologic modeling, simulation and visualization. Developed countries have studied earlier in terms of geologic modeling and visualization. Three-dimensional representations of geochemical information and some geochemical three-dimensional models were proposed as early as Bak, smith, and Raper, et al in 1989. The research result of a presenter Simon W.Houlding of the three-dimensional geologic model concept fully reflects the following three-dimensional geomodeling: computer technology for geologic characterization (Geosience Modeling, computer techniques For Geological Characterization).
Geologic models are created for specific purposes, and a clear knowledge of the purpose of modeling is critical before geologic interpretation and model creation can take place. The development and research of carbonate fracture-cavity oil reservoirs are continuously in progress, and the northwest oilfield division creatively proposes the concept of a 'broken solution oil reservoir'. Through high-precision three-dimensional seismic data, the development range of the broken solution oil reservoir is finely delineated, through a multi-attribute seismic fusion technology, the deep research on the internal structure and the separation of the broken solution oil reservoir is increased, and a method capable of accurately establishing a regular karst cave sphere model is needed at present so as to provide technical support for more accurately recognizing and developing the broken solution oil reservoir.
