Three-dimensional Geological Modeling And Integrated Demonstration System Based On Multi-dimensional Geo-information

The Multi-dimensional Geo-information is obtained through different exploration, it can help us to understand the different attributes of geological information. It usually includes geophysical data, geological survey data and drilling data and so on. With the deepening of field exploration, We will get more and more Multi-dimensional Geo-information. Currently, there is no effective modeling method for Multi-dimensional Geo-information. Therefore, the visualization of Multi-dimensional Geo-information has theoretical and practical significance of researching geological, geophysical prospecting, drilling and other areas. Therefore, we must carry out research work in this direction.This paper was supported by sub-project of Deep Exploration in China Program(Sinoprobe) “Comprehensive geological model and Three-demensional Display of Field experiments and Demonstration Base(201311197-2)”, and We research the geological modeling and visualization system in China. At present these system are mostly used either drilling data or single kind of geophysical data. The demonstration of these system is mostly single three-dimensional geological model. In view of the above problems, We design a system, called it Three-dimensional Geological Modeling and Integrated Demonstration System Based on Multi-dimensional Geo-information. This paper mainly carry out research work from the following aspects:First of all, we should get the reliable source of geological modeling data. The source of geological modeling is from drilling data,geophysical data and other geo-information. We can extract data which is related with three-dimensional geological modeling. In the extraction process we proposed the threshold Multilevel Median Filter in seismic data detection for vibroseis which was used for the vibroseis in Geophysical.Secondly, aiming at the single problem of the data source which uesd in conventional three-dimensional geological modeling. Then the method of three-dimension geological modeling based on multi-dimensional geo-information was proposed. Combined with the geological characteristics of the study area, we use TIN model and TP model to build the three-dimension geological model.Again, aiming at the problem that the conventional visualization system is a signle three-dimensional geological model in the content of demonstration. The the method of integrated demonstration based on multi-dimensional geo-information is proposed.At last, We use VTK(Visualization Tollkit) to complete the development of this system. The system is verified by the multi-dimensional geo-information of Xingcheng demonstration and experimental base. We use the system to build a three-dimensional geological model. It realized the integrated demonstration of three-dimensional geological model and multi-dimensional geo-information. It demonstrates the effectiveness of the system. It proxides us more intutive understanding of three-dimension geological model and multi-dimensional geo-information. It is working for the geological interpretation of convenience. It enriches the content demonstration of geo-information visualization. It also provides a strong platform for geological interpretation and resources exploration. It makes full use of the value of existing multi-dimension geo-information.
