Development And Achievement Of Three-dimensional Visualization In Digital Oilfield Based On Skyline

Three-dimensional Geographic Information System (3DGIS) ,which is one of the effect solutions of Digital Earth, has improved its theory and technology. As one of the aims of the Digital Oilfield is the realization of the integration of the ground-underground, is in an urgent need to a set of mature theories, practical data models to support and to achieve their specific business applications. 3DGIS, with the ability of massive, multi-source, integration of heterogeneous data and intuitive of three-dimensional visualization , is very suitable for the solution of ground-based three-dimensional visualization in the Digital Oilfield. Through research analysis, the United States TerraSuite series of Skyline's products is good for the realization of 3DGIS, due to its flexible architecture, interface open, the secondary development of features is convenient. So this paper argues that this method is a suitable platform to realize the three-dimensional visualization in oil field.In this paper gives a specific solutions to constructing a 3D oil field which based the technology of Skyline and according to the characteristics of oil field. Such as the wide spread of oil field features, a wide range of diverse sources of business data, such a mass geographic data etc. By studying the theory of technology and the support systems of Skyline, the author fully exploit the actual demand in oil industry and developed the business logic modules in the application level. Finally, achieved the goal of a 3D oil field.The main work in this article includes:(1) Architecture Design: As the characteristics of distributed applications in oil industry, the system used the means of local and network data storage to reduce the requirements of the local computer hardware; Multi-database technology to solute the relationship of static data and dynamic landmark data; Using the stream mode by loading vector data greatly reduces the one-time consumption of system resources and improve the user's experience. Through the methods of project standard organization, successfully solve the problem of dislocation after packing, and then achieve the development teamwork;(2) Business Module Development: According to the demand in 3D oil field, the system developed three major categories of business modules, such as dynamic three-dimensional design wells module; The integration of geography and geology information module; Analysis of contingency plans for the command module.(3) Achievement of 3D model: On 3D model performance, the system achieves the RS-SU-TE process and improves the efficiency of the system modeling; by using the technology of modify the properties of the construction features, multi-level texture mapping and multi-layered detail (LOD) techniques to achieve optimization of the model. In this way can effectively meet the needs of the mass model and to ensure the demand of system efficiency and stability.This article which is based Skyline technology set up a 3D oil field platform successfully, achieve the fusion of geographic information and multi-source data, provide the functions of roaming and analysis in a 3D oil field. And develop suitable module for the actual demand in oil field. The results of this paper can effectively improve the oil field exploration, development and management of the technical level and the actual results.
