摘要
OpenGL是一种三维图形开发标准 ,是从事三维图形开发工作的必要工具 ,其稳定性、可靠性、可扩展性等特点 ,赋予了其强大的生命力和应用前景 ,OpenGL已经广泛应用于在CAD/CAM /CAE、医学图像处理、虚拟现实、娱乐、广告等领域。OpenGL同样可以应用于油藏开发这类特殊的三维问题表示 ,油藏本身是一种时空系统 ,通过油藏动态监测数据的分析和地质统计学方法的应用 ,实现油藏的动静态描述 ;利用OpenGL技术 ,能够将地下油藏的内部状态形象直观地呈现给油田管理层和技术人员 ,显著提高工作效率。阐述了OpenGL的基本概念、特点、原理、工作流程及其绘制流程 ,基于OpenGL技术开发油气藏构造三维可视化工具 ,嵌入到油气藏开发管理GIS系统中 ,扩展了目前GIS系统欠缺的三维空间描述能力。
OpenGL is a kind of development criterion of 3D graphics and a necessary toolkit for development of 3D graphics. Its stability, reliability, and expansibility make it unbelievably powerful and widely applicable. OpenGL has been widely applied in many fields such as Computer Aided Design (CAD), Computer Aided Manufacturing (CAM), Computer Aided Education (CAE), medical image manipulation, virtualreality, entertainment, and advertisement business. OpenGL can also be applied in presentation of some special three dimension problem, such as reservoir exploitation. Reservoir is a complicated spatio temporal system. Reservoir dynamic and static characterization would be achieved through analysis of dynamic monitoring data and employment of geostatistics method. By means of OpenGL, the interior state of underground oil field will be presented visually and vividly to the administrative levels of oil field and engineers. As a result, the work efficiency will be improved evidently. This paper introduces the basic conception, characteristic, principle, working flow and drawing flow of OpenGL. The three dimension visual toolkit of reservoir construction based on OpenGL techniques is inset in the oil field management system of geographic information system (GIS). It will enhance its inadequate description ability for three dimensional space in current GIS system.
