【摘要】 近年来,基于虚拟现实技术的三维模拟仿真,引起了人民的广泛关注。此技术打破了传统模式的局限性,越来越多的人和企业意识到了虚拟三维模拟仿真的重要性。虚拟三维可视化模拟仿真既有理论研究的价值,又有广泛的应用基础和巨大的市场。论文首先在科学可视化技术和虚拟现实技术研究的基础上,对OpenGL(Open Graphics Library)的体系结构进行了深入探讨。OpenGL是近年发展起来的一个性能卓越的图形应用编程接口,它已经成为三维图形设计的工业标准。论文对Windows环境下使用C++ Builder以及OpenGL实现三维可视化的方法进行了研究,并基于C++ Builder和OpenGL开发了钻井井场虚拟培训系统。该系统动态地模拟了钻井过程中正常钻进、起下钻、接去单根等操作,实现了钻井过程的实时三维模拟仿真。此外,由于实际钻井设备复杂,不易进行物理仿真,因此论文还对钻井设备的3D建模与合成方法进行了研究。结合3DS MAX软件和OpenGL,设计并制作了复杂钻井设备的模型,极大地增强了钻井及井控模拟仿真系统功能,该技术对于其它可视化仿真系统的三维物体建模和显示具有良好的借鉴作用。本系统得到了很好的应用,使得员工在岗前既能进行知识学习又能进行技能培训,不仅降低了传统培训直接操作的危险,也降低了不必要的经济损失,收到了良好的效果。
【Abstract】 Three-dimensional analog simulation based on virtual reality technology is widely studied in recent years. More and more people and enterprises begin to realize the importance of virtual training, which does not have the limitations that traditional method has and the needs has a trends of growing. The study of virtual three-dimensional analog simulation technology has not only a great theoretical value, but also a grand foundation of application and huge potential market.In this thesis, first, the systematic structure of OpenGL (Open Graphics Library) is deeply discussed on the basis of scientific visualization and virtual reality. OpenGL is a newly developed excellent graphics application programming interface (API), and it has become the industrial standard of 3D graphic design. Then, the 3D visualization realizing methods using C++ Builder and OpenGL under Windows environment are studied and some dynamic displays and control of operations during the virtual training system of drilling, such as normal drilling, tripping, adding and removing stands, etc., are realized.In addition, 3D object modeling and synthesizing are also studied in this thesis due to the complexity of the drilling equipments. 3DS MAX and OpenGL are combined together to make the drilling equipment models. Therefore, the function of the drilling and well-control simulation system is enhanced. The proposed method will be benefit to other visualization system.The training system is well applied and the training effect is favorable. The trainee not only obtains knowledge but also gets skills. By the application of virtual training system, the dangerousness in traditional training is avoided, and the unnecessary economic loss is lowered.
