Virtual Manufacturing Technology Is Applied Research In The Simulation Of Underground Work

Recently, The Virtual Manufacture becomes one of researching hot spot both in the scientific and technological circles and enterprises. This paper introduces the conception, feature and classification of the Virtual Manufacturing, and expounds the research significance and content of this study according to the internal and external present conditions.This paper discuss the key technologies of Virtual Manufacture, including the method and theory of the displaying of the 3D scene, polygonal mesh model, visual light model, collision checking, 3D geometry transform and the particle system.This paper introduces two great development software which are MultiGen and OpenGVS and depicts the software performance, module function and so on. It has provided a strong foundation for the future development.The downhole operation simulation system is realized, which based on the desktop operating system using the software performance of MultiGen and OpenGVS. The real-time controlling and the verisimilitude 3D modeling are both considered sufficiently, and the fashionable 2D and 3D technologies and object oriented software technology are used in its design. This simulation system is including the simulation of production tools and proceeding, which is suitable both in the improvement of production proceeding for the engineer and in the worker training. The paper discusses the designing proceed, theory and details of this simulation system, including the brief introduce of simulation system, the design of interaction graphic user interface, the 3D modeling of oil well ground facilities and downhole tools, the design of 3D engine for downhole operation simulation system, and explains the using of 3D animation in this system with a real example, and finally sums up the general regular pattern of simulation system designing.It's a new experiment that utilizing of the Virtual Manufacturing in the petroleum industry, and it's also an infallible tendency of the technology innovation in the petroleum industry.
