Three-Dimensional Dynamic Simulation of Drilling Engineering Based on Unity 3D

以石油钻井井场为原型,对井场的设备布局、结构、运动过程等进行剖析,实现对石油钻井井场设备的动态仿真。通过3D max软件建立了井场的三维模型、优化模型并且搭建出整个井场的虚拟场景,将建立好的模型导入Unity 3D软件中,并且利用Unity 3D软件建立沙漠地形、天空、树木等虚拟场景的必需元素。借助软件自带的脚本编程功能和物理引擎对石油井场的设备运动进行动态仿真和交互设计,实现了对虚拟场景中的设备模型平移、后退、旋转等运动控制,完成了石油钻井八大作业系统。起升钻柱实验结果证明,所设计的钻井工程三维动态仿真系统具有良好的三维性、交互性和逼真性,为建立石油钻井虚拟仿真培训平台奠定了基础。

Taking the oil drilling well site as a protolype, the equipment layout, structure and movement process of the well site are analyzed, and the dynamic simulation of the well site equipment is realized. The three-dimensional model and optimization model of the well site were established by using 3 D max software, meanwhile the virtual scene of the wholewell site was set up. The established model is imported to Unity 3 D software, and the essential elements in the virtual scene,including desert terrain, sky and trees, are established u- sing the Unity 3D software. To use scripting capabilities and physics engines in Unity 3D software realizes the dynamic simulation and interaction design of well site equipment movement, the translation, backward, and rotating movement control of equipment models in the virtual scene and the eight operation systems of petroleum drilling engineering. The experimental results of lifting drill string＂ show that the 3D dynamic simulation system designed for drilling engineering has a good three-dimensionality, interactivity and vividness, which lays the foundation for the establishment of oil drilling virtual simulation training platform.
