摘　　要：虚拟现实(系统)已广泛应用于地震资料的交互解释、储层模型建立、钻井轨迹设计以及海上平台设计等领域。为此,尝试将其应用到导向钻井领域中来解决导向钻井中地层、井眼轨迹、靶点、设计轨道以及实钻轨迹等钻井对象的三维可视化问题,以期提高钻井人员对地层构造及储层特性的判断力、钻头在储层内轨迹的控制能力等,进而提高钻井成功率。为此,详细阐述了钻井对象的虚拟现实建模方法及其三维可视化的实现技术,并给出了一个三维可视化的示例。Virtual reality (VR) has been already widely used in interpretation of seismic data, reservoir modeling, drilling trajectory design, platform design and so on. Attempts have been made to apply VR to steering drilling to realize 3D visualization of stratum, old well trajectories, targets, designed trajectories, and actually drilled trajectories, etc. It will effectively enhance the abilities of the drilling personnel to judge formation structures and reservoir characteristics, and the ability to effectively control the bit path through the reservoir, so as to largely improve the drilling success ratio. The virtual reality modeling method and the implementation technology of 3-D visualization of the drilling objects are described in detail in this paper, and a visualization example for a 3-D object is given.
