【摘要】 针对日益复杂的井下油气钻井作业，为满足井眼轨迹的可视化的控制决策需求，系统通过3Ds max设计井场环境、地层和钻头模型，在unity3d引擎下编写C#(C sharp)脚本程序，驱动钻头在虚拟环境下运行并绘制井眼轨迹，从而研发的一套定向井井眼轨迹虚拟可视化系统。以陕北某定向井为例，在可视化地层中，实现了优化井迹与随钻井迹的三维动态显示。结果证明，上述系统实现的钻井平台虚拟可视化、虚拟钻头动态控制和沉浸式动态漫游显示，不仅为随钻井眼轨迹精确控制与决策提供提供一个友好的临境式、交互式决策环境和研究平台，同时降低钻井成本和风险，提高研究效率。更多还原

【Abstract】 Aiming at the increasingly complex downhole oil and gas drilling operations, the system, in order to meet the requirements of visual control and decision-making of the formation wellbore trajectory, uses 3 Ds max to design the well site environment, formation and bit model, and writes C#(C sharp) script programs which can drive the drill bit to run and draw the well trajectory under the unity3 d engine, thus developing a set of virtual visualization system for directional well trajectory. Taking a directional well in northern Shaanxi as an example, the three-dimensional dynamic display of optimized well traces and drilling traces is realized in the visualized formation. The results prove that the virtual reality(VR) system which includes the drilling platform, the dynamic control of the virtual drill bit and the immersive dynamic roaming display can provide not only a friendly and interactive decision-making environment but also the precise control and decision-making of the drilling trajectory researching platform. At the same time, it can reduce drilling costs, and risks and improves research efficiency.更多还原
