Because the drilling simulation system based on 3D animation and OpenGL technology has not strong immersion and good interaction, a drilling simulation system based on virtual reality technology was developed. The model calculation software was designed on the basis of mathematical modeling to process of drilling, which can realistically reflect the changes of parameters in drilling field. Dynamic drilling virtual scene was realized by constructing a complex drilling equipment model with 3D MAX software and using behavior block control independent movement of each model in Virtools platform. In the hardware platform coordination, this scene can simulate all kinds of drilling operation process vividly, such as drilling, tripping, making a connection, screwing on, screwing off and so on. The realization of the system provides a new way for the training of oil-fixed safety task operation, has certain value to spread.%针对基于三维动画和OpenGL技术的钻井仿真系统存在画面沉浸感不强、交互性差等不足,开发了基于虚拟现实技术钻井仿真系统.在对钻井过程进行数学建模的基础上,设计了模型计算软件,该软件逼真地再现了钻井现场参数的变化情况.利用3D MAX建模软件构建了复杂的钻井设备模型,并在Virtools平台下利用行为模块控制各模型独立的运动,实现了动态的钻井虚拟场景.该场景在硬件平台的配合下,能够逼真地再现钻进、起下钻、接单根、上扣、卸扣等几十种钻井工艺流程.该系统的实现为油田安全作业的培训提供了一条新的途径,具有一定推广价值.
