【摘要】：在不同结构的采油井环境下绘制三维井眼轨迹和井眼轨迹中井筒管柱的静态组合是虚拟现实领域中的一个重要问题。怎样利用本课题将井下作业管柱的组成、井眼轨迹的显示在一个虚拟的场景中以一个三维可视化的平台展现在工作人员面前,加深工程作业人员对运动力学模型以及防偏磨方案的理解。进行此方面的课题研究,具有广泛的应用前景和很高的实际应用价值。本文分析和研究了井眼轨迹的绘制算法,并在此基础上进一步研究了井筒的三维显示技术。在分析对比各种测斜算法后,选取符合实际需求的测斜计算模型,同时将预测井眼轨迹进行绘制,按照已经绘制成型的井号类型进行适应油田生产需求的井下作业管柱的模拟生成,整个过程以三维可视化的方式呈现。本文提出了一种对于井眼轨迹的新绘制方法,利用VSL语言实现点、线、面的绘制,将井眼轨迹曲线筒状化,并为其设计人机交互功能,增强系统的趣味性。通过对三维模型的读取、中心轴的设定、模型定位与碰撞检测技术,完成井下作业管柱的生成与对井筒的交互操作。本课题旨在建立采油虚拟现实实验平台,该平台采用三维可视化技术,将钻井、井下等多种业务基础数据和业务知识综合起来建立井筒三维可视化模型,进行井下作业管柱三维静态仿真,用于井下作业指导与管理,有助于井下作业人员相互交流与协作,还可以进行井眼轨迹的显示,井下管柱各生命周期的模拟。通过三维井眼轨迹的实时动态绘制与井下工艺管柱的自由组装,实现整个井下开采过程的三维展示,让用户沉浸在这个虚拟的环境里,并了解和掌握井下作业的具体生成流程,制订一系列科学生产的原则和规范,为工程人员提供强大的辅助决策支持方面具有重大意义。
[Abstract]:It is an important problem in the field of virtual reality to draw the static combination of the borehole string in the 3D well trajectory and the wellbore trajectory in the environment of different structures. How to make use of this subject to make up the downhole working string is an important problem in the field of virtual reality. The well trajectory is displayed in a virtual scene with a three-dimensional visual platform, which deepens the understanding of the motion mechanics model and the anti-bias wear scheme of the engineering workers. This paper analyzes and studies the algorithm of hole trajectory drawing, and further studies the 3D display technology of wellbore. The slanting calculation model is selected to meet the actual demand. At the same time, the predicted well trajectory is drawn, and the downhole working string is simulated according to the type of well number that has been drawn to meet the production demand of oil field. The whole process is presented as 3D visualization. In this paper, a new drawing method for borehole trajectory is proposed. The drawing of points, lines and surfaces is realized by VSL language, and the borehole trajectory curve is cylindrical, and the human-computer interactive function is designed for it. Enhance the interest of the system. By reading the 3D model, setting the center axis, locating the model and collision detection technology, The purpose of this project is to establish a virtual reality experimental platform for oil production. The basic data and knowledge of underground operation can be integrated to establish a three-dimensional visualization model of borehole and carry out three-dimensional static simulation of downhole operation string, which can be used to guide and manage downhole operation, which is helpful for the communication and cooperation of downhole operators. It can also display borehole trajectory, simulate the life cycle of downhole string, and realize the 3D display of the whole downhole mining process through the real-time dynamic drawing of 3D borehole trajectory and the free assembly of downhole technological string. It is of great significance for users to immerse themselves in this virtual environment, to understand and master the concrete generating process of downhole operations, to formulate a series of principles and norms for scientific production, and to provide strong auxiliary decision support for engineers.
