导向钻井信息三维可视化系统的实现

Three-dimensional visualization of steering drilling information

研究了虚拟现实系统中三维对象虚拟现实建模、立体显示及人机交互等实现技术,并将其运用于导向钻井信息三维可视化系统的实现中,解决了导向钻井中地层、井眼轨迹、靶点以及设计轨道等钻井对象的三维可视化问题.系统为钻井人员提供了一个钻井信息高度可视化的工作环境,能够有效地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等,从而提高钻井成功率.详细描述了钻井对象的虚拟现实建模方法及其三维可视化实现,并给出了一个三维对象可视化的示例.

The modeling,display and human-machine interaction in the visualization of a 3-D object are discussed thoroughly,and they are applied to the threedimensional visualization of steering drilling information.Thus,the 3D visualization of the formation,real well track,target point and designed well track in steering drilling can be implemented.A case is presented.By the visualization of drilling information,drilling workers can clearly understand the structure of formation and the characteristics of reservoir,increase the control ability of drilling bit and thus can improve drilling success rate.
