水平井井轨迹三维可视化技术研究

Research on Three-dimensional Visualization of Horizontal Well Trajectory

针对水平井解释评价过程中需确定水平井轨迹与油藏之间几何关系的问题,结合三维可视化技术提出了一种三维属性模型的构建方法,将井轨迹构建成三维可视化模型。该方法将井轨迹及剖面数据表征为三维可视图,更加直观、形象地展示了水平井井轨迹在地层中的穿梭和走向,结果表明,该方法有效提升了水平井的解释评价。

In order to solve the problem in determining the geometric relationship between horizontal well trajectory and reservoir in the process of horizontal well interpretation and evaluation,this paper proposes a method to build a 3D attribute model based on 3D visualization technology.The well trajectory is constructed to be a 3D visualization model.In this method,the well trajectory and profile data are represented as three-dimensional visual map,which more intuitively and vividly shows the shuttle and trend of horizontal well trajectory in the formation.The results show that this method effectively improves the expound and assess of horizontal well.
