三维井眼轨迹仿真研究

Research on Simulation for 3-D Well Trajectory

对井眼轨迹三维仿真,能使井眼轨迹更加生动直观的展示出来,给钻采作业提供可靠依据。在曲线插值算法和图形透视原理研究的基础上,将离散的井眼轨迹数据通过插值算法平滑化,并通过三维透视投影原理实现其三维仿真。在理论研究的基础上,利用Visual Basic开发了三维井眼轨迹仿真系统,该系统可进行三维井眼轨迹放大、缩小、旋转等操作,可从多方位和多角度观察仿真结果。系统使用维护方便,具有较强的实用价值。

Well trajectory can be showed vividly and intuitionally by the three - dimensional simulation of well trajectory. 3 - D simulation provides dependable basis for drilling and production. Based on the curvilinear interpolation algorithm and the study of graphics perspective theory, the discrete well trajectory data are smoothed through interpolation algorithm and its 3D -simulation is performed by 3D -perspective projection principle. On the basis of the theory study, using Visual Basic develops the 3D -well trajectory simulation system. The system can magni- fy, shrink, rotate the 3D -well trajectory and observe the result from all around and different point of view. This system can be used and maintained easily, with powerful application value.
