Development of Wellbore Trajectory Prediction and 3D Visualization System of Borehole Trajectory

对钻井施工过程中的问题进行了调查,并对钻井井底盲区测量问题及对现行的井眼轨迹三维可视化系统进行了研究。对井眼轨迹测点方位计算问题,选取了符合我国国情的石油钻井圆柱螺线法,提出了方便利用计算机计算的算法并对其进行了简化。研究了基于支持向量机进行井眼轨迹预测的方法,并建立井眼轨迹预测的支持向量机模型;对井眼轨迹相关数据进行预测,并利用预测的数据进行各测点的测斜计算,构建井眼轨迹预测点,方便对其进行三维可视化;对基于切片法的井眼轨迹桶状建模进行了研究,并构建各点井筒切片,依次连接各切片。利用OpenGL实现了通过井眼估计预测数据进行井眼轨迹的三维可视化可视化软件开发,为钻井生产的成功施工提供帮助和指导。

The problems in the construction process of drilling and drilling bottom blind measurement were studied. The current trajectory of 3D visualization system was designed. The trajectory measuring point range was analyzed. The cylinder helix method which is drilling in Chinese oil situation, was simplified for computer calculation. A well.bore trajectory prediction algo- rithm based on support vector machine was studied, and its model was established by using support vector machine. The pre- diction data of well trajectory, and the prediction data of each measuring point were calculated and well trajectory the prediction points were constructed for the convenience of 3D visualization of the barrel. The trajectory modeling based on slicing method was studied, as well as construction of shaft section. The OpenGL was used to realize the visualization of the borehole trajecto- ry by the prediction data of the borehole, which can help and guide the successful construction of the drilling production.
