井眼轨迹计算及可视化研究现状

Status of calculation and visualization research on well trajectory

对现有的井眼轨迹计算方法进行对比分析,得出圆柱螺线法和最小曲率法计算精度较高,具有较好适用性。通过总结井眼轨迹可视化研究相关算法及可视化软件发展现状认为,可视化研究趋于普遍适用性、功能多元性和更加智能性方向发展。同时,对利用方位伽马测井曲线识别储层界面方法进行探索性研究。

The existing calculation methods of wellbore trajectory were compared and analyzed,and the authors found the cylinder helix method and minimum curvature method in high accuracy and have better applicability. Through summarizing the status in development of well trajectory visualization algorithm and visualization software,it is concluded that visualization research tends to be in general applicability,functional diversity,and more intelligent direction of development. At the same time,the research on the method of identifying the reservoir interface by using the directional gamma log curve is studied.
