摘　　要：为解决当前井筒可视化实现过程复杂、展示内容单一、实用性不强的问题,基于Three.js框架提出了一种适用于实际井眼轨迹与三维可视化井眼轨迹坐标信息的数据处理与映射方法,研究了一种新的基于Web端的三维井筒几何模型及井筒信息可视化方法。结果表明:通过该方法可以更加直观地观察井眼轨迹变化规律,展现反映井径变化的三维井筒。同时,自然伽马值、环空压力等测井录井信息以及地层岩性信息也可以较为方便地沿井筒通过颜色或者井径变化所展现。此外,通过敏感性分析,揭示了可视化效果与井径缩放因子、井眼轨迹缩放因子、井筒信息缩放因子的规律,有效提高模型仿真可视化效果,还提供一种用于展示井筒内部数据变化规律的井筒漫游方法。研究结果为油气钻探过程及钻遇地层的直观呈现提供了新方法。In order to address the issues of complexity in current wellbore visualization process,limited display content,and lack of practicality,a data processing and mapping method based on the Three.js framework for practical wellbore trajectory and 3D visualization of wellbore coordinate information was proposed.It can be shown that this method allows for more intuitive observation of wellbore trajectories and the visualization of 3D wellbores with diameter variations.Additionally,logging information such as natural gamma values and annular pressure,as well as mudlogging information such as lithological classification may be readily presented along wellbores via color or diameter variations.Furthermore,the relationships among visualization effects and factors such as wellbore scaling,trajectory scaling,and wellbore information scaling are revealed by sensitivity analysis.The emulation and visualization effects of the model are effectively improved.In summary,a wellbore navigation method for intuitive presentation of oil and gas drilling processes and formations along the borehole is provided by this research.
