基于Web的三维实时井眼轨迹可视化方法研究与实现

Research and implementation of Web-based 3D real-time visualization of wellbore trajectory

针对基于Web的实时三维可视化应用需求,结合邻近井段的结构形状、变化规律,改进了贝塞尔曲线拟合算法,提高了测斜数据处理速率和曲化度,并采用Away3D技术实现轨迹的三维展示。应用结果表明,轨迹绘制细腻流畅,系统具备良好的实时性。

This paper aims to provide a method to meet the needs of the application of Web-based real-time 3D visualization. According to the structure and change rule of neighboring well segments,we improved Bezier curve fitting algorithm and increased inclinometer data processing rate and the curve degree. Meanwhile, we used the Away3D technology to achieve a 3D visualization of trajectory. Application shows that the trajectory is delicate and smooth, and the instantaneity of this system is good.
