基于Web 3D的钻孔运动轨迹三维建模关键技术

A method of 3D modeling of drilling trajectory based on Web 3D

钻孔数据是地质研究的基础数据,广泛应用于石油、煤炭、地质勘查等行业。利用钻头在地下不同深度的三维坐标数据结合虚拟现实建模语言(VRML)与Web技术,形成基于B/S架构的钻头运动轨迹自动建模与成图系统,实现在网页界面中自动形成并显示钻头运动轨迹的功能。文中的钻孔三维建模方法准确可靠,可实现在浏览器界面展示动态三维钻孔运动轨迹和水平投影,直观地显示出钻头在地下的运动轨迹和钻孔水平偏斜程度。

Drilling data is the basic data of geological research and is widely used in petroleum,coal,geological exploration and other industries.By using the three-dimensional coordinate data of the bit in different depths of the ground and combining virtual reality modeling language(VRML)and Web technology,an automatic modeling and mapping system of the bit’s motion trajectory based on B/S architecture is formed,which realizes the function of automatically forming and displaying the bit’s motion trajectory in the web interface.The proposed method is accurate and reliable.It can display the dynamic three-dimensional drilling trajectory and two-dimensional plane projection in the IE browser,and visually show the drill’s underground trajectory and the horizontal deviation degree of the drilling hole,which can be used as a reference for further study of the inclination of the drilling hole.
