| 针对随钻过程中数据的复杂多样性以及井下信息可视化的重要性,以随钻井轨迹数据和随钻测井数据为研究对象,研究并给出随钻井筒可视化建模的方法,建立立体井筒模型。基于成像原理给出钻遇地层可视化建模方法,建立地质属性映射模型,采用纹理技术实现二者的有机融合,真正实现随钻井筒的三维可视化。利用Open Inventor图形开发工具包,实现三维井筒的绘制和钻遇地层信息在三维井筒上的展示。 |

| Abstract: |
| To address the complex nature and the importance of visualization of downhole data in geosteering, we developed methods for wellbore visualization modeling and established a 3D model of wellbore, using well trajectory data and logging-while-drilling data. Based on the imaging principle, we developed methods for formation visualization modeling while drilling, and built a geological attribute mapping model. Using texture mapping technology, we fully integrated the two models mentioned above, and achieved 3D visualization of drilling wellbore. Using Open Inventor graphics development kit, we illustrated how to draw 3D wellbore and display drilling formation in 3D borehole. |
