| 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. |
