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.
