Research of 3D Visualization for Wellbore Trajectory

This paper deals with the analysis of the modeling deficiencies of the traditional 3D well bore trajectory and puts forward a new method of slice-based modeling for the tubular well bore trajectory. The method implements the 3D tubular well bore trajectory seamless connection efficiently and conveniently without interpolation smoothing treatment of the well bore trajectory's bender. In order to directly observe, analyze and effectively control the drilling trajectory for the drill staff, the paper implements the 3D tubular well bore trajectory based on virtual reality technology and provides a flexible human-computer interaction function. It also details in the well bore trajectory modeling and 3D visualization followed by an application example.
