Research on Drilling Section Automatic Generation Methods

On the basis of analyzing the Coalfield material, starting from the organization methods of borehole data, we make a study and analysis for the drilling section automatic generation, profile line smooth processing and litho logy decorative pattern filling, etc. According to the problem of smooth processing of profile line, respectively use Bezier curve and B spline curve two methods on the profile line smooth processing, through analysis and comparison, we can make a conclusion that the smooth processing effect of B spline curve is better than Bezier curve. Based on VC++6.0 platform, and mainly adopted MFC secondary development method, combined with OpenGL 3D graphics library, take the practical borehole data of HUANGLONG as an example, realized the drilling section automatic generation, and also made inter-checking between graphics and their attributes. Experiment shows that the methods of this article used are feasible, the effects are good, and satisfy the demands of actual work.
