Drilling Geological Engineering Drawing Technology Research And Implementation

Drilling geological engineering drawings is an important basic data needed in oilfield drilling process,which runs through the whole process of oilfield exploration and development,geological static research,drilling dynamic analysis and production management.Drilling geological engineering drawing software of traditional forms,the general is poor,lack of professionalism,poor data sharing.therefore,to solve these problems,the software engineering technology,computer graphics technology,database technology integration,design a system for oil field exploration and Drilling geological engineering drawing software development research the goal of this article.In this paper,the overall structure of the drilling geological engineering drawing system is designed,and it is mainly carried out from three aspects.First,the data processing is carried out,and the original data of the well is converted to the visualization of 3D well trajectory through the calculation of diagonal calculation and interpolation.Secondly,the use of data mapping,well structure and column drawing map using texture mapping method,so as to solve the downhole tools and column in joint dislocation trajectory arc,while providing a solution for vector legend need complex pattern filling modeling difficulties;automatic annotation algorithm based on grid and avoidance rules,solve the problem of overlapping mark wells bitmap data,improve the efficiency of drawing mark;lithology pagination form drawing,lithology and lithology pattern symbol description text to fill in accordance with certain methods.Finally,user interaction operation can be carried out for rotary operation of wellbore trajectory.In multiwell trajectory visualization and well location visualization,different well objects can be displayed or hidden,and the outer diameter ratio coefficient can be zoomed in the wellbore structure and the pipe graph.Finally,the characteristics and advantages of VC++ and OpenGL technology in the visualization of C/S mode are analyzed,and the drilling geological engineering drawing system is realized.The system can provide help and reference for the drilling technicians,and it has certain practical value.
