Application Research Of Oil-water Wells Casing3D Visualization Based On Surface Rendering

During the exploitation process of oilfield, the caliper logging is an important method ofthe oil-water well detection and repairing. For the method of dealing with caliper logging data,usually use2d curve and imaging drawing to analysis, although could also analyze theoil-water wells telescopic situation from drawing, but lack of intuitive and clear. If combinedthe dispose of caliper logging data with3D visualization technology, will certainly promotethe application of this logging technology up to a new stage.We can get large amounts of logging data during the process of the caliper logging, toprocess these data intuitively and efficiently, so can understand the state of casingcomprehensively, and this will be good for the oil-water wells detection and repairing toensure the normal production of oil Wells. According to this problem, this article will use thesurface rendering technology in3d-reconstruction to analyze the caliper logging data andreconstruct the telescopic3d surface model, and develop oil-water well telescopic3dvisualization system eventually. According to the actual application requirements, we study theautomatic identification method of casing damage type based on view and do some experiment.Experimental results show that the method can obtain good effect.The study mainly includes the following three aspects:Fistly, this paper analyzes the caliper logging principle, use the face rendering technologyof3D reconstruction, JOGL as graphics development tools, designed the oil-water wellscasing3D visualization model, and ultimately achieve the oil wells casing3D visualizationsystem.And, according to the characteristics of caliper logging data in oil field, we will introducethe3D object recognition method based on view into the automatic recognition process ofcasing damage type. Through the experiment,this method can well analyze the common casingdamage types, and it is helpful to apply the caliper logging data efficiently and accurately.Using KPCA in mathematics field, we complete characteristic value of the extraction anddimension reduction operation and the efficiency of based on the view of casing damagerecognition method is improved.Through comparing and analysising the experimental results,it can improve the efficiency of recognition effectively without affecting the accuracy of theresults.
