【摘要】 在油田开发过程中，井径测井是油水井检测与修复的重要方法。对于井径测井数据的处理方式，通常采用二维曲线和成像图进行分析，虽然也能够从图形中分析出油水井套管的状况，但缺乏直观性和清晰性。如果将井径测井数据的处理与三维可视化技术相结合，势必会将该测井技术的应用水平提高一个新台阶。井径测井过程中会产生大量丰富的测井数据，直观和高效地处理这些数据，将有助于全面地了解套管状况，同时也有利于油水井套管的检测及修复工作，从而保证油水井的正常生产。针对这一问题，本文将使用三维重构中的面绘制技术，对井径测井数据进行分析并重构出套管的三维表面模型，最终开发出油水井套管三维可视化系统。根据实际应用需求，对基于视图的套损类型自动识别方法进行了研究，并进行了相关的实验，实验结果验证了该方法能取得较好的效果。本文的研究工作主要包括下面三个方面：本文首先分析了井径测井原理，应用三维重构的面绘制技术，使用JOGL作为图形开发工具，设计了油水井套管三维可视化模型，并最终实现了油水井套管三维可视化系统。其次，本文针对油田中的井径测井数据的特征，将基于视图的三维物体识别方法应用到套损类型自动识别过程中。通过实验验证，该方法能够较好地分析出常见的套损类型，有助于高效、准确地处理井径测井数据。最后，本文应用数学领域的KPCA方法完成特征值的抽取及降维操作，改进了基于视图的套损类型识别方法的效率。通过对比实验结果分析证明，在不影响分析结果准确性的前提下，该方法可有效地提高三维物体识别效率。更多还原

【Abstract】 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.更多还原
