摘　　要：套管缺陷的模式识别及其预测是套管损坏实时监测和预测研究中的重要问题。结合具体实例 (中原油田某区油井套管缺陷图片 ) ,首先 ,利用坐标变换和图形处理方法 ,建立了套管缺陷图片恢复的二维数学模型 ,采用VC+ + 5 .0编程技术 ,对其进行二维模拟及效果分析 ;其次 ,借助于Photoshop软件 ,通过引入灰度函数的概念 ,对油 (水 )井套管缺陷进行三维模拟 ,有效地解决了套管缺陷图片重建问题 ;最后 ,利用灰度函数的性质 ,给出套管缺陷分类的新方法 ,并对其进行分类和使用寿命预测分析。为油 (水 )井套管缺陷识别及其寿命预测研究提供了新的途径。Pattern recogniti on of casing defect and its forecasting is an important issue in the process of real-time monitoring and forecasting of casing damages. Combined with specific examples (the photos of casing defects from a region of Zhongyuan oil field), th e 2D mathematical model that can restore the photos of casing defects is constru cted firstly by using coordinate transformation and image processing methods, wh ich by using Visual C~ ++ programming technology and the 2D simulation o f casing defects is presented and analyzed. Then, the 3D simulation of casing d efects of oil/water well is presented in the light of Photoshop software and gra yscale function, and the photos of casing defects of oil/water well are restored effectively. Finally, the casing defects are classified by using the properties of grayscale function, and the lifetime of casing is forecasted. A new way is g iven to recognize casing defects of oil/water wells and to forecast the lifetime of casing.
