The 3D simulation and recognition method of oil/water well casing defects

DOU Ji-hong; et al. (Northwest University, Shnxi 710069, P. R. China).  
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.
