Abstract

Abstract: Aiming at the problem of casing damage and corrosion detection and recognition, four kinds of damage and corrosion types are defined, and the pattern matching recognition of damage and corrosion characteristics is studied. The traditional image contour tracking and extraction are optimized and improved. The casing damage image is transformed into three-dimensional one, and the feature pattern recognition technology of three-dimensional image is used to search a three-dimensional damage-corrosion closure volume, by constraining on distance thresholds between data points and numerical thresholds in casing damage data sets. Different three-dimensional damage-corrosion closure volume represent the different characteristic subsets of damage and corrosion shapes. The axial and radial features of the feature subset are extracted, and the extracted features are matched with the standard corrosion pattern features to accurately evaluate the damage-corrosion type of casing. Practical application shows that it can accurately detect ring corrosion, line corrosion, general corrosion and isolated corrosion, and solve the problem of identifying the corrosion type of casing damage at present.
