Well casing integrity is vital for the safe operations of oil wells, and also significant to detect well casing defects. Magnetic flux leakage (MFL) detection technology is widely-used in detecting the defects of various pipelines. Owing to the very complicated environment where well casing is laid in, the system which based on magnetic flux leakage technology is not mature yet to detect well casing...
