Abstract: The casing defect concludes both mechanical and chemical damage, which has
large influence and damage on well safety or oil and gas bearing layers. Based on the basic
principles of pulsed eddy current technology, this paper proposed the ideas of the
non-destructive testing for metal casing. This method uses a bipolar pulse as an incentive, the
detection signal includes the casing response for multiple frequency. So it can get broadband
detection. By ANSYS finite element simulation software, the induced electromotive force in
receiving coils is numerical calculated. Furthermore, this paper in-depth studies the
characteristics of electromagnetic response for cavity damage and cracks in metal casing. This has
laid a good foundation for qualitative grasp the casing damage conditions.
