[0001] The utility model relates to the technical field of oil pipe detection, in particular to oil pipe nondestructive detection equipment. Background Art
[0002] Oil pipes are pipelines that transport crude oil and natural gas from oil and gas layers to the surface after drilling is completed. They are used to withstand the pressure generated during the mining process. Oil pipes are industrial products and are generally used in oil well operations. They play a role in oil production, gas production and water injection in oil wells.
[0003] When oil pipes are used for a long time, they need to be inspected to avoid affecting the oil production operation of the oil well due to damage to the oil pipe. The existing inspection method generally uses ultrasonic non-destructive testing, but since the oil pipes are long, it is not convenient for ultrasonic probes to perform flaw detection on the entire surface of the oil pipes, that is, it is impossible to determine the specific damage location of the oil pipes, and it is impossible to accurately locate and detect the local damaged areas. Therefore, further improvements can be made. Utility Model Content
