摘要

Gas storage wells are widely used in the storage of compressed natural gas because they are installed in the ground, have a small footprint, and can resist atmospheric corrosion. With the wide application of gas storage wells as CNG natural gas storage equipment in my country, regular inspections are required to ensure the safe use of gas storage wells. In the daily use and monitoring of gas storage wells, there are examples of leakage caused by corrosion on the inner and outer walls of the gas storage well, which burst and cause the gas storage well to fail, causing huge economic losses and safety accidents. This article mainly introduces the technical principle of ultrasonic flaw detection, the application of ultrasonic flaw detection in the flaw detection of gas storage wells, and the data analysis after field use.
