Description

technical field [0001] The invention relates to the technical field of detection of safety conditions of underground gas storage wells, in particular to a detection device for corrosion and fatigue cracks of metal shafts of underground gas storage wells. Background technique [0002] Underground gas storage wells have the advantages of strong safety, large gas storage capacity, and small footprint, and have been more and more widely used. During the long-term use of gas storage wells, defects such as corrosion and fatigue cracks will appear in the metal wellbore, which has become an important factor affecting the safe use of gas storage wells. The SY / T 6535-2002 standard for high-pressure gas underground gas storage wells requires regular non-destructive testing of gas storage wells. The Chinese patent document "CNG gas storage well operation monitoring device" with patent number ZL200720079604.5 provides a CNG gas storage well operation monitoring device , the device is co...
