The Preferred Criteria for Key Factors of Well Integrity Management in Underground Gas Storage in China
Natural gas storage facilities,as essential infrastructure for peak load management and reserves in China's energy strategy,hold paramount significance.However,the current integrity management of natural gas storage wells faces challenges,such as many relevant standards and complex management elements,which impede the development of well integrity management in gas storage facilities.This study addresses the abovementioned issues by systematically investigating and summarizing domestic and international laws,regulations,and standard and specifications related to gas storage facilities.With well integrity as the research focus,we have established a technical system for well integrity management and unearthed the key elements of well integrity management.For each key element,a benchmark analysis of standards and specifications was conducted and recommended execution standards were formulated.This study provides theoretical and deci-sion-making support for well integrity management in gas storage facilities,ultimately ensuring the safe operation of gas storage facilities.The findings of this research can serve as a reference and guidance for further advancing well integrity management in gas storage facilities.
