摘　　要：高压储气井承装介质主要是压缩天然气,其是城市的调峰调压装置,被广泛应用于国内压缩天然气加气站。由于储气井受到内外在环境的影响,出现不同程度的腐蚀现象,正常运行受到影响。分析了高压天然气储气井内、外腐蚀机理,研究了腐蚀对于机械性能影响的原因,提出了强度校核的改进算法。The bearing medium of high-pressure gas storage well was mainly compressed natural gas, which was a peak and pressure regulating device in cities and was widely used in domestic compressed natural gas filling stations. Due to the influence of the internal and external environment, the gas storage well was corroded to varying degrees and its normal operation was affected. The mechanism of internal and external corrosion of high-pressure natural gas storage wells was analyzed, the reasons for the impact of corrosion on mechanical properties were studied, and an improved algorithm for strength check was proposed.
