摘　　要：随着页岩气规模化开采,红星区块集输管道出现腐蚀穿孔现象,对页岩气安全生产造成严重威胁。为此,通过分析管道介质、现场工况并结合腐蚀模拟实验,采用浸泡试验法(点蚀分析、物相分析)和电化学测试法(电化学阻抗谱分析、极化曲线分析)研究红星区块页岩气集输管线腐蚀穿孔原因。为该地区针对性的防控措施设计提供技术支撑。With the large-scale exploitation of shale gas,corrosion-induced perforation have occurred in the transmission pipelines of the Hongxing Block,posing serious threats to shale gas safety production.This study analyzes pipeline media and field conditions,combining corrosion simulation experiments using immersion test methods(pitting analysis,phase analysis)and electrochemical testing methods(electrochemical impedance spectroscopy,polarization curve analysis).The findings provide technical support for targeted preventive measures in the area.
