摘　　要：某油气田原油生产管汇的背弯部分有明显减薄。通过对该生产管汇宏观形貌、材料成分、超声波测厚等的分析,并观察和分析了生产管汇腐蚀形貌和腐蚀产物,结合生产管汇的工况条件,对该生产管汇的失效原因进行了分析。结果表明:生产管汇腐蚀失效主要是由于冲蚀和垢下腐蚀共同作用引起的。The back bend of a crude oil production pipeline was thinned obviously.The macro-morphology,material composition and ultrasonic thickness measurement of the pipeline were analyzed.The corrosion morphology and products of the pipeline were observed.Combining with the working conditions of the pipeline sink for production,the failure reasons of the pipeline were analyzed.Results showed that the main cause of corrosion failure of production pipeline was the combined action of erosion and corrosion under scale.
