海底管道发生泄漏的原因有多种,例如外力损伤、内部腐蚀等。南海某油田海底管道在投产几年后发生了腐蚀泄漏,通过对海底管道泄漏前的生产数据进行管道失效长度分析、冲蚀分析和腐蚀速率模拟计算,给出了该管道发生腐蚀泄漏的原因,为以后海底管道的安全运行提供借鉴。
海底管道髮生洩漏的原因有多種,例如外力損傷、內部腐蝕等。南海某油田海底管道在投產幾年後髮生瞭腐蝕洩漏,通過對海底管道洩漏前的生產數據進行管道失效長度分析、遲蝕分析和腐蝕速率模擬計算,給齣瞭該管道髮生腐蝕洩漏的原因,為以後海底管道的安全運行提供藉鑒。

There are many resons for the leakage of subsea pipeline such as the damage of external force, internal corrosion, etc. A subsea pipeline in South China Sea was leaked because of corrosion. With the operation data before the leakage, the pipeline failure length analysis, erosion analysis and simulate computation of corrosion rate was carried out. The corrosion leakage reason of this pipeline will provide some practices for safe operation of similar pipeline.
