| 摘 要： | 研究了青海油田集输管线腐蚀的主要原因。结果表明：水样中高氯离子含量、高总含盐量、高矿化度是影响管线腐蚀加剧的重要原因。细菌微生物参与了管线的腐蚀反应，它与溶液中氯离子共同作用，使管线局部腐蚀加剧。同时管线还受到由硫化氢引起的应力腐蚀作用，使得管线既可能由于坑蚀或孔蚀导致腐蚀穿孔，还可能由于应力腐蚀而导致突发性开裂。

| Abstract: | The main reason for corrosion of oil pipelines in Qinghai oil field has been studied. High concentration of Cl-,salts, high mineral degree are main factors to influence the corrosion of pipelines. Bacteria also assist corrosion. Localized corrosion induced by Cl- and bacteria was accelerated.Simultaneously the pipelines also suffer from SCC induced by H2S. The pipeline steel could possibly leak by pitting or abrupt fracture by stress corrosion. |
