油田工艺管道腐蚀与防腐措施研究

Study on Corrosion and Anti-corrosion Measures of Oil Field Process Pipeline

油田工艺管道中输送的介质主要有石油、天然气、含油污水、高压水等,同时也包括酸、碱、盐等杂质。油气资源关系到国防安全和人民生活的方方面面,其重要性不言而喻,而由于腐蚀给油田工艺管道的安全运行带来严重危害,如腐蚀穿孔引起油、气、水的跑、冒、滴、漏造成的经济损失,对土壤、地下水、空气等造成环境污染,火灾、爆炸引起的人员伤亡等。因此,研究油田工艺管道内、外腐蚀的机理,有针对性的提出相应的防腐措施,延长管道的使有寿命,具有重要意义。

Oil,natural gas,oil-bearing sewage and high-pressure water are the main transportation media in the oil field process pipeline,including acid,Alkali,salt and other impurities.Oil and gas resources are related to every aspect of national defense safety and people’s life,and its importance is self-evident,such as corrosion perforation caused by oil,gas,water running,bleeding,dripping,leakage of economic losses,soil,groundwater,air and other environmental pollution,fire,explosion caused by casualties.Therefore,it is of great significance to study the mechanism of the internal and external corrosion of oil field process pipeline and put forward corresponding anti-corrosion measures to prolong the service life of pipeline.
