浅析海上油气平台钢结构腐蚀环境及防腐技术应用

Analysis on corrosion environment and application of anti-corrosion technology of steel structure of offshore oil and gas platform

海上油气平台是石油和天然气生产的关键设施之一,其安全性与可靠性对海洋环境下的油气生产至关重要。我国在南海、渤海、东海等海域的油气田开发建设中,面临着海上高/低温、高湿度、高盐分等恶劣环境条件。因此,分析了探讨海上油气平台钢结构的腐蚀特点、腐蚀机理以及目前海上油气平台钢结构主要的防腐蚀方法,为海上生产装置的安全运行提供有力的保障。

Offshore oil and gas platforms are one of the key facilities for oil and gas production,and their safety and reliability are critical to oil and gas production in the offshore environment.In the development and construction of oil and gas fields in the South China Sea,Bohai,East China Sea and other areas,China is faced with high/low temperature,high humidity,high salt and other harsh environmental conditions.Therefore,the corrosion characteristics,corrosion mechanism and main anti-corrosion methods of offshore oil and gas platform steel structure are analyzed and discussed,which provides a strong guarantee for the safe operation of offshore production equipment.
