南海某气田C平台腐蚀环境探讨

Discussion on the Corrosion Environment of the Platform C in the Oil-Gas Field in the South China Sea

根据１９９７年２月国家海洋局第一海洋研究所和广州二海海洋勘察公司对北部湾南部某气田海区海水及沉积物腐蚀性因子调查的资料，综述了该海区电阻率、溶解氧、Ｆｅ３＋／Ｆｅ２＋、Ｅｈ和有机质等腐蚀因子的特征．对腐蚀环境进行了综合分析，指出调查区海水腐蚀情况与临近海区海水接近，各站表层海土腐蚀性偏向于较强级，从而提出了防腐蚀对策。

The paper briefly introduces the features of corrosion factors such as respective dissovled oxygen Fe3+, Fe2+, Eh, organic material and so on based on the data of corrosion factors of seawater and sediment in the Oil-Gas Field of the Beibu Gulf investigate by the First Institute of Oceanography, SOA and the Oceanic Prospecting Company in GuangZhou in Feb. 1997. It comprehensively analyses the corrosion environment and points out that the condition of seawater corrosion in the studied area is close to that in the adjacent sea area and that the corrosiveness of the marine sediment in each station tends to be strong.
