| 摘 要： | 根据 1 997年 2月对南海北部湾东方 1 -1气田海区海水及沉积物腐蚀性因子调查的资料 ,概述了该海区电阻率、溶解氧、Fe3+ /Fe2 +、Eh、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。

| Abstract: | Based on the data of corrosive factors of seawater and sediment surveyed in the Dongfang 1 1 gas field sea area of the South China Sea in February, 1997, the characteristics of corrosive factors including resistivity, dissolved oxygen, Fe 3+ /Fe 2+ , Eh and organic matter in the sea area are summarized. It is shown from the comprehensive analysis of the corrosion environment that the seawater corrosion conditions in the surveyed area are close to those in the adjacent sea area, the corrosivity of the surficial bottom sedimnt in the area is stronger, and the anticorrosive measures are then proposed. |
