南海某气田B平台腐蚀环境探讨

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，概述了该海区电阻率、溶解氧、Fe^2 /Fe^2 、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邻近海区海水接近，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。

DISCUSSION ON THE CORROSION ENVIRONMENT OF THE PLATFORM B IN THE OIL GAS FIELD IN THE SOUTH CHIHA SEA

The paper briefly introduces the features of corrosion factors such as resistivity, 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 Beibuwan Bay investigated 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 corrosive condition in the investigated sea area has a close relation to the sea water condition in the adjacent sea area and that the corrosion of the marine sediment is rather stronger in each observatory station.
