摘要
伊拉克鲁迈拉油田位于波斯湾沿岸,地下水位较高,原油储罐附近的土壤为盐碱性。罐区储罐底板内壁主要接触含油淤泥和污水。因此储罐底板两侧环境均具有很强的腐蚀性。由于近20年该油田疏于管理,很多防腐设施和涂层受到破坏,引起部分储罐发生腐蚀泄漏。为探明当地原油储罐腐蚀穿孔的原因,并找出科学合理的防腐蚀对策,保证鲁迈拉油田的平稳生产,采用现场勘查、实验室水质检验、形貌观察、能谱分析等多种手段,从储罐的材质、当地环境、储罐存储介质、腐蚀形貌等方面对储罐底板的腐蚀原因进行分析;并根据分析结论推荐了储罐的修复方案和罐内外防腐措施。(图3,表1,参10)
Iraq＇s Rumaila Oilfield, located in the Persian Gulf Coast, features high underground water level and saline soils around crude oil tanks. The inner walls of tank bottoms contact with sludge and sewage, so both sides of the tank bottom are exposed to corrosive environments. Mismanagement in the past 20 years has led to damages to anti-corrosion facilities and coating, causing leakage in some tanks due to corrosion. To find out the reasons for corrosion-induced piercing in local crude oil tanks and define scientific and rational anti-corrosion measures, the tank bottoms in Rumaila Oilfield are investigated with respect to materials, local environment, storage media and corrosion morphology. For this purpose, methods including field survey and laboratory water quality/morphological observation and spectrum analysis are used. Finally, this paper proposes a restoration program and countermeasures to avoid corrosions inside and outside the tanks. （3 Figures, 1 Table, 10 References）
