研究了在模拟大庆油田井下的腐蚀环境中Ni-Co-Cr-Mo合金MP35N的抗CO2腐蚀性能. 用高温高压釜进行了Ni-Co-Cr-Mo合金MP35N的腐蚀实验, 并采用SEM、EDS和XPS等测试手段分析了腐蚀产物膜的形貌和组成. 结果表明: Ni-Co-Cr-Mo合金MP35N的腐蚀速率在所有实验条件下均属于轻度腐蚀, 表面腐蚀产物膜较薄, 整体属于均匀腐蚀. 腐蚀产物膜主要由Co、Cr、Ni、Mo的氧化物和氢氧化物构成.
The resistance to CO2-induced corrosion of Ni-Co-Cr-Mo alloy MP35N was investigated in high temperature and high pressured CO2-containing waters in an autoclave, stimulating the corrosion environment of Daging oilfield. The morphologies and compositions of corrosion scales were examined by means of SEM, EDS and XPS. The results showed that the corrosion of Ni-Co-Cr-Mo alloy MP35N in the desired test conditions all belonged to slightly uniform corrosion. The corrosion scales was thin with apparent furrows on the surface. The main components of the corrosion scales on the alloy were oxides and hydroxides of Co, Cr, Ni and Mo.
