摘要:

采用浸泡失重法、动电位极化曲线和电化学阻抗技术研究了L245钢在不同温度下的油气田模拟水中的腐蚀行为,采用SEM分析了腐蚀产物的表面形貌。结果表明：在饱和CO₂条件的溶液中,当温度从30 ℃升高至90 ℃时L245钢的腐蚀电流从66.1 μAcm^-2升高到177 μAcm^-2,说明L245钢在高温下反应比较剧烈。当温度从30 ℃升高至90 ℃时L245钢的电荷转移电阻从5155 Ωcm²减小到1182 Ωcm²,说明温度的升高减小了腐蚀反应的阻力。以上结果表明,在30~90 ℃时L245钢在油气田模拟水中的腐蚀速率随着温度的升高而加快,当温度升高至60 ℃时开始发生局部腐蚀并随着温度升高而加剧。

Abstract：

The corrosion behavior of L245 steel in simulated oilfield produced water was investigated by means of weight loss measurement, polarization curve measurement, electrochemical impedance spectra (EIS) and SEM. The results showed that the corrosion reaction of L245 steel is more intensive at higher temperature. When the temperature of the solution is elevated from 30 ℃ to 90 ℃, the corrosion current density of L245 steel in the solution with saturated CO₂ increases from 66.1 μAcm^-2 to 177 μAcm^-2 while the charge transfer resistance of L245 steel decreased from 5155 Ωcm² to 1182 Ωcm². The above results indicated that the corrosivity of oilfield produced water increased with the increasing temperature within the range of 30~90 ℃, localized corrosion of the steel occurred at 60 ℃, then the localized corrosion would be intensified when the temperature is elevated to 90 ℃.

Key words： L245 steel simulated oilfield water temperature corrosion rate
