摘要
模拟含CO2 /H2 S高温高压井下多相流腐蚀环境 ,研究P110钢在模拟井下采油腐蚀环境条件下的腐蚀行为。结果表明 ,P110钢的平均腐蚀速率受到温度、CO2 分压和H2 S分压等参数的影响 ,其表面形成 3层形貌及成分各异的腐蚀产物 ,宏观腐蚀形态基本为均匀腐蚀 ,但是在扫描电镜下观察 。
Corrosion behaviors of P110 steel were studied in simulated CO_2/H_2S HPHT multiphase corrosion environment. The results showed that uniform corrosion rate of P110 in the experimental condition was effected by temperature, pressure of CO_2 & H_2S.The corrosion product scales of threes layers, which had different images and composites formed on the surfaces of corroded coupon. The morphology of corroded couple was uniform corrosion and localized corrosion.
