摘要:

腐蚀是制约多元热流体技术推广应用的关键因素。采用高温缓蚀剂后,防腐效果良好,但未获取现场腐蚀速率。针对此,研制了腐蚀监测装置,将两个P110钢挂片置于多元热流体注热管线中,现场实施多元热流体热采,10天平均腐蚀速率为0.090 5 mm/a,为均匀腐蚀,腐蚀产物主要是Fe₂O₃,验证了缓蚀剂防腐效果良好,满足目前多元热流热采防腐要求。 

Abstract:

Corrosion is the key factor restraining the promotion of multi-component thermal fluid technology. High temperature corrosion inhibitor has good protective effect, but the main corrosion rate could not be gotten .Hereto. A corrosion monitoring device is developed by placing two P110 coupons in the thermal fluid injection tube. After multi-component thermal fluid recovery for ten days,the corrosion is uniform, average corrosion rate is 0.090 5 mm/a, and the main corrosion product is Fe₂O₃. The result verifies the protection effect of the corrosion inhibitor, which can meet the anti-corrosion requirement for multi-component thermal fluid recovery.
