多元热流体腐蚀监测装置研制与应用评价

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 5mm/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。...

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 5mm/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.
