摘　　要：油水井套管的腐蚀问题一直困扰着油田的正常生产,油水井套管腐蚀套管损坏,会造成注采井网失调,水驱动用程度低、剩余储量无法采出,且动态监测资料录取困难,导致措施及管理费用增加,严重影响油田稳产及开发效益。因此,针对延长油田油水井套管严重的套损问题,开展了腐蚀原因及防治技术研究,为延长油田套管服役年限的延长提供技术保障,确保油水井正常生产。The corrosion problem of oil and water well casing has been puzzling the normal production of the oilfield.The corrosion of oil and water well casing will lead to the imbalance of the injection production well pattern,low water drive utilization,and the remaining reserves cannot be recovered.In addition,it is difficult to record the dynamic monitoring data,which will lead to the increase of measures and management costs,and seriously affect the stable production and development benefits of the oilfield.Aiming at the serious casing damage problem of oil and water wells in Yanchang Oilfield,this paper has carried out research on corrosion causes and prevention technologies to provide technical support for prolonging the service life of oil and water wells and ensure the normal production of oil and water wells.
