摘　　要：为了控制CFD油田注水管线腐蚀情况,通过水样及管线运行工况分析,研究了管线腐蚀主要影响因素,分析表明CFD油田注水管线腐蚀受温度、Cl-及水体流动影响较大。为缓解管线腐蚀,采用旋转挂片法考察了几种缓蚀剂的缓蚀效果。室内试验表明在90℃,0.3MPaCO2+3.0MPaN2,转速451转/分的条件下,缓蚀剂YFHC-093具有良好的缓蚀效果。现场试验结果表明缓蚀剂YFHC-093加注浓度在25mg·L-1时,可将注水管线腐蚀速率控制在0.0366mm·a-1以下,低于油田腐蚀标准。In this paper, the operation of injection pipe and injection water was analysed through different methods. On this basis, a squeezing adsorptive corrosion inhibitor(YFHC-093) was synthesized in laboratory, the corrosion inhibition effect of YFHC-093 was attested to be good on injection water The corrosion rate of injection water could be limited under the standard(0.076mm·a-1) range, when the optimal concentration of YFHC-093was 25 mg·L-1.
