摘　　要：在模拟高酸性气田集输系统条件下,研究了不同加注方式下咪唑啉和有机胺复配缓蚀剂的缓蚀效果,用扫描电镜和X射线衍射仪对试验结果进行了分析,结果表明,三种加注方式下缓蚀率均在75%以上,涂膜+批加注条件下缓蚀效果最好。The effect of injection modes on corrosion inhinition efficiency of the imidazoline and organic amine comlpex inhibitor under the condition of simulating gas-gathering line system of high sour gas well was evaluated by using SEM and XRD.The results indicated that the corrosion inhibition efficiency for three different injection modes was all above 75%and the mode of coating ＋ one-off injection was the best.
