CORR11546A型缓蚀剂在YB气田项目的应用

Application of corrosion inhibitorCORR11546A in YB gas field

YB气田属于典型的CO2腐蚀条件,通过对YB气田现场工况的调研,分析腐蚀因素,对CORR11546A缓蚀剂分别进行室内和现场试验。室内实验表明CORR11546A在缓蚀剂溶液中预先经过成膜处理后,可以达到良好的腐蚀防护;现场试验通过对比加注CORR11546A缓蚀剂前后腐蚀挂片结果,分析该缓蚀剂在YB酸性气田中的应用效果,腐蚀防护率可达85%,这对CORR11546A在酸性气田中应用具有一定指导意义。

YB gas field is a typical CO2 corrosion condition.Based on the field investigation and analysis of corrosion factors of YB gas field,laboratory experiment and field tests were carried out on CORR11546A corrosion inhibitor.The experiment showed that CORR11546A can achieve good corrosion protection after pre film forming treatment in the corrosion inhibitor solution.In the field test,the application effect and corrosion protection rate of the inhibitor in YB acid gas field were analyzed by comparing the results of corrosion coupons before and after adding CORR11546A corrosion inhibitor It can reach 85%,which has certain guiding significance for the application of CORR11546A in acid gas field.
