摘　　要：提出了一种油井井下管柱腐蚀状况监测技术 ,技术原理是运用 72 3分光光度计测定油井产出水中的铁离子含量 ,同时提供了腐蚀判断标准 ,它能很好地指导油井投加油井缓蚀剂治理腐蚀。矿场应用结果表明该技术能节约 5 0The technique for monitoring down-hole string corrosion status is introduced, the principle is to use 732 spectrometer for detecting the content of ferric ions in produced water, so as to provide criteria for judging the downhole corrosion, by which a good guidance is given for adding downhole corrosion inhibitors for corrosion prevention. Field application result indicates that 50% of corrosion inhibitors are saved by using the technique.
