| H2S, CO2corrosion is a common type of corrosion in the oil industry in theworld, which also had a very big impact on the development of China’s petroleumindustry. In the H2S and CO2corrosion protection, corrosion inhibitor is an importantmeans of corrosion protection. At present, the inhibitor which resists highconcentration of H2S and CO2is reported rarely, and the price is higher, and also hashigh pertinence, Highly targeted, which needs further research and development.In this paper, Hong75doped conveyance contains a lot of HCO3-/CO32-, waterquality is the typical high-sodium bicarbonate water quality, determine the corrosionmechanism:Hong75doped water delivery caused fracture mode and the overallcorrosion along the grain IGSCC and transgranular TGSCC,and caused piping andequipment stress corrosion cracking （SCC）.H2S in the oilfield produced water willaccelerate stress corrosion of piping and equipment.Adopt Ming Fu of Changchunproduction,the M1corrosion inhibitors of Tianjin Chemical Reagent the Wuchang andinhibition efficiency reached90%.（SCC） is the most effective way to uselow-strength steel, corrosion inhibitors, and protective coating. |
