油井采出液将会对金属设备造成腐蚀 ,所以以有机酸、多胺等为原料合成了GS 1油井缓蚀剂。对富含H2 S、CO2 及盐的污水 ,该缓蚀剂添加量为 50mg/L时 ,缓蚀率可达 80 %以上。静态腐蚀速率小于 0 .0 76mm/a,现场应用效果显著。该缓蚀剂原料来源广、生产过程简单、成本低 ,将是一种较有应用前景的油井缓蚀剂 Oil well production fluid will cause corrosion on metal equipment, so organic acid, polyamine and other raw materials for the synthesis of GS 1 oil well corrosion inhibitor. For the sewage rich in H2S, CO2 and salt, the corrosion inhibition rate can reach over 80% when the dosage of this corrosion inhibitor is 50mg / L. The static corrosion rate is less than 0.076 mm / a, and the field application has remarkable effect. The corrosion inhibitor wide source of raw materials, the production process is simple, low cost, will be a more promising oil well corrosion inhibitor
