A phosphorylmethylated fatty acid amide is prepared and evaluated as corrosion inhibitor GS 1(40% solution) GS 1 at use level 50 mg/L decreases the corrosion rates of carbon steel A3 and N80 in the simulation and oilfield produced waters by >80%.

• 合成并评价了油井缓蚀剂GS 1 (膦甲基化的有机酸酰胺溶液 ,有效成份含量 4 0%25 ) ,加量为 50mg/L时 ,无论在模拟油田污水中 ,还是油井采出液中 ,对N80钢、A3钢的缓蚀率均在 80%25以上 ,优于现用的两种缓蚀剂。
