含辣素衍生结构疏水缔合聚合物的缓蚀性能研究
|
摘要
采用失重法、电化学方法以及表面观察方法对比研究了含辣素衍生结构疏水缔合聚合物P(AM-MAA-AMPSHDDE-SA)(PAMAHS)和聚丙烯酰胺对Q235钢在CO_2饱和的模拟油田采出水中的缓蚀性能。实验结果表明:相较于聚丙烯酰胺,PAMAHS对碳钢在油田水中的腐蚀具有较好的抑制作用,其缓蚀率随着聚合物浓度的增加而增大,缓蚀剂浓度为500mg·L~(-1)时,缓蚀效率能达到80.64%。因此,PAMAHS是一种混合抑制型缓蚀剂,其分子可以吸附在金属表面,形成一层具有保护作用的吸附膜,从而起到减缓腐蚀的作用。PAMAHS在碳钢表面的吸附行为符合Langmuir吸附等温式。
By means of weight loss method,electrochemical method and surface observation methods,the inhibition efficiency of the hydrophobic associating polymer P(AM-MAA-AMPS-HDDE-SA)(PAMAHS)containing capsaicin moietyfor Q235 steel in the CO_2 saturated simulated oilfield was studied.Results show that the corrosion inhibitor PAMAHSgave an good performance in inhibiting the corrosion of carbon steel in oilfield water,which was better than polyacrylamide.The corrosion rate increased as the polymer concentration increased,when the concentration of corrosion inhibitor was 500 mg·L~(-1),the corrosion inhibition efficiency can reach up to 80.64%.PAMAHS is a mixed type corrosion inhibitor.Thepolymer molecules can adsorbed on the metal surface,forming aprotective adsorption film which play agreat role in corrosion inhibition.Its adsorption behavior on carbon steel surface was according with the Langmuir adsorption isotherm.
