| 摘 要： | 弱碱三元复合驱(ASP)技术在提高原油采收率的同时由于诸多优点,已逐渐取代以往强碱三元复合驱技术在大庆油田应用.但目前国内外对ASP的研究还仅限于驱油效果,而对其溶液的腐蚀行为的研究甚少.ASP采出液中弱碱三元成分的存在,会提高钢的腐蚀性且腐蚀情况复杂.本文采用腐蚀挂片试验法、电化学测试等测试技术系统研究油田管道用钢(10钢、20钢、45钢、1Cr18Ni9Ti、X70钢)和储罐用钢(Q235钢)在不同浓度、不同温度三元复合驱溶液中的腐蚀行为,测试钢在不同pH值的ASP溶液中的交流阻抗图(EIS),获得腐蚀动力学相关参数,用扫描电镜(SEM)、能谱仪(EDS)、X射线衍射(XRD)等技术分析腐蚀产物形貌并确定腐蚀产物成份,为钢在弱碱三元复合驱采出液中的腐蚀机理进一步研究提供依据.

| Abstract: | The ordinary Alkali-Surfactant-Polymer(ASP)flooding was replaced by weak base ASP flooding for many merits,which had a promising application in Daqing oilfield.However,the key study present on ASP was limited to the flooding efficiency,and the corrosion behavior of ASP solution is really few.Also,the addition of sodium carbonate may improve the complexity of corrosion.The corrorion behavior of common oil pipeline steel(10,20,45,1Cr18Ni9Ti and X70)and storage kettle steel Q235 in weak base ASP solution were ... |
