摘要
在油田生产过程中结垢问题给油田企业带来巨大损失.常见的处理结垢的方法大致分为物理法、工具法和化学法.采用物理法、工具法处理结垢问题存在费用高、垢物清除效率低等缺陷,化学法因其操作简单、用量少、效果好等优点而被广泛采用.近年来,随着人们对环境保护意识的增强,聚天冬氨酸类阻垢剂被广泛研究.以马来酸酐和碳酸铵为原料合成了聚琥珀亚酰胺(PSI),在此基础上接枝丝氨酸、谷氨酸、酪氨酸并研究其阻垢性能.结果表明:谷氨酸接枝改性聚合物(GUL-PASP)阻垢效率为100%,具有优异的阻垢性能.
Abstract
In the oilfield production process,the problem of scaling brings huge losses to oilfield enterprises.Common methods of dealing with scaling are roughly divided into physical methods,tool methods and chemical methods.Using physical method and tool method to treat the scaling problem has the defects of high cost and low scale removal efficiency,and the chemical method is widely used because of its simple operation,low dosage and good effect.In recent years,with the enhancement of people's awareness of environmental protection,polyaspartic acid scale inhibitors have been widely studied.In this paper,polysuccinamide(PSI)was synthesized using maleic anhydride and ammonium carbonate as raw materials,and on this basis,serine,glutamic acid and tyrosine were grafted and their scale inhibition properties were studied.The experimental results showed that the scale inhibition efficiency of glutamic acid grafted modified polymer(GUL-PASP)was 100%,which had excellent scale inhibition performance.
