摘要: 为研制耐温稠油降粘剂,以丙酮作溶剂,采用氯乙酸法合成了氧乙烯链节数分别为4、6、8、10、15的5种壬基酚聚氧乙烯醚乙酸盐(以OPC-n表示,其中n表示氧乙烯链节数),评价了这些表面活性剂对取自胜利油田、辽河油田的7种稠油的乳化降粘性能。结果表明,OPC-8的降粘能力最好,当质量分数为0.03%~0.1%时, 7种稠油的降粘率均高于90%。该降粘剂具有较高的耐温能力,在300℃下加热3h,其浓度没有发生明显变化。对特稠油和超稠油的开采具有指导意义。

Abstract: Using acetone as solvent, a series of octyl phenol polyoxyethylene ether carboxylate (abbreviated as OPC n, where n is oxythylene chain length ) with different oxythylene chain length ranging from 4 to 15 are prepared from octylphenolpolyoxyethylene ether and chloroacetic acid, and their minimum concentration needed to reduce the viscosity of 7 crude oil samples from Shengli and Liaohe oilfield is measured. The result indicates that, OPC8 is the most efficient among the resultants, when mass fragment is 0.03%~0.10%, the viscosity reducing ratio of this surfactant for Shengli and Liaohe viscous oil all can be above 90%. In addition, the temperature resistance property of this viscosity reducer is studied. The result shows that, the concentration of OPC 8 changes little after being heated at 300℃ for 3 hours.

Key words: viscous oil, viscosity reducer, temperature resistance, amphoteric surfactant, steam huff and puff
