| 摘 要： | 以丙烯酸、甲基丙烯酸、丙烯酸丁酯、甲基丙烯酸甲酯、苯乙烯等为原料,在胶束水溶液中合成了一系列非聚醚型破乳剂.采用试瓶法对模拟采出原油乳状液进行了破乳实验研究.结果表明,含有亲水性基团的非聚醚型破乳剂,由于分子结构的双亲性,有利降低油水界面膜强度和增加动态界面活性,使其破乳效果优于油溶性破乳剂的破乳效果,但过强的亲水性会... |

| Abstract: | A series of non-polyether demulsifiers were prepared by micelle water solution polymerization with raw materials of acrylic acid,methacrylic acid,butyl acrylate,methyl methacrylate,styrene, etc.The demulsibility of the prepared crude oil-in-water emulsion was carried out by the above demulsifiers with the bottle test method.The effect of constitutes and structure of the demulsifier molecules on the demulsibihties was studied by the experiment of demulsifying simulated crude oil emulsion. The experimental da... |
