摘要
本文主要以顺丁烯二酸酐和丁二酸酐作扩链剂对DA系列聚醚进行改性并用渤海原油对其产物进行破乳评价 ,从而得出破乳效果与扩链剂、反应时间的关系。研究表明 ,未扩链改性的聚醚对渤海原油几乎没有作用 ,DA系列聚醚改性后对渤海原油的破乳效果明显增强 ,但聚醚和扩链剂不同 ,其改性产物的破乳效果不同。以顺丁烯二酸酐作扩链剂改性的产物 ,其破乳效果随反应时间增加而呈先增加后下降的趋势 ;以丁二酸酐作扩链剂时 ,DA0 5和DA10的扩链产物随扩链时间的增加而增加 。
This paper mainly discusses the modification of a series of polyethers by extending reaction with maleic anhydride and succinic anhydride. The demulsifying property of the modifiers was evaluated by the demulsifying test with Bohai crude oil. The relation between the demulsifying effect and the chain extenders and the extending reaction time was obtained from the demulsifying experimental results.
