摘要: 本文针对克拉玛依油田现有的稠油破乳剂破乳效果较差这一现状，以OF271型多胺类嵌段聚醚为基础物，通过甲基丙烯酸先酯化后聚合的方法进行改性。在预混合温度为120℃，酯化温度为85℃，酯化时间8 h，聚合温度85℃，聚合时间5 h，的最佳条件下合成了甲基丙烯酸改性的OF271型破乳剂。采用红外光谱(IR)对其结构进行了表征，并对其不同浓度水溶液的表面张力进行了测定。在75℃下，改性后的OF271原油破乳剂在有效加药浓度减少40%的条件下破乳效果高于现有破乳剂。
Abstract: In order to solve the poor effect of demulsifier in Karamay oilfield, methacrylic acid esterification and polymerization with the base material of polyamine block polyether OF271 to improve the dehydration effect. The modified demulsifier was synthesized under the optimum conditions of pre-mixing temperature 120˚C, esterification temperature 85˚C, esterification time 8 h, polymeri-zation temperature 85˚C, polymerization time 5 h, mechanical stirring. With a 60% effective dosing concentration at 75˚C, the demulsification effect is higher than the existing demulsifier. The modified demulsifier was characterized by infrared spectroscopy (IR) and indicating the acrylic acid complete reaction.
