摘要： 针对实验室配制的克拉玛依原油乳状液, 研制出低温高效的有机硅改性聚醚破乳剂, 通过单因素实 验确定适宜合成条件为: 含氢硅油质量分数为1. 0%, 催化剂质量分数为0. 4%, 缩合反应温度8 0℃, 反应时间2h。 应用红外光谱法比较改性前后破乳剂官能团的特征峰, 分析物质结构所发生的变化, 验证反应获得了目标产物。考 察其对克拉玛依三次采油、 辽河油田老化油、 辽河曙光原油、 大庆原油的破乳脱水性能, 结果表明, 对克拉玛依三次 采油脱水效果最好, 其脱水率达8 7. 5%, 三次采油两相分离明显, 界面清晰。现场用破乳剂、 有机硅改性破乳剂脱出 水电导率分别为49 6 0、 70 1 0μ s / c m。有机硅改性破乳剂脱水效果好于现场用破乳剂。

Abstract: According to the Karamay crude oil emulsion prepared in the laboratory, high efficient silicone modified polyether demulsifier suitable for low temperature application was developed. The appropriate reaction conditions were determined through the single factor experiment as follows: the adding amount of hydrogen silicone oil was 1% of polyether mass, the amount of catalyst was 0.4%, the temperature of condensation reaction was 80 ℃, the time of reaction was 2 h. Infrared spectroscopy was used to compare the characteristic peaks of modified demulsifier groups, analysize changes of demulsifier structure and verify the target product. The dehydration effect on the tertiary oil recovery of Karamay, aging oil of Liaohe Oilfield and crude oil of Liaohe Shuguang and Daqing was studied. The dehydration rate of Karamay tertiary oil recovery was up to 87.5%, and twophase separation of tertiary oil recovery was obvious and clear. Conductance rate of dehydrated water was 4 960μs/cm and 7 010 μs/cm when unmodified demulsifier and silicone modified demulsifier were used. The dewatering effect of silicone modified demulsifier was better than the demulsifier used in site.
