摘　　要：选用两种阳离子有机絮凝剂与三种非离子改性聚醚类破乳剂复配,以提高聚合物驱采出液的脱水效果.进行了室内和现场脱水试验,考察了絮凝剂与破乳剂之间的协同作用,并对药剂的作用机理进行了探讨.室内实验结果表明,阳离子有机絮凝剂能显著提高脱水量和脱水速度,并改善脱出水颜色,拥有较低分子量但高阳离子度的LWL效果更好,两种絮凝剂复配使用也可获得较好效果.现场试验表明,YD-09复合药剂能够在不改变目前工艺设施的条件下实现原油的稳定达标外输.Two cationic organic flocculants and three modified Pluronic demulsifers were selected together to enhance the dehydration efficiency of polymer flooding produced fluid. Dehydration experiments were put forward in lab and on the spot to exam the cooperation effect between flocculants and demulsifiers. The mechanism of cooperation effect was also discussed. The results indicate that cationic flocculants can improve both volume and speed of the dehydration, and can make the water separated from oil clearer. LWL, which has smaller molecule weight and stronger cationicity, has a better performance in dehydration with the cooperation of demulsifiers. The mixture of LWL and BWJ also performs well. YD-09 can make the output oil fit the oilfield standard without changing the current technics and establishments.
