大庆油田三元复合驱采出水的稳定性及其反相破乳剂的应用

Stability and Chemical Treatment of Daqing Oilfield ASP Flooding Produced Water

采用室内配制的模拟三元 (碱、表面活性剂、聚合物 )复合驱采出水研究了残留驱油剂含量对大庆油田三元复合驱采出水稳定性的影响规律 ,以模拟采出水为介质研制了一种针对大庆油田三元复合驱采出水的反相破乳剂FM - 3 ,FM - 3对北 1- 6 -P36井实际三元复合驱采出水 4h除油率 93 5 %。

The influence of residual alkali,surfactant and polymer on the stability of ASP (alkali,surfactant and polymer) flooding produced water was studied on artificial ASP flooding produced water.Using artificial ASP flooding produced water a reverse emulsion demulsifier was developed for ASP produced water treatment.The oil water separation performance of the reverse emulsion demulsifier was tested on both artificial ASP produced water and oilfield ASP produced water.
