查询词典 water-repellent

The produced water which was made by crude oil dehydration containing polymer, alkaline and surfactant, brought many technique problems in the water treatment process system, this made the polymer flooding and water flooding water treatment technologies difficult to suit to the disposal requirement of the special water. The developed experiment research indicated that: because of the surfactant, the semidiameter of the oil droplets in the ASP flooding is much smaller than that in polymer flooding, and the stability of the oil droplets is higher than that in polymer flooding, The viscosity and combine difficulty of the oil droplets increased, and all the changes of speciality resulted in the increased difficulty in the ASP flooding produced water disposal.

三元复合驱采出液经脱水后得到的采出水中，因含有聚合物、碱和表面活性剂，给采出水处理工艺系统带来了一系列的技术问题，使已经应用于水驱和聚合物驱采出水处理的技术难以适应这种特性的采出水的处理要求，已经开展的实验研究表明：三元复合驱采出水中由于表面活性剂的存在，使采出水中油珠的粒径远远小于聚合物驱采出水，油珠的稳定性明显大于聚合物驱采出水；由于聚合物的存在，采出水粘度增大，使油珠聚并难度增大，这些特性的变化造成三元复合驱含油污水的处理难度大于聚合物驱。
