污水稀释聚合物溶液驱油方法

Method of displacement with polymer solution diluted with produced water

针对油田采出污水外排的问题,开展了污水稀释聚合物驱油研究。结果表明,污水暴氧、提高聚合物浓度及采用超高分子聚合物,可有效提高污水聚合物溶液的粘度,是保证污水注聚的有效手段。这一研究成果应用于聚驱现场试验,取得了良好的试验效果。

Aiming at the problem of produced water drainage of oil fields, this paper performs a study on displacement with polymer solution diluted with produced water. The result shows that aerobic produced water, increasing polymer concentration and using high molecular weight polymer can increase the viscosity of polymer solution with produced water. This achievement is used in a pilot test and has a good effect.
