聚合物驱采出污水有效回注方法探讨

Discussion on Effective Reinjection Method of Polymer Flooding Wastewater

通过室内实验研究金属铁锈对聚合物黏度的影响、污水中二价铁离子对聚合物黏度的影响、污水中三价铁离子对聚合物黏度的影响,通过在采出污水中加入污水处理剂、曝氧、加入一定比例清水的方式,能够提高采出污水配置或者稀释聚合物溶液的黏度。进行聚合物溶液的合理配置,实现采出污水有效回注,是降低环境污染的有效方法。

Through the indoor experimental study of metal rust,two valent iron ion and ferric iron impacts on polymer viscosity in wastewater,adding wastewater treatment agent,oxygen exposure,adding a certain proportion of clean water could improve the quality of wastewater or dilute the viscosity of polymer solution.It is the best way to reduce the environmental pollution by rational configuration of polymer solution and effective reinjection of wastewater.
