化学添加剂对聚合物中氧的影响及作用机理

Impact of chemical additives on the oxygen in polymer and its function mechanism

在大庆油田利用暴氧污水配制聚合物溶液有效地解决了污水排放问题,但这也引起了有关氧对聚合物溶液性质影响的争论。应用实验对比方法,研究了脱氧剂、杀菌剂和稳定剂对聚合物溶液性质的影响,探讨了化学驱油剂性质对氧影响的作用机理。实验结果表明,脱氧剂、杀菌剂和稳定剂的加入将有利于提高化学驱油剂粘度的稳定性,改善化学驱油效果。

In Daqing Oilfield,using the sewage full of oxygen to prepare the polymer solution has already resolved the problem of the sewage drainge effectively,but it also caused the dispute about the influence of the oxygen on the polymer solution property.Using the method of ex-perimental correlation to study the impact of deoxidi-zer,bactericide and stablizer on the polymer solution property,and to explore the function mechanism of im-pact of chemical oil displacement agent on the oxygen. The experimental results show that the adding of the deoxidizer,bactericide and stablizer will help to im-prove the stability of the viscosity of the chemical oil displacement agent,and then improve the effect of chemical flooding.
