摘要:

通过分析油田聚合物驱产出水处理后聚合物的分子特性以及各组分变化,认为含聚合物污水对油层的主要影响因素是污水中聚合物的含量。由岩心驱替实验结果证明,聚合物浓度不同的污水对具不同渗透率油层的适应性是不同的。建议对不同类型油层的注入水选择适合的聚合物浓度。这一研究成果对聚合物驱后的污水利用以及研究注入油层的水质标准具有可参考的意义。

Abstract:

Through analyzing the molecular properties of polymer and component changes after disposal of polymer-bearing sewage produced by polymer flooding, it is considered that polymer concentration is a key factor to lower the permeability of reservoir. The results from the core displacement test show that the adaptability of reservoir with different permeabilities for the polymer-bearing sewage with different polymer concentrations is different. It is proposed to choose suitable polymer concentration for different types of injection water. The research result has a significant reference for utilizing this kind of sewage water and studying the standard of injection water after polymer-flooding.

Key words: polymer-bearing sewage, polymer flooding, molecular property, polymer concentration
