摘要
为了准确分析油田采出液中聚合物的含量分布及变化,采用高效液相色谱法建立了检测油田采出液中聚合物含量的方法。采用适宜的聚合物试样作为标准物,建立了对应的定量工作曲线;对油田采出液中的聚合物进行分离提纯,建立准确合理的提取工艺,并对聚合物的含量进行分析检测。实验结果表明,该提取工艺获得的聚合物组分的纯度高于95%,可以作为定量标准物;以该聚合物组分为定量标准物时的测定结果,与以相对分子质量为2 500×104的聚丙烯酰胺为定量标准物的测定结果相比,偏差为20%。
Liquid chromatogr aphic detection technology was adopted to analyze the concentration and variation tendency of polymers in oilfield produced liquid.To establish the corresponding quantitative working curve,appropriate polymer samples were required to act as quantitative standard substances during the development of the detection method.Polymers in the oilfield produced liquid were separated and purified,and an accurate and reasonable extraction process was established.In addition,the concentration of the polymers in the oilfield produced liquid was determined.The results showed that obtained polymer samples had high purity over 95% and could be used as quantitative standard substances.With the above polymer component as quantitative standard substances,the determination results had a deviation of about 20% as compared to that of with polyacrylamide（relative molecular mass 2 500×104） as quantitative standard substances.
