摘要：

研究了锂皂石颗粒对模拟聚合物驱采出水乳化稳定性能和油水界面性质的影响。通过分析含油量表征分析了锂皂石颗粒对聚合物驱采出水乳化稳定性的影响,发现在HPAM质量浓度为100～600mg／L、锂皂石颗粒质量浓度为50～100mg／L时,对聚合物驱采出水稳定性影响最大。研究了锂皂石颗粒对模拟聚驱采出水中油滴Zeta电位、油水界面张力、颗粒油滴聚集状态及乳化体系黏度的影响。结果表明:在实验浓度下,随锂皂石颗粒质量浓度增大,Zeta电位下降、界面张力降低、体系黏度提高,对采油污水稳定性影响显著;当锂皂石颗粒质量浓度大于100mg／L后,聚驱采出水稳定性减弱,此时有利于聚合物驱采出水的处理。

Abstract:

The effects of hectorite particles on oilwater separation and oilwater interfacial properties of polymer flooding produced water were investigated. The stability of the polymer flooding was characterized by oil content analysis. When the HPAM(hydrolyzed polyacrylamide) concentration was 100-600 mg/L and the hectorite particles concentration was 50-100mg／L, and the hectorite particles had the greatest impact on the stability of the polymer flooding produced water under the experimental conditions. The influences of hectorite particles on Zeta potential, interfacial tension, oilmineral aggregates of polymer flooding produced water and viscosity were studied. The results showed that the addition of hectorite particles could cause the Zeta potential of oil droplets to rapidly decrease, the interfacial tension declined and viscosity was enhanced in polymer flooding produced water. The effect of hectorite particles on emulsification stability of polymer flooding produced water was noticeable. When the hectorite particles concentration was higher than 100mg／L, the oil droplets tended to coagulate, which was of benefit to the polymer flooding produced water treatment.

Key words: polymer flooding produced water, oil content, interfacial properties, interfacial tension, Zeta potential, viscosity
