用界面张力仪、表面粘弹性仪和Zeta电位仪测定了胜利坨一原油模拟油与采出水间的界面特性,并研究了聚合物3530S浓度对这些界面特性及乳状液稳定性的影响。结果表明,由于采出水中含有固体悬浮物,使得过滤后采出水与原油模拟油间的界面张力和界面剪切粘度降低;模拟水中加入聚合物后,模拟水与原油模拟油间的界面张力和界面剪切粘度及油滴表面的Zeta电位绝对值均增大,原油与含聚合物溶液的模拟水间所形成的W/O乳状液稳定性随聚合物浓度增加先增强后减弱,存在一个使乳状液最稳定的聚合物浓度。 The interfacial properties between the oil and the produced water in Shengli Tuo-Tuo Oilfield were measured by means of interfacial tension meter, surface viscoelasticity analyzer and Zeta potential meter. The effects of polymer 3530S concentration on these interfacial properties and emulsion stability were also studied. The results show that the interfacial tension and the interfacial shear viscosity of the produced water and the crude oil after filtration are reduced because of the suspended solids contained in the produced water. After adding the polymer into the simulated water, the interfacial tension between the simulated water and the simulated oil The shear viscosity of the interface and the absolute value of the Zeta potential of the droplet surface both increase. The stability of the W / O emulsion formed by the crude oil and the simulated water containing the polymer solution first increases and then decreases with the increase of the polymer concentration, Emulsion The most stable polymer concentration.
