针对渤海锦州9-3油田聚合物驱生产污水组成特点,分别测定了不同相对分子质量、质量浓度及水解度的产出聚合物对含聚污水表观黏度、油滴粒径、Zeta电位、油水动态界面张力、油水平衡界面张力、油水界面扩张黏弹性等指标的影响。研究结果表明,含聚污水中产出聚合物的存在会增加含聚污水的黏度,吸附于油水界面增强含聚污水中O/W型乳液滴的Zeta电位,增加水化层以及油水界面膜强度,从而增强污水的乳化程度和稳定性,降低污水中油滴的聚并效率,增大了含聚污水的达标处理难度。
針對渤海錦州9-3油田聚閤物驅生產汙水組成特點,分彆測定瞭不同相對分子質量、質量濃度及水解度的產齣聚閤物對含聚汙水錶觀黏度、油滴粒徑、Zeta電位、油水動態界麵張力、油水平衡界麵張力、油水界麵擴張黏彈性等指標的影響。研究結果錶明,含聚汙水中產齣聚閤物的存在會增加含聚汙水的黏度,吸附于油水界麵增彊含聚汙水中O/W型乳液滴的Zeta電位,增加水化層以及油水界麵膜彊度,從而增彊汙水的乳化程度和穩定性,降低汙水中油滴的聚併效率,增大瞭含聚汙水的達標處理難度。

According to the composition of wastewater produced from polymer flooding in Bo-hai JZ9-3 Oilfield ,influences of produced polymers with different molecular weight ,concentra-tion and hydrolytic degree on the apparent viscosity ,particle sizes of oil droplets ,Zeta potential , dynamic interfacial tension ,equalize interfacial tension and interfacial dilatational properties were measured .The results indicated that the produced polymer with low molecular weight could im-prove the apparent viscosity of wastewater ,and the Zeta potential of O/W emulsion and the oil-water interfacial film strength were increased after adsorption of polymer in oil-water contact . Consequently the wastewater emulsion stability was increased ,and the coalescence efficiency of oil droplets in wastewater was decreased greatly ,so that the difficulty of polymer-contained sew-age reaching standard became harder .
