近年来,聚合物驱油技术在胜利油田孤东采油厂得到广泛应用,取得了显著的增油降水效果。但承担含聚污水处理的东二联合站污水处理效果较差,含有PAM的污水黏度大、水中油滴及固体悬浮物在PAM及其水解产物的作用下乳化稳定性强,处理起来非常困难,回注水含油量
In recent years, polymer flooding technology has been widely used in the Gudong Oil Production Plant in Shengli Oilfield, and has achieved remarkable oil precipitation effect. However, the sewage treatment undertaken by East Second United Station, which contains poly-sewerage treatment, has poor effluent treatment effect. The sewage sludge containing PAM has large viscosity. The oil droplets and solid suspended solids in the water have strong emulsification stability under the action of PAM and its hydrolyzate and are very difficult to be handled. Return water content
