Abstract: To decrease fluid emulsification and system scale caused by NaOH/surfactant/polymer flooding, a pilot test of Na 2 CO 3 /surfactant/polymer flooding was developed in Daqing Oilfield. The results show that the two problems mentioned above were controlled, but scale in the injecting system is becoming a new technical problem and the scale aggravates reservoir heterogeneity. By analyzing the scaling mechanism and the properties of the profile control agent, the study presents technique of Cr 3C polymer gel for im… Show more
