Abstract
To solve the problem of heavy oil demulsification difficulties in Liaohe Oilfield, phenolamine resin initiator was synthesized from p-trifluoromethyl phenol, and then FB series fluorinated polyether demulsifiers were synthesized by block polymerization using ethylene oxide (EO) and propylene oxide (PO) as raw materials. The demulsifiers were characterized by infrared spectroscopy, cloud point, hydrophilic-lipophilic balance (HLB) value, and surface tension. The demulsifying and dehydrating properties were tested by demulsifying and dehydrating experiments, the demulsification mechanism was analyzed by the microscopic demulsification process test, and the influence of demulsifier addition and demulsifying temperature on demulsifying performance was also studied. The results showed that under the condition of the optimum demulsification temperature of 60 °C and the optimum demulsifier dosage of 100 mg/L, the water removal (%) of fluorinated polyether demulsifier of FB 4 was the highest, and the overall water removal (%) of 50 mL crude oil emulsion in Liaohe Oilfield reached 90.33% within 2 h, which was better than the current demulsifier used in Liaohe crude oil.

Abstract
The application of chemical flooding improves the stability of the produced emulsion, which reduces the demulsification efficiency of conventional demulsifiers. To improve the demulsification effect, in this paper, a new multibranched nonanionic polyether demulsifier, FYJP, was prepared by grafting carboxylate based on a nonionic demulsifier. The FYJP demulsifier could generate an initiator through p-tert-butylphenol, triethylenetetramine, and methanol, which was polymerized with ethylene oxide (EO) and propylene oxide (PO) to produce a nonionic polyether demulsifier. Sodium chloroacetate was used to modify the polyether demulsifier to obtain a new type of nonanionic polyether demulsifier. The FYJP polyether demulsifier was characterized by the hydrophilic-lipophilic balance (HLB) value, relative solubility (RSN), and surface activity of the demulsifier, and the demulsification mechanism was analyzed by a microscopic demulsification process test, and the effect of demulsifier dosage on the demulsification effect was discussed. Meanwhile, a dehydration test was carried out. The experimental results showed that the highest dehydration rate of the demulsifier was 94.7% at 85 °C, 100 ppm demulsifier dosage, 50 mL of a W/O emulsion, and 120 min demulsification time. The abovementioned studies show that FYJP is an effective demulsifier for chemical flooding emulsions, and this work promises to provide a reference for future demulsifier research.
