摘要
Abstract
With potassium persulfate/sodium bisulfite as a redox initiator system,an amphiphilic copolymer SL-1 with surface activity was synthesized from acrylamide and surface active monomer (YS) with pendant groups including sulfonic group,ester group and long-chain alkyl group,etc.by free radical solution copolymerization,and was characterized by means of FTIR.The influence of polymer concentration on the interfacial tension between SL-1 and Daqing crude oil was investigated.The results show that the interfacial tension decreases to minimum of 7.84 mN/m with increasing the polymer concentration.Factors affecting the stability of the emulsion formed by Daqing crude oil and SL-1 solution were studied.The results show that the emulsion with 1 500 mg/L SL-1 solution,which contains 2.0% (x) YS,has good stability when it is applied in the oil reservoir with temperature of lower than 80 ℃ and salinity of about 5 000-25 000 mg/L.关键词
