Synthesis and Properties of Poly(AM-AA-DNDA-DMDAAC) as an Oil-Displacing Agent
摘要
Abstract
A novel water-soluble copolymer(PMADD) was synthesized from acrylamide(AM),acrylic acid(AA),N,N-diallyl oleic-amide(DNDA) and diallyl dimethyl ammonium chloride(DMDAAC), and characterized by means of FTIR and rheology. The properties of PMADD for enhanced oil recovery were studied. The results indicated that the optimum conditions for the synthesis of PMADD were:m(AM)∶m(AA)∶m(DMDAAC)∶m(DNDA) 5∶5∶0.3∶0.04,45℃,reaction system pH 7 and initiator dosage 0.3%(w)(based on the mass of the reactants). When the PMADD concentration was 2 000 mg/L,the apparent viscosity of its solution was 590.3 mPa·s. The viscosity retention rate of PMADD was 7.0% at the shear rate of 1 000 s-1. When the NaCl concentration was 12 000 mg/L,the viscosity retention rate of PMADD was 21.7%. The enhanced oil recovery(EOR) could increase by 12.46% when the concentration of PMADD was 2 000 mg/L and the salinity of simulated formation water was 5 200 mg/L.关键词
