摘要
以亲水性丙烯酰胺(AM)为单体,N,N-亚甲基双丙烯酰胺(MBA)为交联剂,氢氧化钠(NaOH)/亚硫酸氢钠(NaHSO_3)为引发剂,失水山梨醇单油酸酯(Span80)/失水山梨醇单油酸酯聚氧乙烯醚(Tween80)/烷基酚聚氧乙烯醚(Tx-10)为乳化体系,在白油中进行反相乳液聚合,制备了改性聚丙烯酰胺微球(PAM)。采用红外光谱、粒径分析和动态流变仪等方式对该微球进行了表征。结果表明聚丙烯酰胺微球已聚合且性能良好,在水中溶胀5 d后,粒径增大至1μm,乳液能迅速分散在水中,且黏度低、耐剪切,可以被顺利注入到地层深部。将此微球在长庆油田进行现场应用,结果显示试验井均出现不同程度的增油,说明此微球在调剖堵水方面具有良好的效果。
Modified polyacrylamide microspheres（ PAM） was prepared by using hydrophilic acrylamide（AM） as monomer,N,N-methylenebisacrylamide（MBA） as crosslinking agent,Sodium hydroxide（NaOH）/Sodium bisulfite（NaHSO_3） as Initiator and Sorbitan monooleate（Span80）/Sorbitan monooleate polyoxyethylene ether（Tween80）/Alkyl phenol ethoxylates（Tx-10） as emulsifying system in white oil with inversing emulsion polymerizetion as method.Fourier transform infrared spectroscopy（FTIR）,particle size and Dynamic Rheometer analysis were used to characterize the microspheres.The results show that modified polyacrylamide microspheres have been successfully synthesized and have good performance.5 days after swelling in water,the particle size increased to 1μm,emulsion rapidly dispersed in water,low shear viscosity,shear resistance,can be successfully injected into deep formations.It was applied in Changqing oilfield,and the test wells performed different degrees of increasing oil.This microspheres reflected good results in terms of profile control water plugging.
