Abstract
In order to meet the demand of high temperature,high pressure and low permeability reservoirs to continue to improve oil recovery,a new nano oil displacement agent NSH-1 was synthesized with acrylamide AM,hyperbranched polymer NHP,polymerizable sulfobetaine SB-1 and nano SiO2 as the main raw materials.The synthetic conditions of NSH-1 were optimized with the viscosity value of the solution as the evaluation index,and the viscosity increasing performance,anti-aging performance and oil displacement performance of NSH-1 were investigated.The results showed that when the initiator dosage was 0.5％,pH value was 7.5,reaction temperature was 55 ℃,and reaction time was 5 h,the viscosity value of NSH-1 was relatively moderate.When its mass fraction was 0.2％,the viscosity could reach 35 mPa·s.The higher the mass fraction of NSH-1,the higher the viscosity value of the solution.It is recommended that the optimal mass fraction be 0.3％.At this point,the viscosity values of NSH-1 solution prepared with distilled water and simulated formation water are 90 mPa·s and 58mPa·s,respectively.NSH-1 has strong temperature resistance and aging resistance.When the aging temperature is 100～150 ℃,the viscosity value is still high after 60 days of aging.The oil displacement effect of NSH-1 is good,and when its injection volume reaches 0.5 PV,it can increase the recovery rate of crude oil in the core by 25.72％.The research results suggest that the new nano oil displacement agent NSH-1 can meet the needs of chemical oil recovery in high temperature,high pressure,and low-permeability reservoirs to improve oil recovery.关键词
