改性石墨烯量子点聚表剂的制备及性能评价
Preparation and performance evaluation of modified graphene quantum dots polymeric surfactant
摘要
Abstract
To address the limitations of low molecular weight polymers in low permeability reservoirs,such as large molecular size and poor temperature or salt resistance,a novel modified graphene quantum dots(GQDs)polymeric surfactant GQDs-PSBMA was synthesized by sulfobetaine monomer(SBMA).GQDs-PSBMA was characterized by FTTR and a laser particle size analysis.The interfacial tension reduction,thermal stability,salt resistance,shear stability,and rheological properties of GQDs-PSBMA solution were subsequently investigated.Experimental results indicate that GQDs-PSBMA exhibits a minimum interfacial tension at 0.10%(w)and 90℃,and retains viscosity retention rate of 81.30%after 90 d of sealed storage.Moreover,the viscosity retention rate of GQDs-PSBMA solution reaches 60.39%in a brine with NaCl concentration of 10 000 mg/L.Upon subjecting GQDs-PSBMA solution to shearing for varying durations of 1,3,5 s,the lowest viscosity retention rate observed is 77.5%.GQDs-PSBMA demonstrates excellent temperature,salt,and shear resistance.关键词
