摘要

AbstractOil displacing agents used in oil drilling and extraction can improve crude oil recovery. Acrylamide polymers were the most common oil displacing agents because of their high viscosity and low cost. However, conventional acrylamide polymers were susceptible to hydrolysis and thermal degradation in harsh reservoir conditions. Unique physical and chemical properties of nanoparticles promise to improve the performance of acrylamide polymers in harsh reservoir conditions. In this paper, the nano-micron copolymers of acrylamide (AM), 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS), and modified nano-silica (M-SiO2) were synthesized by two methods: aqueous solution polymerization and inverse emulsion polymerization, named W-PAAGS and E-PAAGS, respectively. The characterization was studied by Fourier transform infrared spectroscopy (FTIR), thermogravimetry (TG), particle size analysis, transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The thickening ability, temperature resistance, salt resistance, and thermal stability of the two polymers synthesized were studied. The results showed that E-PAAGS had a better thickening ability than W-PAAGS. The viscosity of the E-PAAGS solution was much higher than that of the W-PAAGS solution at polymer concentrations above 5000 mg/L. The temperature and salt resistance of E-PAAGS was also better than that of the W-PAAGS. In addition, E-PAAGS exhibits better aging stability. After 30 days of aging, E-PAAGS had 71.3% viscosity retention whereas only 52.7% retention was observed for W-PAAGS, and the viscosity of E-PAAGS was always higher than that of W-PAAGS. The significant difference properties of W-PAAGS and E-PAAGS was due to the differences in copolymer structure caused by the different polymerization methods.Keywords: Aqueous solution polymerizationinverse emulsion polymerizationpolyacrylamide copolymernano-silicaflooding agent AcknowledgmentsWe would like to thanks to the Financial Support of Scientific research and technology development projects of China National Petroleum Corporation Limited (2022ZG06) and the National Natural Science Foundation of China (52274011) for this work.Disclosure statementAll the authors declare that they have no conflict of interest.
