Hydrolyzed polyacrylamide (HPAM) is commonly used in polymer flooding, however, it is prone to viscosity reduction at high temperatures and high salinities, weakening its ability to improve oil recovery. In this work, sulfonated modified silicon quantum dots (S-SiQDs) were synthesized and then added to HPAM to study the improvement of rheological properties and enhanced oil recovery performance of HPAM at high temperatures and salinities. It is found that the S-SiQDs with a concentration of only 0.1 wt % can significantly increase the viscosity of HPAM from 28.5 to 39.6 mPa•s at 60 °C and 10,000 mg/L NaCl. Meanwhile, the HPAM/S-SiQDs hybrid solution always possessed higher viscosity and viscoelastic moduli than HPAM, attributed to the hydrogen bonding between HPAM and S-SiQDs. Notably, HPAM/S-SiQDs still maintained elastic behavior at harsh conditions, indicating that they formed a strong network structure. Through oil displacement experiments, it was found that the oil recovery of HPAM/S-SiQDs was higher (28.3%), while that of HPAM was only 17.2%. Thereafter, the utilization sequence of oil during the displacement process was studied with nuclear magnetic resonance experiments. Ultimately, the oil displacement mechanism of HPAM/S-SiQDs was deeply analyzed, including viscosity thickening and wetting reversal.

“…To alleviate the problems mentioned above, it is of vital importance to conduct profile control and water plugging for a low-permeability reservoir. Peer researchers have also studied a large number of chemical agents applied to profile control and enhanced oil recovery, such as linked polymer solution, precross-linked particles, weak gel, colloidal dispersion gels, inorganic particles, − etc. Nevertheless, the gel particles primarily impede the layers close to injectors and are difficult to manage in their migration, which probably causes near-well plugging .…”

Polymer nanospheres are commonly used in scientific and industrial fields including petroleum, electronics, and biomedicine. The precise synthesis of polymer nanospheres with a controllable size and regular shape is important for achieving thermal stability and mechanical properties, which will directly affect the oil displacement effect. In this paper, amphoteric CP(AM-AMPS-DMDAAC) nanospheres with a small particle size and regular shape were prepared by using an acrylamide (AM), 2-acrylamide-2methylpropanesulfonic acid (AMPS), diallyl dimethylammonium chloride (DMDAAC), and methylene-bis-acrylamide mixed solution as the aqueous phase and Span-80 and Tween-80 as the composite emulsifier, followed by reverse-phase microemulsion polymerization. The results showed that nanospheres had temperature and salt resistance and excellent physical and chemical properties. The thermal decomposition temperature was 236.5 °C, the median size of the particles was close to 50 nm, the swelling factor remained at 6.1 nm/nm after water absorption and expansion in the formation water at 120 °C for 7 days, and the swelling factor was 10.4 nm/nm after 14 days. In addition, nanospheres also exhibit good viscoelasticity and pseudoplasticity. The average plugging rate was 79.5% in the low permeability cores, and after the injection of the CP(AM-AMPS-DMDAAC) nanospheres based on water flooding, the average enhanced recovery rate was 13.46%.
