Abstract The high-temperature foam system was constructed by alkylamine modified nano-laponite, and its temperature-resistant and salt-resistant performance was evaluated. The steam profile control and flooding performance of the high-temperature foam system was evaluated by heterogeneous sandpack flooding tests. The results of infrared spectrum characterization and contact angle measurement show that the wettability of nano-laponite is changed from strong hydrophilic to weak hydrophilic by adsorbing alkylamine on the surface of nano-laponite, so that the modified nano-laponite can be adsorbed on the gas-liquid interface to form a solid particle interfacial film, which enhances the rigid strength of liquid film and improves the foam stability. The foam stability stabilized by alkylamine-modified nano-laponite can be greatly improved. The half-life of foam can be increased to 275 min by addition of 1.0% modified nano-laponite, and it has good temperature and salt resistance, which can maintain good foam stability at 250 ℃ and 40 000 mg/L salinity. The modified nano-laponite enhanced foam system has excellent profile control and flooding performance for high-temperature steam, and the resistance factor can reach more than 30 at 250 ℃. The modified nano-laponite enhanced foam system can effectively adjust the profile of steam injection, which resulting in increase of the sweep efficiency of steam flooding, and thus greatly improving the oil recovery of steam flooding in the heterogeneous formations.
