英文摘要This study investigates the micro-mechanism by which the hydrophobic chain length LHC of alkyl polyglycosides (APGs) affects the stability of CO2 foams, and its influence on the behavior of CO2 sequestration in deep saline aquifers. The results demonstrated that increasing LHC within a specific range (9-11) resulted in enhanced adsorption of APG molecules within the bubble liquid film, augmented binding effect of APG on CO2 and water molecules, and improved cation aggregation at the hydrophilic group of APG, thus strengthening the CO2 foam stability. Nevertheless, further LHC increases weakened the water-solubility of APG, and reduced the aggregation of water molecules and cations around the hydrophilic groups of APG molecules, which weakened the mechanical strength of CO2 foam liquid film and its stability. Low-field nuclear magnetic resonance (NMR) showed that as the LHC increased from 9 to 11, the stability of CO2 foam inside the sandstone core is continuously strengthened, and an ideal piston-like displacement formed. Foam not only improved the CO2 storage space in macro-pores, but also enhanced the entrances and displacements of the internal water in the meso- and micropores, providing more space for CO2 sequestration. However, further LHC increases weakened the CO2 foam stability inside the sandstone core. Although CO2 foam could occupy many macro-pores, its ability to divert to meso- and micro-pores was weakened, and the CO2 storage capacity in sandstone cores was reduced overall.
