| 英文摘要 | Saline aquifer, a geological body, is widely distributed in the world and has high CO 2 sequestration potential. Due to the large differences in viscosity and density between the CO 2 and brine and the micro -heterogeneity of the saline aquifer, CO 2 override, and viscous fingering may occur in strata, resulting in low CO 2 sequestration efficiency. Following the concept of green chemistry, this study formulated CO 2 foam using biopolysaccharides and a green surfactant alkyl polyglycosides (APG), to enhance the CO 2 sequestration efficiency in saline aquifers. The ability of three biopolysaccharides (diutan gum, welan gum and xanthan gum) to stabilize CO 2 foam was explored. According to the foam drainage activation energy and the Ostwald ripening rate, the CO 2 foam with diutan gum as the stabilizer and APG as the foaming agent exhibited the favorable performance. The mechanism of diutan gum stabilizing CO 2 foam was analyzed through studies on intermolecular interactions, interfacial properties, rheology, and micromorphology studies. We then investigated the effects of foam quality and flow rate on the CO 2 foam rheology in sandstone cores by analyzing the changes in CO 2 saturation, the matching relationship between bubble diameters under different conditions and sandstone core pore size, and the variation in foam rheology was explained. Furthermore, the ability of CO 2 foam to enhance CO 2 sequestration was explored in saline aquifers using core -nuclear magnetic resonance techniques. CO 2 foam largely reduces the water saturation of macropores and establishes high -seepage resistance to facilitate CO 2 foam diversion to the meso- and micropores. This fully leverages the space in these pores to store CO 2 and greatly improves CO 2 sequestration in saline aquifers. |
