Abstract: The effects of nanoparticle charge and type on foam stability and plugging performance were systematically investigated. The results indicated that positively and negatively charged silica sols had no significant influence on the foaming ability or foam stability of the foaming agent. In contrast, silica-alumina sol significantly enhanced the foaming performance, increasing foaming ability by 41.8% and foam stability by 103%. The optimal mass fraction was determined to be 1% through optimization experiments. After aging at 300 °C, the foam stability of the nanocomposite foaming system did not exhibit a significant decrease, indicating its suitability for high-temperature reservoir conditions.
