Abstract: A method for enhancing geological storage by injecting nanoparticles to stabilize CO2 microbubbles, which belongs to the technical field of multiphase flow. The method first improves the physical properties of the fluid by pre-mixing CO2 and nanoparticles, and then the fluid is transported to the underground through high-pressure pipelines, and then CO2 microbubbles containing nanoparticles are generated through a dense perforated plate arranged by an injection well to improve the dissolution rate and sweep efficiency of the gas in the saline aquifer, so as to enhance the later mixing of the fluid. The combined injection can improve CO2 storage capacity and storage safety, and further reduce the risk of gas leakage in the reservoir.
