AI Technical Summary
Existing technologies fail to accurately characterize the real-time coupling relationship between the surface, wellbore, and reservoir, leading to inaccurate evaluation of the energy storage performance of compressed gas geological energy storage systems. In particular, wellbore transport and porous reservoir flow have a significant impact on energy storage performance under deep geothermal conditions.
By constructing a surface-wellbore-reservoir coupled model and using iterative calculation methods, a real-time feedback relationship is established in the energy storage and release process, including a surface thermodynamic model, a wellbore model, and a reservoir model. The model considers the wellbore gravity effect, the reservoir buoyancy effect, and multiphase flow to achieve full-process coupling.
Accurately simulate the state changes of energy storage working fluid, improve the accuracy of energy storage efficiency and scale evaluation, reduce the amount of calculation caused by temperature and pressure fluctuations, and improve the accuracy of energy storage performance evaluation.
