CO₂ geological sequestration serves as a foundational technology for low-carbon fossil energy utilization and a critical pathway for achieving carbon neutrality objectives globally. This study pioneers a thermo-hydro-mechanical-chemical (THMC) numerical model incorporating heterogeneous permeability distributions and time-dependent rock mechanical properties, specifically tailored for deep saline aquifers in the Xinjiang Tarim Basin. A decade-long simulation was conducted to evaluate the impacts of injection strategies on reservoir storage capacity and geomechanical stability.
