AI Technical Summary
Existing technologies for assessing the safety of scCO2 geological storage suffer from several problems, including reliance on a single information source, fixed safety thresholds that fail to consider the degradation of mechanical parameters caused by dissolution, and a lack of physical constraints in purely data-driven methods. These issues make it difficult to accurately identify and provide early warnings of the safety status of geological storage.
A multimodal safety assessment system is adopted, which combines numerical simulation, multi-source monitoring data, cross-modal attention feature fusion and physical constraints to construct multi-channel simulation images and time series. Through the self-attention mechanism, long-term time dependence and potential leakage precursors are captured, and the impact of CO2 dissolution on reservoir mechanical parameters is quantified to achieve accurate identification and early warning of safety status.
It enables accurate identification and early warning of the safety status of scCO2 geological storage, and is applicable to safety monitoring and risk assessment of geological storage projects in deep saline aquifers, depleted oil and gas reservoirs and coal seams, providing engineering decision support.
