AI Technical Summary
Existing technologies are insufficient to accurately assess the carbon sequestration reserves in deep saline aquifers. Traditional methods cannot effectively reflect the spatial distribution and heterogeneity of lithofacies and geological properties, resulting in high uncertainty in assessment results.
A three-dimensional geological model was used to calculate the carbon sequestration of deep saline aquifers by constructing a stratigraphic potential field, modeling lithofacies under strata-controlled constraints, and modeling geological properties in situ under facies-controlled constraints, combined with the volumetric method.
It improves the accuracy and reliability of carbon sequestration assessment in deep saline aquifers, accurately reflects the spatial distribution of lithofacies and porosity, and provides reasonable suggestions for carbon sequestration site selection.
