【 摘 要 】

An analysis of the influence of injection well location on CO₂ storage efficiency was carried out for three well-known geological structures (traps) in deep aquifers of the Lower Jurassic Polish Lowlands. Geological models of the structures were used to simulate CO₂ injection at fifty different injection well locations. A computer simulation showed that the dynamic CO₂ storage capacity varies depending on the injection well location. It was found that the CO₂ storage efficiency for structures with good reservoir properties increases with increasing distance of the injection well from the top of the structure and with increasing depth difference to the top of the structure. The opposite is true for a structure with poor reservoir properties. As the quality of the petrophysical reservoir parameters (porosity and permeability) improves, the location of the injection well becomes more important when assessing the CO₂ storage efficiency. Maps of dynamic CO₂ storage capacity and CO₂ storage efficiency are interesting tools to determine the best location of a carbon dioxide injection well in terms of gas storage capacity.
