Abstract

Abstract

Geological storage is one of the most effective means to reduce the anthropogenic greenhouse gas emissions to mitigate the worsening global warming. Depleted oil-gas reservoirs, coal seams and deep saline aquifers are potential sites for CO₂ geological storage of which saline aquifer has the greatest potential for sequestration. Among the many effective mechanisms, dissolving storage is characterized by large storage capacity, long action time and high safety. When evaluating the storage capacity of a deep saline aquifer, CO₂ solubility becomes a key parameter. In this paper, an experimental method is proposed and used to measure the CO₂ solubility in Shanxi Formation water. Ordos Basin is an important energy base for China which releases a lot of high concentration CO₂. Studies show CO₂ geological storage is possible in Ordos Basin since its Shanxi Formation forms many source-reservoir-cap assemblages, and it is of great importance both in theory and practice to probe into CO₂ solubility in Shanxi Formation water of Ordos Basin. In this paper, chemical composition of Shanxi Formation water collected from the Ordos Basin were analyzed. CO₂ solubilities in the artificial synthetic Shanxi Formation waterwere measured at 40-80℃, 8-12 MPa pressure. The results can be used for the evaluation of the CO₂ storage capacity in deep saline aquifer of Ordos Basin.
