Experimental study on mineralization storage mechanism of CO_2 in saline aquifers of Nanpu depression

In order to explore the short term changes of rock and fluid in saline aquifers after the CO2 injection,the interaction process between CO2-saturated rocks and saline water was simulated in detail through the self designed autoclave experiment carried out under the simulated reservoir conditions(109℃and 33.1MPa).The feasibility of CO2 mineralization storage was proved and the mineral corrosion,precipitation and changes in solution and its reason...
