| 英文摘要 | This paper presents a study of heterogeneous caprock fracturing processes during underground CO2 injection into a brine aquifer. We simulate CO2 injection and fracturing using a combination of the TOUGH2 multiphase flow simulator and the RDCA rock discontinuous cellular automaton code. Our analysis shows that fluid pressure evolution, CO2 saturation, fracture opening, propagation and fracturing path are strongly dependent on the heterogeneity of caprock. The obvious risk that the fracture propagates upwards to provide a new flow path toward shallow ground water aquifers or released to the atmosphere and thereby reducing the efficiency of the CO2 sequestration and potentially contaminating groundwater resources is demonstrated. |
