Effects of formation dip angle and salinity on the safety of CO2 geological storage - A case study of Shiqianfeng strata with low porosity and low permeability in the Ordos Basin, China

The safety of CO2 geological storage is a key problem that hinders its implementation. In particular, the formation dip angle and salinity can directly affect the spatial migration distribution, storage form and storage amount of CO2. A three-dimensional simulation model was established to evaluate the effects of the formation dip angle and salinity on the safety of CO2 geological storage. The simulation results showed that a larger dip angle...
