Totally 6 cases（Case 0-5）with various WAG schemes were investigated with numerical simulations.the total injection amount of CO2 is 1MMt and varies with water.Table 5 lists the injection shut in timetable of Case 0-4.The injection rate maintains constant at 1.1325 kg/s without any water injected，this injection scheme is applied in Case 0 as well.Case 1 is set as a reference example with hysteric capillary pressure and relative permeability.The simulation case with non-hysteric capillary pressure and relative permeability is referred to as Case 0.The shut-in and timetable of CO2 and water injection of Case2-4 is the same，though the water injection rates are different in order to exam the effects of amounts of injected water.Case 5 is set up to test the effect of shut-in and restart frequency，the total injection period is 8 month，spited evenly into 42-month period，and separated by 3 shut-in period of 4/3 month each with water injection rate 0.25kg/s.Fig.15 demonstrates these timetables.
