description The invention relates to a simulation system for a pressure-back method test. The simulation system specifically comprises a wellbore simulation device, a formation simulation device and a control andsignal processing device, wherein the wellbore simulation device comprises a pressure-bearing casing pipe string, a wellhead connecting device, a bottom connecting device and a plurality of flow parameter monitoring sensors; the formation simulation device comprises a formation fracturing simulation device, a fluid pressure-back channel, a wellhead flow-dividing device and a ground collection device, the formation fracturing simulation device is placed in an artificial well bottom on the lower portion of the wellbore simulation device and connected with the pressure-bearing casing pipe stringthrough the bottom connecting device of the wellbore simulation device, an annular space between the pressure-bearing casing pipe string of the wellbore simulation device and an outer layer casing pipe serves as the fluid pre
