In order to simulate the seismic responses of caverns with different lateral scale in carbonate reservoirs,we designed cavern geologic models with same height and fillings but different lateral scale,adopted numerical simulation and physical modeling for forward simulation,and analyzed the variation features of seismic responses via the changes of cave width.
