The invention relates to a method for monitoring injected polymer propellant front simulation, and belongs to the technical field of crude oil recovery. The method comprises the following steps: firstly, collecting polymer solution concentration values on sampling points of an experimental model; aiming at the polymer solution concentration values on various sampling points, predicting polymer concentration values of the other parts of the model by a kriging interpolation algorithm; and achieving monitoring of polymer propellant front simulation according to the predicted polymer concentration values of the other parts of the model. By a mathematical geology method, linear unbiased estimation and minimum variance estimation are carried out on a region by a kriging interpolation method according to the concentration values of a plurality of information samples inside and outside the region, so that monitoring of the injected polymer propellant front simulation of the overall region is achieved; and the method can be applicable to monitoring of the injected polymer propellant front simulation.
