The utility model discloses a device for evaluating gravel packing effect, which comprises packing particles, a temperature measuring screen pipe and a pump prying device, the temperature measuring screen pipe comprises a thermodetector and a screen pipe base pipe, the thermodetector is mounted on the screen pipe base pipe, the pump prying device is used for conveying the packing particles and sand-carrying fluid to a target area, and the packing particles are filled with the sand-carrying fluid. The filling particles are used for flowing under the action of the sand-carrying fluid, filling the whole target area and heating after filling the whole target area, the thermodetector is used for measuring the temperature of the target area after heating of the filling particles and forming a temperature change curve, and the gravel filling effect is evaluated according to the comparison result of the temperature change curve and the theoretical rising temperature T. The theoretical rising temperature T refers to t
