The invention specifically provides a compressed packer rubber barrel with a spacer ring combined spring shoulder pad. the compressed packer rubber barrel is characterized in that a rubber barrel body comprises two side rubber barrels, and a medium rubber barrel positioned between the two side rubber barrels; two ends of the medium rubber barrels are respectively separated and in close contact with the side rubber barrels through a spacer ring; multi-layer circular spiral spring rings are respectively arranged at the shoulder parts of the two side rubber barrels and used for being radially expanded along the rubber barrel body to protect the shoulder parts of the side rubber barrels when an opposite axial extruding force is applied to the rubber barrel body. According to the compressed packer rubber barrel with the spacer ring combined spring shoulder pad, the multi-layer spiral springs can effectively protect the shoulder parts of the rubber barrel body; when in setting packing, the multi-layer spiral spring is expanded to block an a ring space to prevent the rubber barrels from being extruded; the multi-layer spiral spring is retracted under the tension force of the spring when releasing the packing and recovering; therefore, the problem of difficult retracting of the general rubber barrels can be avoided; in case that one section is failed in sealing when the rubber barrel body works, the other two sections can perform effective sealing; the compressed packer rubber barrel is high in bearing capacity and deformation resistance, and cam meet the requirements on high temperature, high pressure, and releasing and recovering.
