A slip sealing structure comprises a cylindrical sealing body comprising an upper and a lower end surfaces, wherein an outer side and an inner side of at least one end surface of the sealing body are provided with an outer metal retaining ring and an inner metal retaining ring respectively, a fabric covering layer is disposed on the at least one end surface, and the outer and inner metal retaining rings are respectively pressed against an outer and inner edges of the fabric covering layer such that the fabric covering layer provides support for the outer and inner metal retaining rings. Through the outer and inner metal retaining rings, compression resistance of the slip sealing structure can be improved, and rubber extrusion at high temperatures and high pressures can be avoided; the fabric covering layer enhances performances of compression resistance and gas explosion resistance of the slip sealing structure.
