The disclosure relates to a hard-sealing soluble bridge plug, comprising a body made of soluble metal. The body comprises a wedge, a slip and a guide shoe which are connected from top to bottom in turn; at least one metal sealing ring is sleeved at the junction of the outer circumference of the wedge and the slip, and the metal sealing ring is made of soluble metal. The hard-sealing soluble bridge plug provided by the disclosure is applied to the field of fracturing and stimulation operation of an oil and gas well so that the hard-sealing soluble bridge plug is more convenient to store, more stable to seal and more firm to anchor, the setting success rate of the hard-sealing soluble bridge plug is effectively improved to better adapt to down hole environments. Furthermore, due to simple and compact structure, the hard-sealing soluble bridge plug is easy to machine and manufacture, and is effectively reduced in the cost of the soluble bridge plug.
