The invention discloses a blockage removal method and a blockage removal device for a microwave hydrate for a gas well. The deicing technology adopted by the conventional natural gas wells and carbon dioxide gas wells is that: 1, a well mouth or a gas pipeline is heated by adopting a water jacket furnace; 2, methanol and other inhibitors are added into the gas wells; 3, the carbon dioxide gas is heated by means of terrestrial heat of the stratum; and 4, an oil pipe gas recovery mode is changed into a sleeve gas recovery mode. The deicing technology has the disadvantages of severe environmental contamination, complex technology, high labor intensity and strict technical requirement. The blockage removal method is that: a high-frequency microwave power source is adopted and is guided into a well tube through a wave head pipeline, and a waveguide channel is formed by the well wall tube; and microwave electromagnetic waves are transmitted to a hydrate freezing blockage point in an enclosing way, so that the freezing blockage point is irradiated by the high-frequency electromagnetic waves, gets energy, raises the temperature and is dissolved. Therefore, the freezing blockage problem of the hydrate is solved. The blockage removal method is used for unfreezing the gas wells.
