The application discloses a plunger for carrying liquid foaming agent in water drainage gas production, which comprises a plunger outer cavity and a plunger shaft block; a lower cavity is left between the plunger outer cavity and the plunger shaft block, the lower cavity is filled with a foaming agent, and a liquid discharge one-way valve for outputting from inside to outside is arranged on the outer side wall of the lower cavity; the plunger shaft block is internally provided with a cavity, a mass ball and a limiter are arranged above the cavity, the mass ball is used for penetrating the limiter under the action of inertia and moving towards the lower part of the cavity; a spring buffer is arranged below the cavity, the lower end of the spring buffer extends out of the lower end of the plunger shaft block from the cavity, and the mass ball is used for driving the spring buffer to extend towards the inside of the lower cavity. By adopting the scheme, the plunger is used as a carrier of foam falling when the plunger falls, the falling distance of the foam is prolonged, and the foaming effect is improved; when the plunger goes up, the foaming agent carried by the plunger generates a large amount of low-density water-containing foam under the agitation of gas-liquid two-phase flow, and the blowout time is sufficiently prolonged.
