The invention discloses a gas well foam scrubbing agent and a preparation method and application thereof, and belongs to the technical field of gas well chemical agents. The gas well foam scrubbing agent provided by the invention comprises alkyl acyl propyl trimethyl ammonium chloride, an amino acid surfactant, a betaine surfactant, high alcohol, amino acid sodium and solvent water, and the viscoelasticity of a foam liquid film and the stability of foam can be remarkably enhanced by compounding the components; on one hand, the high liquid-carrying capacity can be kept under the conditions of high temperature, high salinity and high condensate oil, and the water-draining and gas-producing device is suitable for water-draining and gas-producing of a deep-mining natural gas well; and on the other hand, the gas well foam scrubbing agent contains easily available raw materials, is easy to prepare, does not need a complex organic synthesis and/or purification process, has good degradation performance ...
