Abstract
The invention relates to a high-performance composite foam scrubbing agent for a gas well and a preparation method thereof. The invention discloses a high-performance composite foam scrubbing agent for a gas well. The high-performance composite foam scrubbing agent comprises a composite foaming agent and a foam stabilizer, the composite foaming agent is a composite zwitterionic surfactant, an anionic surfactant and a nonionic surfactant; the foam stabilizer is hydrophilic nano silicon dioxide. According to the high-performance composite foam scrubbing agent for the gas well and the preparation method of the high-performance composite foam scrubbing agent, the foam scrubbing agent which is excellent in foaming performance and liquid carrying rate and suitable for the actual production environment is obtained through joint compounding of hydrophilic nano-silica and foaming agents of various surfactants.
