Blowing type foaming agent for removing hydrogen sulfide by foam isolation at oil production wellhead

The invention relates to the field of harmful gas removal in oil exploitation, and discloses a blowing type foaming agent for removing hydrogen sulfide by foam isolation at an oil production wellhead.The blowing type foaming agent comprises the following components including, by mass (based on the total mass of 100 parts), 2.0-4.0 parts of a surfactant foaming agent, 1.0-2.0 parts of a foam stabilizer, 1.0-2.0 parts of a tackifier, 2.0-4.0 parts of a reinforcing agent, 3.0-6.0 parts of a chemical desulfurizing agent and the balance of deionized water. According to the blowing type foaming agent, a foam isolation fire extinguishing technology in the field of fire protection is creatively introduced into a well site hydrogen sulfide removal process technology in the field of oil exploitation, so that the leakage of the hydrogen sulfide is fundamentally avoided, and well site workers are prevented from being harmed; the consumption of an oil extraction wellhead desulfurizing agent is greatly reduced; and the pro
