| titleOfInvention | Air blowing type foaming agent for removing hydrogen sulfide in foam isolation of oil extraction well head |
| abstract | The invention relates to the field of removing harmful gas in oil exploitation, and discloses an air blowing type foaming agent for removing hydrogen sulfide from an oil exploitation wellhead foam isolation, wherein the air blowing type foaming agent comprises the following components in parts by mass based on 100 parts by mass: (1) 2.0-4.0 parts of surfactant foaming agent; (2) 1.0-2.0 parts of a foam stabilizer; (3) 1.0-2.0 parts of tackifier; (4) 2.0-4.0 parts of reinforcing agent; (5) 3.0-6.0 parts of a chemical desulfurizer; (6) and the balance: deionized water. The invention has a wonderful idea across fields, creatively introduces the foam isolation fire extinguishing technology in the fire fighting field into the hydrogen sulfide removing technology of the well site in the oil exploitation field, fundamentally stops the leakage of hydrogen sulfide, and ensures that well site workers are prevented from being harmed; the consumption of desulfurizer at the oil extraction well mouth is greatly reduced; the problem of non-naphthalene well sealing caused by over standard of hydrogen sulfide is solved. |
