| titleOfInvention | High-temperature-resistant high-salt foam drainage agent, and preparation method and application thereof |
| abstract | The invention relates to a high-temperature-resistant high-salt foam water discharging agent, a preparation method and application thereof, and mainly solves the problem that the existing foam water discharging agent contains H 2 S、CO 2 The high-temperature and high-salt resistance in an acidic environment is poor, and the problem of production reduction and even blowout stop caused by liquid loading of a high-temperature and high-salt ultra-deep gas well cannot be solved. The invention comprises the following components in parts by mass: 1 part of polyamine surfactant and 0.01-100 parts of cosurfactant; wherein the polyamine surfactant has a general molecular formula shown in formula (1): the cosurfactant has the technical scheme that at least one of the zwitter-ion or cationic surfactant with the molecular general formula shown in the formula (2) or the anionic surfactant with the molecular general formula shown in the formula (3) better solves the problem and can be used for drainage and gas production of acidic high-temperature high-salt ultra-deep gas wells. |
