| titleOfInvention | Method for water drainage and gas production by adopting high-temperature-resistant high-salt foam drainage agent |
| abstract | The invention relates to a method for drainage and gas production by adopting a high-temperature-resistant high-salt foam drainage agent, which mainly solves the problem that the existing foam drainage 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 relates to a method for drainage and gas production by adopting a high-temperature-resistant high-salt foam drainage agent, which comprises the following steps: (1) mixing the foam drainage agent with water to obtain a foam drainage agent solution; (2) fully contacting a foam drainage agent solution or a mixed solution of the foam drainage agent solution and oil with gas to form a foam fluid, and displacing water or an oil-water mixture in the foam drainage agent solution; the foam water draining agent comprises the following components in parts by weight: the technical scheme of 1 part of polyamine surfactant and 0.01-100 parts of cosurfactant well solves the problem and can be used for drainage and gas production of acidic high-temperature high-salinity ultra-deep gas wells. |
