Hard tank waterflooding apparatus for column-type platform straightening process

The utility model relates to a hard tank waterflooding apparatus for column-type platform straightening process. The characteristic of the apparatus is that the apparatus comprises three waterflooding tanks disposed at the bottom of the hard tank, and each of the waterflooding tank is provided with a water injection pump, a waterflooding pipe outside the tank, a waterflooding port, a waterflooding pipe inside the tank, an air outlet of the hard tank and an air outlet of the waterflooding tank. The water injection pump is disposed outside the hard tank, with a water inlet sopped in water and a water outlet connected with one end of the waterflooding pipe outside the tank. The waterflooding pipe outside the tank is also disposed outside the hard tank, and both ends of the waterflooding pipe outside the tank respectively connect with the water outlet of the water injection pump and the waterflooding port. The waterflooding port is disposed at the top of the hard tank, and both ends of the waterflooding port respectively connect with the waterflooding pipe outside the tank and the waterflooding pipe inside the tank. The waterflooding pipe inside the tank is disposed in the hard tank, and both ends of waterflooding pipe inside the tank respectively connect with the waterflooding port and the waterflooding tank at the bottom of the hard tank. The air outlets of the hard tank are disposed at the top of the hard tank above the waterflooding tank. The air outlets of the waterflooding tanks are on the tank wall, close to the top of the waterflooding tanks when the column-type platform is in horizontal state. The hard tank waterflooding apparatus can be widely applied in the process of column-type platform straightening.
