摘要: The invention discloses a swirl flow-in controller. controller mainly comprises two components including swirling fluid (1) and valve cover (2). is provided with tangential inflow passage (111), (121) chamber (10). characteristic that since different fluids are in viscosity, the energy consumption of fluidsin utilized, flow restriction on specific achieved. has advantages problem water breakthrough non-homogeneousoil reservoirs too early solved, can effectively lower speed side water, bottom injection water-free oil recovery period prolonged;at same time, effects stabilizing reducing achieved for wells breakthrough.
