The utility model relates to a screen pipe water control valve, its characterized in that: at the bottom of valve gap, valve and the kickboard, the valve gap with can dismantle the connection at the bottom of the valve, it is sealed to connect the back, valve gap upper portion is formed with the fluid entry, there is the fluid issuing bottom at the bottom of the valve, there is the cavity at the middle part at the bottom of the valve, the cavity with the fluid entry the fluid issuing intercommunication, the kickboard hold in in the cavity, just the kickboard freedom. The utility model provides an aperture of water control valve free kickboard in through the change control valve of the different fluid viscosities of the device of flowing through to realizing that the profit that viscosity is different carries out automatic differentiation, making in -place oil's inflow -rate of water turbine big, the inflow -rate of water turbine of formation water is little, reaches the purpose of steady oil accuse water. But the wide application is in the horizontal well.
