The invention discloses a fine gas flow testing tubular column capable of injecting gas layer by layer. Comprising a cable connector arranged at the upper end of the tubular column; the electric telescopic supporting arm is arranged at the middle upper part of the tubular column; the gas inlet is formed in the middle of the tubular column in the radial direction; the venturi tube is arranged in the tubular column and is positioned below the gas inlet; the gas outlet is formed in the tubular column in the radial direction and located below the Venturi tube; the upper compression sealing ring is arranged at the lower part of the Venturi tube; the lower compression sealing ring is arranged below the gas outlet; and the compression driving mechanism is arranged below the lower compression sealing ring. The device has the beneficial effects that sealing of a gas channel in the Venturi tube is achieved through the upper compression sealing ring and the lower compression sealing ring, and therefore flow collection a
