Test allocation device for layered injection well and installation method for same

The invention discloses a test allocation system for a layered injection well and an installation method for the same. The device and the method belong to the field of layered water injection in the petroleum industry. The method comprises the steps that a hydraulic lifting device is installed at a well mouth; a cable is laid, and one end of the cable passes through a top anti-spray sealing device and is then connected to a test allocation instrument; the hydraulic lifting device inclines an anti-spray tube, and the test allocation instrument with the cable is put into the anti-spray tube; the top anti-spray sealing device is installed on one end of the anti-spray tube; the hydraulic lifting device makes the anti-spray tube vertical and fixes the anti-spray tube at the well mouth of the layered injection well; and the test allocation instrument is put down, and the test allocation instrument is butt-jointed with a packer in a bridge-type eccentric water distributor.
