The utility model relates to a testing device for downhole layered water injection, which comprises a display instrument, a casing pipe, a plurality of oil pipes and a packer. The utility model is characterized in that a fishing head, a converter, and a injection allocation core which are connected via threads are arranged inside the oil pipe; a connecting joint and a water distributor working barrel of a connecting pipe which are connected via threads are arranged between the oil pipes, and are positioned downwards to the water injection layer; the converter is arranged on the bottom of the well; injected water from the oil pipes passes the converter and the injection allocation core, and flows to the strata for downhole layered collection and measurement, then the display instrument on the ground is used to read the data collected by the converter; after the testing, the injection allocation core and the converter are plunged into the well again for successive water injection. The utility model has the advantages that as the automatic control measurement of the daily water injection amount and the total water injection amount of the layered water injection well is realized, manpower is saved, efficiency and quality of the water injection is improved, and a new approach is created for the testing of the water injection well of the oilfield.
