Graded water pumping device for pumping test

The invention discloses a graded water pumping device for a pumping test, and relates to the technical field of drilling exploration. The graded water pumping device for the pumping test comprises a plurality of water pumping units. Each water pumping unit comprises water pumping containers and water pumps, wherein the water pumps are connected to the corresponding water pumping containers, the multiple water pumping containers are sequentially connected and used for stretching into a to-be-explored drill hole and being distributed in the to-be-explored drill hole layer by layer, the water pumps are used for pumping water in the corresponding water pumping containers and conveying the water to the water pumping container of the water pumping unit above the water pumping unit in order to lift the water to the earth surface layer by layer, and the water pumping time and the pump output can be read in real time through a sensor in order to conveniently calculate a stratum permeability coefficient.
