The utility model relates to a multifunctional pore aquifer well washing device which comprises an air compressor, an oil-water separator, a first high-pressure air pipe, a second high-pressure air pipe, a slag discharge pipe, a conical filter head, an underwater pneumatic percussion drill, a water-slag separation box and a separation box return water pipe. The air compressor is connected with theoil-water separator, pollutants generated when the air compressor works can be effectively prevented from entering underground water along with compressed air, the slag discharging pipe entering a well is connected with the underwater pneumatic percussion drill in parallel, and the bottom end of the underwater pneumatic percussion drill is lower than the conical filtering head of the slag discharging pipe. The underwater pneumatic percussion drill is matched with the deslagging pipe to conduct deslagging on an underwater sandy gravel landfill well site, the well washing effect is greatly enhanced, and the device is s
