The invention discloses an oil-gas well perforator ground target shooting test device, and belongs to the field of oil-gas well perforating simulation testing. The oil-gas perforator ground target shooting test device comprises a concrete target, a test sleeve, a pressure maintaining tube, a piston, a shear pin and a protective steel plate. According to the invention, a high temperature and high pressure liquid is pumped into a test sleeve through a pressure testing pump so as to simulate an underground high temperature and high pressure environment, the pressure maintaining tube is internally provided with the piston, the shear pin penetrates through the pressure maintaining tube along the radial direction of the pressure maintaining tube and is inserted into the piston, the pressure in the pressure maintaining tube is released by using the shear pin, and the pressure release delays relative to secondary energy release of a perforator in time, so that the test sleeve is enabled to still maintain the simulate
