The utility model relates to the technical field of oil field crude oil exploitation, in particular to an aerodynamic force jet negative pressure pump. The device comprises an outer pipe, the upper end of the outer pipe is connected with a gas injection system, the lower portion of an inner pipe is arranged in the outer pipe, the bottom end of the outer pipe and the inner pipe are sealed, the upper end of the inner pipe extends out of the outer pipe and is connected with a ground crude oil treatment system, the bottom end of the inner pipe is connected with a pump valve, and a nozzle is connected into the lower end of the inner pipe and comprises an outer body and a throat pipe body arranged in the outer body. And an oil inlet channel is arranged between the outer body and the throat pipe body. The pneumatic jet negative-pressure pump realizes pneumatic jet negative-pressure oil extraction, reduces density, is high in pressure and increases relative lifting capacity after crude oil and natural gas are mixed,
