The utility model relates to a steam negative pressure pump, comprising an inner working barrel and an outer working barrel. The inner working barrel and the outer barrel are both hollow tubes, which are respectively provided with joints at the upper end. A spout is inward sleeved in the upper contact of the inner working barrel. An energy converter is inward sleeved in the inner working barrel under the nozzle of the spout. The lower part of the inner working barrel is provided with an oil outlet hole. A circular space is formed by the nozzle of the spout and the inner working barrel, and the walls of the inner working barrel and the outer working barrel correspondingly to the circuit space are provided with pore canals which can be inserted into oil inlet pipes. The lower end of the outer working barrel is sealed by a filament plug. When processing the viscous oil exploitation, the high pressure steam is injected from the spout of the steam negative pressure pump and jetted out at a very high speed from the nozzle of the spout. In this way, a definite negative pressure is formed in the circular space formed by the nozzle of the spout and the inner working barrel. The viscous oil in the oil layer is sucked into the energy converter through the oil inlet pipe of the oil inlet pore canal to do the energy converting and make the velocity energy converted into the pressure energy, in this way, the viscous oil is raise to the ground by pressing into the circular space of the inner working barrel and the outer working barrel through the oil outlet hole.
