This invention relates to the technical field of uranium-containing fluids, and more particularly to a device and method for simulating the transport of uranium-containing fluids under oxygen-deficient conditions. The reaction mechanism includes a U-shaped glass tube placed vertically, with an outlet on the top right and an inlet on the bottom left of the tube, and a rubber stopper at the top opening. A supply mechanism includes a helium cylinder located on the left side of the U-shaped glass tube, with a pressure-reducing valve installed at its outlet. The outlet of the pressure-reducing valve is connected to a filling gun, the other end of which can be quickly connected to the inlet. By laying sandstone strata inside the U-shaped glass tube and using a helium oxygen-removal method to create an oxygen-deficient atmosphere, the transport scenario of uranium-containing fluids under real geological conditions can be highly replicated. Combined with a thermal insulation jacket and temperature controller for precise temperature control, the experimental results are closer to natural geological processes, providing reliable data support for the study of uranium transport mechanisms.
