Abstract: The present disclosure discloses an experimental apparatus and method for simulating transport of a sand-carrying fluid in a fracturing fracture. The apparatus may include a spiral proppant transport device, a stirred tank, a screw pump, a liquid transport pump, a pressure gauge, a proppant transport and distribution system, a cyclone desander, a waste liquid recycle container, a proppant recycle container, and a fracturing fluid tank. The spiral proppant transport device may be communicated with the stirred tank. The waste liquid recycle container and the fracturing fluid tank may be communicated with the stirred tank via the liquid transport pump. A bottom end of the stirred tank may be communicated with the proppant transport and distribution system through the screw pump. It is possible to simulate the sand-carrying fluid paved under a closure pressure by setting a computer to precisely control a transparent cuboid fracture member including hydraulic tanks.
