Integrated proppant flat plate conveying experimental device and preparation method thereof

The invention discloses an integrated proppant flat plate conveying experimental device and a preparation method thereof. The experimental device comprises a main artificial fracture unit, a plurality of secondary artificial fracture units and a fracture filtration unit. The artificial crack unit is composed of an organic glass flat plate which is of an integrated structure, the surface of the organic glass flat plate is uneven, and the organic glass flat plate is in a continuous, integral and multi-branch spatial form. According to the device, factors such as the number and angle of the secondary artificial fractures, the roughness of the wall surfaces of the fractures, the change of the width of the fractures and the filtration loss of fracturing fluid are fully considered, and the form of the underground complex fractures is simulated more truly. The invention further discloses a preparation method of the integrated proppant flat plate conveying experimental device, the method is simple in processing proce
