Manufacturing method and experimental method of physical model of fracture body oil reservoir

The invention discloses a manufacturing method and an experimental method of a physical model of a fracture body oil reservoir. The model is formed by taking transparent resin as a main material and cementing a plurality of layers from bottom to top. Cracks with different scales of 0.5mm, 1mm, 1.5mm, 2mm, 3mm and the like are reserved between the layers; the crack with the size of 3mm is used as a fracture layer in the middle and the cracks with other scales are distributed at the two sides of the fracture surface; the crack layers are communicated by a plurality of cracks with the width of 1mm; the inclined angles of the cracks of each layer are 9.46 degrees, 18.44 degrees, 26.56 degrees, 33.69 degrees and 39.81 degrees respectively from bottom to top; then the central position of the top end of the model is punched from top to bottom and the whole model is punched to be used as an oil well; a pipeline is inserted to be used as a sleeve and holes are punched at the crossed position of the pipeline and the fr
