Using the national invention patent equipment, the proppant embedment experiment was carried out on the formation coal seam. The effects of proppant embedment on the conductivity of cracks under different proppant types, different proppant particle sizes, different sanding concentrations and different closing pressures were investigated. The experimental results show that with the increase of the closing pressure, the conductivity of quartz sand and ceramsite decreases rapidly; the conductivity of ceramsite is generally higher than that of quartz sand; the higher the concentration of sand, the proppant filling The stronger the layer’s compressive capacity and crushing resistance, the higher the fracture conductivity. XY ceramsite has the best conductivity.
