The invention is directed to enhancement of the effectiveness of the proppan t as a result of increasing its strength, providing high permeability of the layer of proppant in the well. This result is achieved in that in the method of producing proppant from glass spheres, comprising preparing a melt of oxides, with forming spheres and cooling them, additiona l retention of the prepared spheres is carried out at 870-1100.degree.C for 8-25 minutes to the formation of a glass crystalline structure. Wherein it is possible that the glass crystalline structure contains at least 40% crystalline phase, preparation of the melt is carried out by feeding gla ss powder in a gas stream, said cooling and retention are carried out in one thermal device, th e method itself is carried out in a rotary furnace.
