FIELD: oil and gas production. ^ SUBSTANCE: spherical ceramic propping filler designed for oil or gas wells hydraulic fracturing is characterised with recesses on its surface. The procedure for forming recesses on surface of spherical ceramic propping filler consists in stages of drying, crumbling and granulation of raw stock with a successive stage of granulated material sintering. Also, the procedure does not include stages of calcination before the said stage of granulation. Here is also disclosed the procedure for oil or gas wells hydraulic fracturing where the above described propping filler is used as propping filler for hydraulic fracturing. The invention is developed in dependent points of formula. ^ EFFECT: raised efficiency of extraction of oil or gas from wells. ^ 13 cl, 4 tbl, 7 dwg |
