FIELD: oil and gas industry.SUBSTANCE: method for making a polymer-coated proppant involves coating the granules with a polymer of phenol formaldehyde resin with hexamethylenetetramine and liquid epoxy resin with a hardener; coating the granules is preceded by preparing a solution of phenol formaldehyde resin with hexamethylenetetramine, which is mixed with liquid epoxy resin with the hardener in ratio, wt %: liquid epoxy resin with the hardener 20-80 and the solution of phenol formaldehyde resin with hexamethylenetetramine 20-80 with the solvent content in the solution of phenol formaldehyde resin makes 5-90%. The invention is developed in the secondary claims.EFFECT: forming the integrated frame of a proppant pack.3 cl, 5 ex, 2 tbl |
