FIELD: mining.
SUBSTANCE: modified proppant contains the particle of proppant substrate, coated with a polymer hydrogel, wherein the mentioned particle contains a resin-coated proppant and the adhesion promoter, bonding them. The manufacturing method of the mentioned proppant includes the provision of the substrate particle and a composition, containing the coating precursor, application of this coating to the substrate particle and polymerization, forming the mentioned proppant. The composition for hydraulic fracturing contains the above mentioned proppant and oxidating or enzymatic breaker fluid. The invention is developed in the formula dependent claims.
EFFECT: stability of proppant increase in the hydraulic fracturing.
