FIELD: geotechnological mining operation methods, particularly for oil extraction from unstable and semiconsolidated reservoirs.
SUBSTANCE: composition comprises binding agent, additive, structure-forming agent and water. Binding agent is polyurethane hydrophilic pre-polymer, structure-forming agent is sodium chloride free from hydration water, additive is sand. All above components are taken in the following amounts (% by weight): polyurethane hydrophilic pre-polymer - 7-15, sodium chloride - 18-48, sand - 24-55, water - remainder.
EFFECT: increased oil recovery from reservoir, provision of necessary filter permeability and strength parameters, provision of filter hydrophilic behavior.
