FIELD: oil and gas production.
SUBSTANCE: invention deals with development of foamed cryogel materials, which can be used in construction and arrangement of oil and gas wells in north regions, during restoration of land in cryolite zone regions, and in oil production and oil transportation processes. Composition contains polyvinyl alcohol, water as solvent, and additionally sodium chloride, carbon black, and glycerol. Foamed cryogel is formed via air-assisted foaming of proposed composition followed by freezing-thawing cycle.
EFFECT: enabled preparation of foamed cryogel having thermal and mechanical properties suitable for heat insulation of producing wells and for prevention of paraffin deposit accumulation therein.
