Beschreibung
Zusammenfassung:	FIELD: mining industry. ^ SUBSTANCE: composition includes polymeric microparticles capable of increasing in volume and possessing increased cross-linking property. Before increasing in volume, average diameter of particles is from about 0.05 to about 10 micron. Content of cross-linking agent is from 6,000 billion to 200,000 billion of unstable cross-linking agents and from 0 to 300 billion of stable cross-linking agents. Composition is used for changing permeability of underground layers and increasing velocity of mobilization and/or withdrawal of hydrocarbon fluids available in layers. ^ EFFECT: improved permeability of underground layers and increased velocity of mobilization or withdrawal of hydrocarbon fluids from underground layers. ^ 40 cl, 11 tbl, 14 ex
