Summary:FIELD: oil production industry. SUBSTANCE: compound can be used for increasing oil recovery from bed by drowning due to selective clogging of highly permeable interlayers by microbic biomass. These interlayers are washed with water. Application of compound ensures involvement into operation of poorly involved oil saturated interlayers and zones of bed at late highly drowned stages of developing oil deposits. Compound for displacing oil from bed includes following components, mas.%: dry active silt from biological purification facilities of cellulose-paper production enterprises, 0.5-15.0; steam-treated sulfite liquor, 5.0-11.0; additionally trixane, 0.05-0.2; water, the balance. Application of aforesaid compound results in increasing activity of biochemical processes in displacement of oil together with dissolving effect brought to bear on asphaltic-resin components. Also foaming is prevented in preparation of working solution for injection into bed. EFFECT: higher efficiency. 2 tbl
