FIELD: mining.
SUBSTANCE: method consists in injecting into nearest to well borehole part mixture containing hydrocarbon liquid mixed with crude oil in ratio from about 0.5 to 2% of wt, ethoxylated alcohol from 0.2 to 2% wt at least one alkyl polyglycoside from about 1.5 to 4% wt, alcohol with linear alkyl at amount sufficient to fill part of formation of nearest to well borehole to radial distance outward from well borehole from 15.2 to about 91.4 cm; in maintaining this mixture in nearest to well borehole part for from about 8 to about 96 hours and removal of mixture from nearest to well borehole part. Also disclosed are compounds for removal of liquid from a reservoir and a composition for their preparation.
EFFECT: upgraded efficiency of removal of bound water from nearest to well borehole part.
