| description | FIELD: oil industry. ^ SUBSTANCE: method for extraction of oil deposit by forcing a buffer of hydrocarbon solution into bed, containing surfactant, through force wells and extraction of oil through product wells, a buffer is forced into bed, containing non-ionized surfactant diproxamine-157 and additionally polyalkylbenzole resin at mass ratio 1:1-9 or non-ionized surfactant diproxamine-157 and additionally polyalkylbenzole resin and polyglykols with mass ratio 1:1-5.56:0.03-0.33 respectively with concentration of mixture of these components in hydrocarbon solution 0.1-5.0 percents of mass at amount 5-20% of porous volume, with following displacement of it along the bed by forcing agent. As forcing agent, water or agent buffer is used with movement ability picked for current bed conditions combined with water. In case of highly non-homogenous beds buffers of hydrocarbon solution and forcing agent are forced several times and alternately. ^ EFFECT: higher oil yield. ^ 3 cl, 7 tbl |
