FIELD: chemistry.
SUBSTANCE: microemulsion for oil extraction contains the following in wt %: polyethylene polyamine with molecular mass of 144 and content of tertiary amino groups of 6.6 wt % 3.41-9.00, oleinic acid 7.84-20.91, isopropyl alcohol 3.75-10, kerosene 15-40, water - the rest. The ratio oleinic acid : polyethylene polyamine with molecular mass of 144 and content of tertiary amino groups of 6.6 wt % equals 1.6:3.0 wt, the ratio isopropyl alcohol : polyethylene polyamine with molecular mass of 144 and content of tertiary amino groups of 6.6 wt % equals 0.6:1.1 wt.
EFFECT: reduced viscosity of microemulsions and increase of their permeability in rocks of oil formations.
