Abstract (English):
Researches of process of replacement of model oil by viscosity 38 mPas∙s in the range of pressure to 14 MPas on isotherms 313 and 333 To on uniform layer by permeability 0,038 мкм 2 are conducted. Are revealed optimum the volume of forcing of СО 2 on an isotherm 333 K and the optimum pressure of forcing for obtaining the maximum oil recovery on an isotherm 313 K. Formation of the steady water oil emulsions resulting downloading in layer of water and decrease in their contents in volume of forced-out liquid with temperature increase of forcing of water is revealed.
