FIELD: oil and gas industry.
SUBSTANCE: invention relates to the field of stimulation of oil production using mixable solvent displacing oil from the formation. Essence of inventions: system for oil production from subsurface formation includes the following: the source of mixable solvent containing carbon bisulphide; a device intended for production of emulsion containing the above mixable solvent; a device intended for emulsion storage with capacity of at least 5000 gal of emulsion; the first row of wells distributed above the formation; the second row of wells distributed above the formation; a device for emulsion breaking connected to the device for emulsion storage and the first row of wells; at that the first row of wells includes a device for pumping of the mixable solvent to the formation while the second row of wells includes a device for oil extraction from the formation.
EFFECT: improving efficiency and reliability of oil displacement system.
