FIELD: oil and gas industry.
SUBSTANCE: method of oil extraction from solid source rocks includes: grinding of said rocks with production of particles with size 5 mm maximum, densimetric separation of said particles, including: particles mixing with water and deflocculant with creation of the first mixture solid substance-liquid, its division with creation of supernatant enriched with oil, and oil depleted precipitated residues, extraction of the supernatant, its mixing with at least one organic solvent with boiling point 160°C maximum at 5-40°C and atmosphere pressure 0.1MPa (1 atm) with creation of the second mixture solid substance-liquid, its division with creation of liquid phase containing said oil and said organic solvent, and solid phase containing residues of said rocks, said solvent extraction from said liquid phase.
EFFECT: increased extraction efficiency.
