METHOD OF INCREASING OIL RECOVERY FROM BEDS

FIELD: oil production industry. SUBSTANCE: according to method, down-hole zones of injection and producing wells are subjected to treatment by suspension of highly dispersing hydrophobic silicone dioxide in organic solvent. Then water is injected into injection well. Oil is displaced from reservoir...

Beschreibung
Zusammenfassung:	FIELD: oil production industry. SUBSTANCE: according to method, down-hole zones of injection and producing wells are subjected to treatment by suspension of highly dispersing hydrophobic silicone dioxide in organic solvent. Then water is injected into injection well. Oil is displaced from reservoir by hydrodynamic pressure of water from down-hole zone of producing well. EFFECT: higher efficiency. 4 cl, 1 tbli
