COMBINED METHOD OF EQUALIZING OF OIL DISPLACEMENT FRONT

摘要

FIELD: oil-producing industry; particularly, methods of development of oil fields. SUBSTANCE: method includes injection of water and high-viscosity agent into formation with subsequent explosion or formation of hydraulic fracturing of such a power that formed fracturing zone equals radius of penetration of high- viscosity agent in the most low-permeable interlayer or close in permeability but considerably differing from highly permeable interlayers. EFFECT: higher oil recovery from nonuniform permeable formation. 1 dwg
