METHOD FOR ENERGY-CYCLIC TREATMENT OF WELL IN BED OF NONUNIFORM PERMEABILITY Russian patent published in 1999 - IPC

Abstract RU 2134776 C1

FIELD: oil production industry. SUBSTANCE: according to method, oil bed is opened and subjected to hydraulic fracturing, energy carrier is injected into well in cyclic manner, and well is stopped for reaction with subsequent recovery of oil. In first cycle, energy carrier is injected at minimal pressure of hydraulic fracturing of bed. In subsequent cycles, injection pressure is successively increased to maximal value of hydraulic fracturing of bed. Application of aforesaid method increases embracing of oil bed by effect produced by energy carrier. EFFECT: higher efficiency. 1 cl, 5 dwg
