METHOD FOR INTENSIFYING INFLOW OF HYDROCARBONS TO WELL Russian patent published in 1999 - IPC

FIELD: oil and gas production industry. SUBSTANCE: method relates to well-type development of oil and gas deposits and can be used for increasing output capacity of producing wells. According to method, determined are geological, physical and chemical properties of productive bed rock and bed fluids. Lowered into well is string of pump-compressor pipes, and successively injected into well-adjoining part of bed are selected portions of chemical reagents. Prior to treatment of well-adjoining part of bed and after delivery of each chemical reagent, gas is injected into well-adjoining part of bed so as to create higher pressure zone which is supersaturated with gas. Pressure in this zone exceeds value of bed pressure. After maintaining well for period of current reactions of chemical agents with rock of productive bed and bed fluids, bottom-hole zone of bed is cleared from reaction products by putting well in operation. EFFECT: higher efficiency. 1 dwg
