METHOD OF FORMATION TREATMENT Russian patent published in 2002 - IPC

FIELD: oil producing industry; applicable in restoration of permeability of bottom-hole zone of oil-gas bearing formation under conditions of clogging accumulation. SUBSTANCE: essence of the invention consists in location in well of insulated charges of aluminum-containing hydroreacting composition including at least aluminum activated, at least with gallium. Reaction is conducted at linear weight of hydroreacting composition of 0.25-2.9 kg/t. Said composition is brought into contact with well fluid. Reaction is conducted so that pressure and temperature in well do not exceed level at which damage to well may occur. Pressure and temperature within interval of producing formation are maintained at the level ensuring restoration of permeability of bottom-hole zone. EFFECT: ensured restoration of bottom-hole zone permeability under various geological conditions due to using of hydroreacting compositions with high energy characteristics and more efficient use of liberating energy. 14 cl, 5 dwg, 7 tbl
