摘要 |
FIELD: development of oil pools; applicable in development of carbonate formations of fractured-porous type. SUBSTANCE: method includes drilling of producing and injection wells; withdrawal of products through producing wells; water shutoff operations in producing wells by injection of grouting reagent of selective action with subsequent treatment of bottom hole zone with acid composition; portion injection of said grouting reagent with its forcing through definite distance. Bottom-hole zone is subjected to treatment with acid-oil mixture with rupture of formation blocks by system of fractures. Said acid-oil mixture is also used as displacing fluid.
