METHOD OF OIL POOLS DEVELOPMENT IN CARBONATE RESERVOIRS Russian patent published in 2000 - IPC

Abstract RU 2147678 C1

FIELD: oil-producing industry, particularly, methods of development of oil pools; applicable in raising the efficiency of oil reserve recovery. SUBSTANCE: method consists in drilling of pools by system of vertical and horizontal wells with formation of accumulating covers by jets of mineral acid solution at velocity of solution flow at least 50 m/s. In this case, added to solution of mineral acid may be 0.01-1.0 wt.% of dispersion phase. Final coefficient of oil recovery increases by 8-13%. EFFECT: higher efficiency of oil reserve recovery. 2 cl, 2 tbl, 2 ex
