METHOD FOR DEVELOPMENT OF OIL POOL

摘要

FIELD: oil-and-gas industry, particularly, methods for development of oil objects. SUBSTANCE: method consists in that injected precipitating system penetrates far enough from injection well and sufficiently plugs the channels of abnormally low filtering resistance with simultaneous increase of treated area. This makes it possible to considerably enhance the sweep efficiency by flooding and oil recovery as compared with the known method of formation stimulation. Selectivity of wells by repair-isolation work and work involved in intensification of oil recovery from producing wells allows additional oil recovery from formation and intensification of the process of development of oil objects. EFFECT: increased oil recovery and energetics of operation of oil formation.
