FIELD: oil, gas and coke-chemical industry.
SUBSTANCE: invention relates to the oil industry and is intended to activate the development of residual recoverable oil reserves from deposits. Method involves pumping of displacement fluid — formation water through injection wells and oil extraction to the surface through production wells. When implementing the method, a production well with high water cut of more than 90% and an injection well hydrodynamically connected to a production well with injectivity of 250–300 m3/day are determined. Bottom-hole pressure is increased in production well by 10–15% at liquid production at the same level, and volume of pumped liquid to injection well is increased by 40–60%.
EFFECT: increased efficiency of oil deposit development and increased oil recovery of the formation.
