FIELD: oil production. SUBSTANCE: method for developing oil deposit with flooded prostrate includes pumping gel-generating material and water in the flooded stratum through pressure well and extraction of liquid through production well. Gel-generating material is held for 24 hours. Water pumping in is carried out prior to decreasing flammability of produced liquid in nearest production wells. Then pressure wells are stopped and started periodically. The following composition is used as gel-generating one: 50 70 kg of nepheline per 1 m3 of 10 solution of hydrochloric acid. EFFECT: effective method for developing oil deposit.
