METHOD OF DEVELOPING OIL DEPOSITS Russian patent published in 2018 - IPC E21B43/20 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas production industry, in particular, to methods for enhancing oil recovery. Method of developing oil deposit involves selection of oil through producing wells and injection of working agent through injection wells in cyclic mode with injection by fixed cycle of injection and idle by day. Initially, average daily volume of water pumped into reservoir is determined for stationary water flooding. Then, water is pumped into injection wells with pressure of 10–15 % less than fracture pressure and in volume three times larger than certain average daily volume of water. Download is made during day in combination with three days of downtime. At the time of injection in production wells that are hydrodynamically associated with injection wells used, production is reduced by 70 % or more, until plant completely stops.

EFFECT: claimed invention makes it possible to increase oil production and prevent premature watering of produced products.
