OIL DEPOSIT DEVELOPMENT METHOD Russian patent published in 2013 - IPC E21B43/20 

FIELD: oil and gas industry.

SUBSTANCE: in the course of deposit development there performed is the pumping of working medium into injection accepting wells by cross-well pumping of produced water from well-donor and extraction of product from production wells. There analysed are the development conditions and possibility of simultaneous stopping of one or several accepting wells and/or changing of working medium pumping modes into accepting wells depending upon development requirements. Electric centrifugal pump in well-donor is replaced by pump of larger capacity with frequency-regulated drive considering the provision of working medium supply without breaking out into accepting wells in normal mode as well as in varying mode at stopping of one or several accepting wells and/or changing of working medium pumping modes into accepting wells depending upon development requirements. Electric current frequency for feeding newly installed pump is reduced and increased depending upon the varying mode.

EFFECT: increase of stability of injection wells operation and possibility to control their work depending upon development conditions.
