METHOD OF SIMULTANEOUSLY-SEPARATE DOWNLOADING OF THE WORKING AGENT, INSTALLATION AND REGULATORY DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC E21B43/14 E21B43/12 

FIELD: machine building.

SUBSTANCE: invention relates to maintaining reservoir pressure in multilayer fields and can be used with simultaneous-separate injection (SSI) of a working agent. When carrying out the first tripping operation (TO), a tubing string is used to lower pressure test valve, lower packer, disconnector and hydraulic valve, during the second tripping the tubing string is used to lower the measuring transducer, regulating device, upper packer, safety node, cable made single-core or stranded, which is connected to measuring transducer using the first branch, and to the lower and upper electric valves of regulating device using the second branch. Control station has intelligent unit, assembly equipped with safety unit located above the upper packer, regulating device that is concentric in tubing above the lower packer above the upper layer, transmitter located under regulating device and equipped with external pressure sensor and internal flow, pressure and temperature sensors, disconnector is located above the lower packer.

EFFECT: increase in effectiveness of simultaneous-separate injection of the working agent.
