FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil-field equipment intended for storage and dosed supply of working agents to hydrocarbon-containing productive strata of hard-to-recover hydrocarbon reserves. Plant includes modules for storage and supply of working agents, each of which contains container for working agent, output of which is connected to input of pump unit, connected by outlet pipeline to supply pipeline, connected to input of high-pressure pump, which output by means of the pressure pipeline is able to connect to the tubing string located in the well and in the productive formation zone. Plant is equipped with a module for storage and metered water supply, containing a water tank, the output of which is connected to the inlet of the pump unit, connected by the outlet pipeline to the supply pipeline, in output pipeline of each module and in delivery pipeline there is a controlled check valve, outlet pipelines of modules are connected to supply pipeline in parallel, wherein output pipelines of modules for storage and dispensing of working agents are connected to supply pipeline between outlet pipeline of module for storage and metered supply of water and high-pressure pump.
EFFECT: higher safety of plant operation.
