APPARATUS FOR DOSED SUPPLY OF CORROSION INHIBITOR SOLUTION TO PROCESS PIPELINES OF GAS CONDENSATE WELLS Russian patent published in 2020 - IPC E21B37/06 F17D3/12 

FIELD: pumps; chemistry.

SUBSTANCE: invention relates to installations for dosed supply of chemical reagents into process pipelines of wells. Plant includes corrosion inhibitor solution supply container, outlet pipeline of which is equipped with centrifugal electric pump and regulator of total consumption of corrosion inhibitor, consisting of solution bypass line into supply tank, equipped with shutoff-control valve with electromechanical drive, and liquid flow rate meter installed on outlet pipeline. Output pipeline is connected to distributing cluster header, each of branches of which represents a cluster pipeline with installed on it cluster flow regulator of corrosion inhibitor solution, consisting of liquid flow counter and shutoff-control valve with electromechanical drive. Outlet of each of cluster pipelines is connected to distribution well reservoir, each of the branches of which is a downhole pipeline with a corrosion inhibitor solution consisting of a liquid flow rate meter and a shutoff-control valve with an electromechanical drive installed on it. Output of each downhole pipeline, equipped with check valve, is connected to process pipeline of well, and regulators by means of local automatic control systems are connected to automated process control system.

EFFECT: higher manufacturability of plant, higher accuracy of regulating consumption of inhibitor.
