MAGNETIC PROCESSING SYSTEM FOR OIL PRODUCTION Russian patent published in 2022 - IPC E21B37/00 

FIELD: oil industry.

SUBSTANCE: invention relates to the oil industry and is intended for magnetic processing during oil production. The system includes a producing well, an injection well, interconnected by a block for the collection and preparation of commercial oil and a working agent, in which magnetic processing devices (MPD) are installed in the processing equipment along the flow of oil and the working agent. The producing well consists of an operational column in which, sequentially along the course of the movement of the oil flow, a resonant wave complex with the first MPD, a submersible electric motor, a second MPD in the form of a magnetic activator and combined with the input module of an electric centrifugal pump connected through a tubing string are located with a wellhead valve, which is connected by a pipeline to a block for collecting and preparing commercial oil and a working agent containing a sequentially connected automated group measuring unit, the third and fourth MPD, demulsifier, separator-water eliminator connected to the oil reservoir, as well as through the fifth MPD to the waste water reservoir, which is connected to the modular injection pumping station, the sixth MPD, water distribution unit and filter connected by the pipeline to the wellhead fittings of the injection well, including the production column, in which the tubing string with a packer and are sequentially located along the course movements of the working agent. The seventh MPD is connected to the tubing string with a chain of permanent magnets located in the lower part of the base of the tubing string with the possibility of transferring the working agent through the oil reservoir to the producing well.

EFFECT: corrosion activity, deposition of salts and asphalt-resin paraffins on the processing equipment of injection and production wells, in the bottom-hole zone and oil reservoir are reduced.
