FIELD: oil and gas industry. ^ SUBSTANCE: method includes feeding solution into face area of oil-gas bed with following energy treatment of bed and solution, fed into face zone of bed. Bed and face zone are magnetized by feeding solution thereto, containing suspended hard magnetic particles with size within range from 80 to 250 mcm. These produce permanent magnetic field with induction from 0.2 to 12.5 Tesla. Feeding of ferromagnetic solution is possible, for example, based on polyethylenesiloxane liquid or on synthetic hydrocarbon oil of olefin polymer C5-C20. then magnetized oil-gas containing bed is excited as well as its face zone by affecting their magnetic field with source of permanent magnetic field with induction 0.5-22.5 Tesla and its periodical upward-downward movements along bed for distance, selected from relation 0.43:4.12 from thickness of bed. Periodicity of movement of magnetic source movement is 2-6 times per minute in even or nonevent time intervals, or continuously. As permanent magnetic field source, cylindrical compound permanent magnet is used, made in form of set of interconnected ring-shaped permanent magnets with radial magnetization. Ring-shaped permanent magnets with radial magnetization pole on their outer cylindrical surface are alternated in compound permanent magnet with ring-shaped permanent magnets with radial magnetization pole on their outer cylindrical surface. Magnetic treatment of bed during movement of compound permanent magnet is performed alternately, first, by magnetization pole of one ring-shaped permanent magnet, then by magnetization pole of other one. ^ EFFECT: higher precision, higher efficiency, simplified maintenance. ^ 4 cl, 1 dwg
