FIELD: oil production with use of electric stimulation of oil formation. SUBSTANCE: plant consists of cased well and electrode installed in well on pipe string. Electrode is made in the form of pipes connected by couplings with centralizer, contactors and terminals. Cable conductors are connected to terminals. To extend zone of stimulation, grounding is used in the form of casing strings of several well which encircle the well in which electrode is installed. Cable is connected to DC source, and successive transmission of pulse maximum of rectified voltage is effected to contactors. Pipes used for formation of electrode may be manufactured from nonconductive material. EFFECT: higher efficiency of treatment due to pulse stimulation of formation with voltage waves and extended zone of treatment. 3 cl, 2 dwg
