FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry, particularly, to well logging instruments. Downhole source of plasma-pulse action includes a housing, in which there is a control unit connected with electric energy accumulator, and plasma emitter connected to a mechanism for feeding metal conductor. Between electric energy accumulator and plasma emitter there is an electromechanical contactor-arrester comprising movable and fixed contacts. Fixed contact is connected with a high-voltage positive bus of electric energy accumulator, and movable contact with the help of flexible insulated conductor is connected to high-voltage electrode of plasma emitter.
EFFECT: higher reliability of well source of plasma-pulse action.
