FIELD: oil-and-gas industry.
SUBSTANCE: invention can be used for improvement of oil reservoir performances at various stages by bringing the direct effects on deposit of resilient mechanical oscillations of preset intensity and frequency. It increases the efficiency of mechanical effects and drive life and decreases the power consumption. Vibroexciter drive comprises housing with feed and discharge channels, reactive-type drive rotor made of cermet fitted on commutator-shaft running in bearings fitted on the drive housing, replaceable inserts from cermet provided with calibrated orifice in its axis and temporary plug with the seat for said insert.
EFFECT: commutator-shaft is driven by productive bed gas flow at rpm preset by calibrated orifice flow section made with allowance of gas well yield.
