FIELD: oil and gas industry.
SUBSTANCE: group of inventions relates to oil production from the production wells fitted with rod deep well pumps. According to the method on the pipe of the wellhead pack-off system located above the faceplate of the wellhead antigushing equipment or on the polished wellhead rod connected with a string of pump bars the vibroacoustic radiator is fixed together with the elastic uncoupler. The elastic uncoupler is a spring between the spreader bar of the rope suspension bracket and the polished wellhead rod. By means of this uncoupler the transfer of oscillations to the pumping unit is decreased. The vibroacoustic radiator is a low-sound radiator with a wide resonant band. Vibroacoustic oscillations are transferred to the string of pump bars, tubing, a production string and asphaltic and paraffin deposits. The output mechanical resistance of the vibroacoustic radiator is matched with time variable complex mechanical resistance of the load. For this purpose the vibroacoustic radiator is fixed on the named pipe or the rod in arbitrary manner, and its working frequency, amplitude and shape of modulating signal are adjusted in a wide low-frequency range both in continuous, and in radio pulse modes at control of amplitude and speed of excited mechanical oscillations.
EFFECT: increase of overall performance of a production well.
