IMPACTING BOTTOM AREA METHOD Russian patent published in 2018 - IPC E21B43/25 H01T9/00 

FIELD: mining.

SUBSTANCE: invention relates to means for generating seismic energy, for example, elastic vibrations in oil reservoirs, in particular to impact devices on the bottomhole well zone and oil saturated beds during hydrocarbon production. Method of impact on the bottomhole zone is that electrodes are installed in the interelectrode space. Then, a high-voltage pulse is applied to the electrodes, forming an electric arc between them and, thus, breakdown of the interelectrode gap and obtaining a plasma channel between the electrodes to form electrical discharges in the liquid medium of the well. In this case, the interelectrode space is ionized. Breakdown of the interelectrode space is made by high voltage pulses, repeated by signals of piezoelectric sensors. And the breakdown energy of the interelectrode gap is used to restore the ionized layer destroyed by the discharge. In this case, the pulses are fed in time with the oscillatory process that occurs in the well.

EFFECT: increased well flow rate at the production stage, providing the fastest and least labor-intensive output of the product to the maximum production and improved reliability of the system.
