ELECTROMECHANICAL CONVERTER, DOWNHOLE EQUIPMENT AND METHOD OF EXTRACTION OF GASEOUS LIQUID Russian patent published in 2024 - IPC F04F1/20 

FIELD: pumping equipment.

SUBSTANCE: proposed group of inventions relates to the field of pumping equipment that provides pumping of a gas-containing liquid by exposing it to a medium released from the gas-containing liquid itself. To extract the gas-containing liquid, pumping and compressor pipes and at least one electromechanical converter are placed in the well. At least one oscillation concentrator waveguide is fixed at each of the two opposite ends of the latter, acting on a gaseous liquid from two opposite sides of the converter core. The position of the electromechanical transducer in the well is set using a protruding means available on oscillation concentrator waveguides in the zone of zero oscillation amplitude. The electromechanical converter is placed in the well above the saturation pressure level of the gas-containing liquid, electrical energy is supplied to the winding of its core and the gas dissolved in the gas-containing liquid is released to form a gas-liquid mixture and the gas-liquid mixture is lifted to the surface due to the lifting energy of the released gas and pressure at the bottom of the well.

EFFECT: technical result is to increase the amount of gas released from a unit volume of a gas-containing liquid, without significantly increasing the mass characteristics of the equipment used, ensuring reliable fastening and retention of the electromechanical converter inside the well in conditions of high-frequency vibrations; the proposed solution makes it possible to abandon equipment for supplying auxiliary fluids to the borehole space to extract a gas-containing liquid.
