DEVICE AND METHOD FOR HIGH-FREQUENCY HEATING OF DIELECTRIC LIQUID Russian patent published in 2013 - IPC H05B6/54 

FIELD: oil and gas industry.

SUBSTANCE: device for supply of electromagnetic energy to dielectric liquid includes dielectric liquid chamber (20). In the chamber there located are at least three parallel or coaxial electrode plates (401-409) for creation of actually similar quantity of electromagnetic energy per unit volume of dielectric liquid between neighbouring electrodes of plates. Electric conductors (416, 426) are connected electrically to electrode plates for creation of high-frequency electric field between neighbouring electrode plates. As per the first version, electrodes are connected in series, and as per the alternative version, electrodes are parallel connected. Dielectric liquid heating method involves introduction of dielectric liquid to the chamber, creation of corresponding high-frequency electric fields between adjacent electrodes so that at least two areas of high-frequency field are created through the specified measurement of the chamber.

EFFECT: maximising oil extraction from an oil well.
