FIELD: physics.
SUBSTANCE: group of inventions relates to a device for generating a disturbance in a differential propagation mode of a radio frequency signal transmitted along a coaxial transmission line. Proposed device comprises outer conductor and inner conductor separated by dielectric material layer. Device comprises a first conductor; second conductor and connection means. At that, means of connection are suitable for formation of electrical connection between device and coaxial transmission line so that first conductor of device forms electric connection between external conductor of transmission line in front of device and external conductor of transmission line after device, and the second conductor of the device forms an electrical connection between the inner conductor of the transmission line in front of the device and the inner conductor of the transmission line downstream of the device. At that, in the presence of a radio-frequency signal along the coaxial transmission line, a violation is created in the differential signal propagation mode along the coaxial transmission line, which induces current in the outer conductor of the coaxial transmission line, and an electromagnetic field in the region surrounding the coaxial transmission line. Device is used to form an antenna for the system to facilitate the extraction of hydrocarbons by radio-frequency heating of hydrocarbons of high viscosity at the location place by means of said antenna.
EFFECT: technical result is higher efficiency of temperature range control in radial direction for maximization of oil mobility in rock and increase of well productivity.
