OIL WELL AND OIL WELL BORE OPERATIONAL METHOD Russian patent published in 2006 - IPC E21B43/12 E21B47/12 

FIELD: oil wells, particularly to transmit control signal and power signal over well bore during gaslift well operation.

SUBSTANCE: oil well comprises bore and electroconductive pipeline system. Time-variable signal is applied to one section of pipeline system. At least one electronic unit is electrically linked to pipeline system section above impedance coil concentrically arranged from outer part of the pipeline system section in immediate proximity thereto. The impedance coil is chosen so that the impedance coil works as series impedance on power supply frequencies and in frequency band of communication path for electric signal transmitted over above pipeline system section. Above electric signal is received in wireless way by electronic units to regulate operation of at least one electronic unit. Electronic units may be formed as pilot-controlled valves or sensors. Well may include a number of electronic units each adapted to generate and receive communication signals to establish communication with another electronic units in different well sections.

EFFECT: increased quality of well operation.
