WIRELESS POWER AND COMMUNICATIONS CROSS-BAR SWITCH

摘要

A petroleum well (20) for producing petroleum products that incorporates a system adapted to controllably route communications and/or electrical power having a time-varying current through a piping structure (30 and/or 40) in the well (20), and methods of producing petroleum products use such a well, are provided by the present invention. The system comprises a first induction choke (70 or 100), a second induction choke (70 or 100), and a controllable switch (90). The first induction choke (70 or 100) is located about a portion of a first branch (26) of the piping structure (30 and/or 40). The second induction choke (70 or 100) is located about a portion of a second branch (29) of the piping structure (30 and/or 40). The controllable switch (90) comprises two switch terminals. A first of the switch terminals is electrically connected to the piping structure (30 and/or 40) on a junction side (81) of the induction chokes (70 or 100). The first and second branches (26 and 29) of the piping structure (30 and/or 40) intersect on the junction side (81) of the induction chokes (70 or 100). A second of the switch terminals is electrically connected to the piping structure (30 and/or 40) on another side (82) of at least one of the induction chokes (70 or 100).
