LOGGING WINCH COLLECTOR Russian patent published in 2006 - IPC E21B47/01 E21B47/12 

FIELD: well research, possible use during connection of logging cable to ground-based receiving-transmitting equipment.

SUBSTANCE: collector of logging winch consists of moveable part - rotor, including shaft connected to winch, mounted on which are, isolated from shaft and each other, metallic rings, along which brushes slide, connected to clamps, mounted in immobile section of collector - body, wires of geophysical ground-based equipment also being connected to aforementioned rings. Additionally introduced into rotor are clamps, resistors, capacitors, and module for wireless receipt-transmission of information, while wires of geophysical cable, first ends of resistors and inputs of receiving-transmitting module are connected to clamps. Second ends of resistors and first ends of capacitors are connected to rings of rotor, while second ends of capacitors are connected to common wire.

EFFECT: increased interference protection of information in receiving-transmitting routes of geophysical measuring systems, using digital telemetry.
