摘要： A threaded connection is provided. The threaded connection comprises: first and second tubular components. The first tubular component comprises: at a first end region a pin with an outer surface on which is formed a male thread; and an opposite second end region. The second tubular component comprises: at a first end region a box with an inner surface on which is formed a female thread; and an opposite second end region. The male thread is arranged to engage the female thread in a made-up configuration. A male electrical contact is provided on the outer surface of the first end region of the first tubular component and insulated from the first tubular component. A female electrical contact is provided on the inner surface of the first end region of the second tubular component and insulated from the second tubular component. A first conductor extends along the outer surface of the first tubular component, in communication with the male electrical contact, and insulated from the first tubular component. A second conductor extends along the second tubular component, in communication with the female electrical contact, and insulated from the second tubular component. The male and female electrical contacts are arranged to contact with each other in the made-up configuration. The male electrical contact has a width in an axial direction of the first tubular component and the female electrical contact has a width in an axial direction of the second tubular component. The width of the female electrical contact is smaller than the width of the male electrical contact, or vice versa.

摘要： A telemetry system and method for communicating information axially along a drill string (20) comprised of a drive train (78) supported within a housing (80). The system includes an axial conducting loop (22) formed by the drill string (20) for conducting an axial electrical signal embodying the information between a first axial position (48) and a second axial position (50) in the drill string (20), which axial conducting loop (22) extends between the first (48) and second (50) axial positions. A transmitter (170) transmits information to the axial conducting loop (22). The drive train includes a downhole end (24) which extends from and is located below the housing (80). At least one of the first (48) and second (50) axial positions is located in the downhole end (24). The method includes the step of conducting the axial electrical signal between the first (48) and second (50) axial positions through the axial conducting loop (22) which extends between the first (48) and second (50) axial positions.

摘要： A high-frequency data and/or power transmission system suitable for downhole use including signal/power couplers, transmission line segments and signal repeaters. Signals and power are/is transmitted between couplers and/or between couplers and repeaters by means of electromagnetic resonance coupling. In at least a portion of the system, the transmission line segments form parallel data paths and the repeaters provide crossover capability between the data/power paths, thereby significantly improving reliability. The invention also includes methods of transmitting data and/or distributing high-frequency power through a downhole transmission system including multiple data/power paths and multiple crossovers wherein a fault location in one data/power path is bypassed by routing data and/or power to a parallel data/power path by means of electromagnetic resonance coupling.
