    摘要： A downhole tool string component having a tubular body having a bore with a central longitudinal axis. An electrical conductor assembly is disposed within the bore of the tubular component, the assembly having signal couplers at first and second ends adapted for a butt connection. Centering assemblies are disposed within each end of the bore and have a plurality of projections extending radially outward from at least a partial central ring disposed around a portion of each end of the electrical conductor assembly, at least one centering assembly comprising a radial opening in the central ring adapted to receive the electrical conductor assembly. The first and second ends of the electrical conductor assembly are substantially aligned to the central axis of the bore at each end by the centering assemblies, the centering assemblies being adapted to allow fluid to pass through the bore.

    摘要： In one aspects of the present invention, an induction resistivity tool incorporated into a downhole tool string comprises a downhole tool string component comprising a mid-body intermediate first and second tool joints adapted for connection to adjacent tool string components. The mid-body comprises a central bore formed within a tubular wall of the component, the tubular wall comprising an inner and outer diameter. At least one annular radial recess is formed in the outer diameter of the mid-body and comprises a coil adapted to transceive induction signals outwardly from the mid-body, and at least one flexible ring of magnetically conducting material is disposed intermediate the coil and a surface of the recess and arranged within the annular radial recess such that it filters a range of frequencies of the induction signals.

    摘要： A system for communicating with a downhole network integrated into a downhole drill string is disclosed in one aspect of the invention as including a data transmission coupler mounted to a downhole tool and adapted to transmit data across a tool joint. The data transmission coupler is also capable of transmitting data by emitting electromagnetic radiation. An antenna is focused at and positioned within sufficient range of the data transmission coupler to detect the electromagnetic radiation and receive the data. This data may then be transmitted to a receiver or other equipment. In certain embodiments, the antenna is located above ground level and may be mounted to a swivel, derrick, hoist system, kelly, or other structure. The antenna is ideally mounted to a structure which is out of the way of equipment and workers working on the drill string.
