    摘要: In one aspect of the present invention, an induction resistivity tool incorporated into a downhole tool string component comprises an annular radial recess disposed along an outside surface of a tubular wall of the downhole component. At least one electrically insulated induction coil is disposed in the radial recess and adapted to transceive induction signals outward from the tubular wall when carrying an electrical current. The at least one coil is tuned for an optimal signal frequency and an actuator in the downhole component is adapted to put an electrically conductive element into and out of electrical contact with the at least one coil and thereby change the optimal signal frequency.

    摘要: An apparatus for installing data transmission hardware in downhole tools includes an insert insertable into the box end or pin end of drill tool, such as a section of drill pipe. The insert typically includes a mount portion and a slide portion. A data transmission element is mounted in the slide portion of the insert. A biasing element is installed between the mount portion and the slide portion and is configured to create a bias between the slide portion and the mount portion. This biasing element is configured to compensate for varying tolerances encountered in different types of downhole tools. In selected embodiments, the biasing element is an elastomeric material, a spring, compressed gas, or a combination thereof.
