    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: 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.
