    摘要: An induction resistivity tool incorporated into a downhole tool string comprises an outer wall of a downhole component having an outer surface, and at least one induction transmitter assembly disposed along the outer surface. The transmitter assembly includes at least one induction transmitter coil which is wound about one or more transmitter cores. The transmitter assembly is adapted to create electromagnetic fields that originate the induction signal from outside the outer wall while substantially preventing the induction signal from entering the outer wall.

    摘要: A downhole induction resistivity assembly that comprises a downhole tool string component. The tool string component comprises an induction transmitter. The transmitter is adapted to induce an induction field in the surrounding formation. A first induction receiver is spaced apart from the transmitter and is adapted to measure the induction field. A magnetic field generating mechanism is disposed adjacent on either or both sides of the transmitter and adapted to guide the transmitter's signal into the formation. A second induction receiver is disposed in close proximity to the magnetic field generating mechanism and is adapted to measure the magnetic field generated by the mechanism.

    摘要: In one aspect of the invention an induction resistivity tool incorporated into a downhole tool string comprises an outer wall of a downhole component having an outer diameter. At least one induction transmitter assembly is disposed along the outer diameter. The transmitter assembly comprises at least one coil array and at least one induction transmitter coil wound about at least one core. The coil array comprises a plurality of magnetic units and each unit comprising a magnetic field orientation. The magnetic field orientations accumulatively form a Halbach array with an augmented field side and a canceled field side of the array. The transmitter assembly generates an induction signal from outside the outer wall and substantially prevents the signal from entering the outer wall when the transmitter assembly is carrying an electrical current.
