摘要： In one aspect an induction resistivity tool incorporated into a downhole tool string comprises an outer wall of a downhole component comprising an outer diameter and at least one induction transmitter assembly disposed along the outer diameter. The at least one transmitter assembly comprises at least one induction transmitter coil wound about at least one core. The at least one transmitter coil is adapted to project an induction signal outward from the outer wall when the at least one transmitter coil is carrying an electrical current. The transmitter assembly is adapted to create electromagnetic fields that originate the induction signal from outside the outer wall and substantially prevent the signal from entering the outer wall.

摘要： In one aspect of the present invention, an induction resistivity tool includes an induction transmitter and an induction receiver located along the length of the tool. The transmitter is located adjacent at least one induction bucking coils of the tool. When activated the bucking coils are configured to direct a field transmitted by the induction transmitter away from the tool at an angle from the central axis of the tool.
