    Abstract: An inductive coupler apparatus have a first inductive coupler with a first magnetic center shaft having a recessed portion, a first outer magnetic layer disposed around the first magnetic center shaft, and a first coil disposed around the first magnetic center shaft and disposed within the first outer magnetic layer and a second inductive coupler with a second magnetic center shaft having a recessed portion, a second outer magnetic layer disposed around the second magnetic center shaft, and a second coil disposed around the second magnetic center shaft and disposed within the second outer magnetic layer. When the first and second inductive couplers are in the coupled position the inductive couplers can provide for the transmission of power and/or communication between downhole tools in a bottom hole assembly.

    Abstract translation: 感应耦合器装置具有第一电感耦合器，第一磁性中心轴具有凹部，围绕第一磁性中心轴设置的第一外部磁性层，以及围绕第一磁性中心轴布置并设置在第一外部磁心中的第一线圈 磁性层和具有凹部的第二磁性中心轴的第二感应耦合器，设置在第二磁性中心轴周围的第二外部磁性层，以及设置在第二磁性中心轴周围并设置在第二外部磁性层内的第二线圈 。 当第一和第二电感耦合器处于耦合位置时，感应耦合器可以提供底孔组件中井下工具之间的功率传输和/或通信。
