SLIDE-ON INDUCTIVE COUPLER SYSTEM

摘要

A technique facilitates use of an inductive coupler assembly with casing, e.g. well casing. An inductive coupler is formed as a female inductive coupler with an inductive coil. The inductive coupler is constructed for sliding movement along an exterior of the casing so that it may ultimately be positioned and secured at a suitable location along the casing. The inductive coupler is designed for connection with an electrical device, e.g. a sensor. The inductive coupler facilitates the transfer of sensor data and/or power signals across the casing. Signal transfer across the casing is further enabled by a male inductive coupler positioned within the casing at a location which allows it to cooperate with the exterior, female inductive coupler.

1. A system for use in a well, comprising:
a well casing having an interior surface and an exterior surface; a male inductive coupler positioned at a desired interior location within the well casing along the interior surface, the male inductive coupler having:
a male inductive coupler body; anda male inductive coupler coil mounted in the male inductive coupler body; and a female inductive coupler sized to slide along the exterior surface and positioned at a desired exterior location external to the well casing along the exterior surface, the female inductive coupler having:
a female inductive coupler body; anda female inductive coupler coil mounted in the female inductive coupler body; the female inductive coupler coil being generally radially aligned with the male inductive coupler coil to enable inductive transfer of signals across the well casing.
