LIGHT BASED COMMUNICATION PORT FOR USE ON DOWNHOLE TOOLS

摘要

A wellbore measurement instrument includes a housing configured to move along an interior of a wellbore. At least one sensor configured to measure a wellbore parameter is disposed in the housing. A controller disposed in the housing. The controller including at least one of a data storage device and a device to control operation of the at least one sensor. A first optical communications port is disposed in a first aperture in the housing. The first optical communications port includes an electrically operated light source. The first aperture in the housing is sealingly closed by a port plug having an optically transparent window therein. The port plug is configured to resist entry of wellbore fluid into an interior of the housing.
