LIGHTWEIGHT, LOW COST STRUCTURE FOR FORMATION CONDUCTIVITY MEASURING INSTRUMENT

摘要

A well logging instrument includes an electrically conductive sonde mandrel. Al least one electrical sensor is affixed to an exterior of the mandrel. The sensor is configured to be attached to the mandrel by sliding along an exterior surface thereof. A pressure-sealing electrical feedthrough bulkhead makes electrical connection from the at least one sensor through a wall of the mandrel.
