REELED TUBING SUPPORT FOR DOWNHOLE EQUIPMENT MODULE

摘要

A system for the inspection of a well borehole and the formation around the borehole includes reeled tubing (24) at the lower end of which is mounted a fiberoptic telemetry module (31) which receives various sensor modules for transmissions of sensed information to the surface. The modular telemetry link and sensor include fluid passageways throughout so that fluid pumped from the surface down the tubing 24 to create a region of optically clear and/or acoustically homogenous fluid (52) passes through the passageways in the modular equipment and cools the circuits thereof.
