REELED TUBING SUPPORT FOR DOWNHOLE EQUIPMENT MODULE

摘要

A system for the inspection of a well borehole and the formation around the borehole. The system includes a sealed tubing at the lower end of which is mounted a fiberoptic telemetry module which receives various sensor modules for transmissions of sensed information to the surface. The modular telemetry link and sensor include fluid passageways through which fluid pumped from the surface down the sealed tubing may pass to create a region of optically clear and/or acoustically homogenous fluid in the borehole in the vicinity of the modular telemetry link and sensor. The passage of fluid through the passageways in the modular equipment may also serve to cool the circuits thereof.
