EXPANDABLE SCREEN WITH EXTERNAL CONDUIT

摘要

An expanding screen (10) with an associated sprirally wrapped exterior contr ol line (22) is disclosed. The control line rests in a spiral trough (24) made up in an exterior perforated jacket. The trough can be made by a pair of ridges (26) disposed substantially parallel to each other or by an ordered spacing of raised dimples in the outer perforated jacket to create spiral troughs. At t he screen connections centalizers (18) having a spiral path or paths within can serve a dual function of locating the screen prior to a expansion and protecting the control line in the joint area. A fiber optic cable can be placed in the control line.
