ABSTRACT:
A pre-packed well screen has concentric inner and outer fiber reinforced composite tubes with a granular filter medium in the annulus between the inner and outer tubes. The walls of the tubes are slotted for passing fluid through the slots and the filter medium. Each end of the inner tube extends beyond the adjacent end of the outer tube and has a male thread. A connection is made to an adjacent well screen or other tube by a female coupling member threaded onto the male thread. An advantage of the design is that the coupling member connected to the inner tube has an outside diameter approximately the same as the outside diameter of the outer tube.
