Abstract
Multiple sintered metal sand screen sections are mechanically coupled to a perforated screen mandrel in an arrangement which is capable of sustaining normal bending loads associated with run-in in highly deviated and horizontal well bores, without breaking the mechanical connections or otherwise damaging or impairing the structural integrity of the sintered metal screen sections. The multiple screen sections are held under compression by end collars. Adjacent screen sections are separated by annular spacing rings and by resilient seal rings which seal the union between adjacent end portions of the sintered metal screen sections. The end collars are welded directly onto the screen mandrel, with the sintered metal screen sections being stabilized about the perforated mandrel by longitudinal compression loading, so that it is not necessary to form a weld joint on the sintered metal material. Bending stress which would otherwise be imposed on the sintered metal screen sections is relieved by flexure of the resilient seal ring elements.
