摘要：
A tubing connection arrangement (10) comprises two expandable tubing sections (12, 14), each tubing section comprising a filter screen (16, 18) sandwiched between inner expandable tubing (20, 22) and outer expandable tubing (24, 26). The filter screen of one tubing section overlaps the filter screen of the other tubing section and the outer expandable tubing of at least one of the tubing sections extends over the overlapping filter screens. On expansion of the tubing sections, the overlapping filter screens, restrained by the outer tubing, ensure the integrity of the filter between the tubing sections.
