摘要: A wellbore device is provided which includes a fluid passage for transferring fluid between an earth formation and a surface facility, and a body transferable from a first mode to a second mode upon contact of the body with a selected fluid. The body is arranged so as to substantially close the fluid passage upon transfer of the body from the first mode to the second mode due to contact of the body with the selected fluid.

摘要: Tubular ends are heated to a predetermined temperature above 1200 degrees Celsius and surrounded by a shield gas when the tubular ends are pressed together to form forge welded tubular ends. The forge welded tubular ends are then cooled down rapidly from said temperature above 1200 to at most 600 degrees Celsius within 3 minutes after the forge welding operation.

摘要: A method of joining expandable tubulars includes joining the tubulars by forge welding and flushing a reducing flushing gas around the heated tubular ends during at least part of the forge welding operation such that oxides are removed from the forge welded tubular ends and the amount of irregularities between the forge welded tubular ends is limited.
摘要翻译: 连接可膨胀管的方法包括通过在至少部分锻造焊接操作期间通过锻造焊接和冲洗围绕加热的管状端部的还原冲洗气体来连接管子,使得氧化物从锻造焊接的管状端部移除,并且, 锻造焊接的管状端部受到限制。
