发明名称 MECHANICAL EXPANSION SYSTEM
摘要 Methods and apparatus enable expanding a tubular in a wellbore. The method and apparatus include running a bottom hole assembly (BHA) into a wellbore. The BHA is anchored to the wellbore and a portion of the BHA is released from the anchor. An expansion member is then pulled by a work string through the tubular thereby engaging the tubular with the wellbore. The work string is reconnected to the anchor and used to release the anchor. The BHA is then removed from the wellbore.
