EXPANDABLE TUBULAR INSTALLATION SYSTEMS, METHODS AND APPARATUS

摘要

Systems, apparatus and well intervention methods are described. Tubular member radial expansion apparatus includes a support member having forward and rearward ends; a drive unit and an expansion member disposed on the support member providing force for propelling the expansion member through an expandable tubular and expanding it, the drive unit disposed rearward of the expansion member; front and rear anchors disposed on the support member for engaging the expandable tubular's ID to provide reaction forces to propagate the expansion member through the expandable tubular, the rear anchor positioned behind the drive unit and providing its reaction force after the front anchor has exited the expandable tubular; a casing lock disposed on the support member and positioned between the expansion member and the front anchor, securing the expandable tubular to the support member during running-in-hole (RIH); and a valve attached to the forward end of the expandable tubular.
