    摘要: A method and apparatus is provided for drilling and lining a wellbore in one downhole trip. The method comprises mounting a drill bit on a drill string including a section of expandable tubing and providing a tubing expander in the string, then rotating the drill bit and advancing the drill string through a bore, then passing the expander through the expandable tubing to expand the tubing, wherein the expandable tubing is deformed by compressive plastic deformation of the tubing with a localised reduction in wall thickness, resulting in a subsequent increase in tubing diameter, and then retrieving the drill bit from the bore through the expanded tubing. The apparatus comprises a drill string including a section of expandable tubing, a drill bit mounted on the string, and a tubing expander mounted on the string, wherein the expandable tubing is deformed by compressive plastic deformation of the tubing with a localised reduction in wall thickness, resulting in a subsequent increase in tubing diameter and wherein the drill bit may be retrieved through the expanded tubing.

    摘要: There is disclosed an expandable seal for sealing at least part of a wall of a well borehole, an expandable seal assembly comprising at least two such expandable seals, and a method of sealing at least part of a well borehole using such a seal. In one embodiment, the expandable seal (32) comprises an expandable tubular support member (34) and an inflatable seal element (36) mounted externally of the expandable tubular support member (34) for inflation radially outwardly into sealing engagement with at least part of a wall (50) of a well borehole (10). There is also disclosed a sealing apparatus for sealing at least one flow port in an expandable downhole tubular, in one embodiment, the sealing apparatus (332) comprising a sealing member (384) coupled to an expandable tubular (334), the sealing member (384) including a deformable portion (387) movable between a closed position preventing fluid flow through a flow port (356) and an open position permitting fluid flow through the flow port (356).
