Abstract
An expandable tubular element for use in a wellbore formed in an earth formation, the tubular element comprising a first radially expandable tube a nd a second radially expandable tube. The tubes are arranged in a manner that a n end portion of the second tube extends into an end portion of the first tube , wherein a selected one of said end portions has a reduced resistance to radi al expansion per unit length compared to a remainder portion of the tube to whi ch the selected end portion pertains. These end portions may comprise slits (36 ), hinges (42), tubules (24) or folded sections (28).
Claims (14)
1. An expandable tubular element for use an a wellbore formed in an earth formation, the tubular element comprising a first radially expandable tube and a second radially expandable tube, said tubes being arranged in a manner that an end portion of the second tube extends into an end portion of the first tube, wherein a selected one of sand end portions has a reduced resistance to radial expansion per unit length compared to a remainder portion of the tube to which the selected end portion pertains, said end portion of reduced resistance to radial expansion including at least one section of reduced resistance to stretching in circumferential direction compared to said remainder portion of the tube, characterized in that said at least one section of reduced resistance to stretching includes a foldable member, the foldable member being arranged to deform between a folded state and an unfolded state upon radial expansion of the selected end portion.
2. The expandable tubular element of claim 7, wherein said end portion of reduced resistance to radial expansion is the end portion of the first tube.
3. The expandable tubular element of claim wherein said at least one section of reduced resistance to stretching includes a tubule extending substantially in longitudinal direction of the expandable tubular element, the tubule being arranged to deform upon radial expansion of the selected end portion.
4. The expandable tubular element of claim 3, wherein the tubule is arranged to deform from a relatively round shape to a relatively flat shape upon radial expansion of the selected end portion.
5. The expandable tubular element of claim 3, wherein the tubule is compressed in circumferential direction of said selected end portion, and wherein the tubule is arranged to deform from the compressed configuration to a less compressed configuration upon radial expansion of the selected end portion.
6. The expandable tubular element of any one of claims 3-5, wherein the tubule has a reduced resistance to radial expansion contains a fluidic seal compound, and wherein the tubule is provided with small openings arranged to allow flow of the seal compound in-between said end portions so as to form a seal between the end portions.
7. The expandable tubular element of any one of claims 3-6, wherein said selected end portion includes a plurality of said tubules spaced along the circumference of the selected end portion.
8. The expandable tubular member of claim 1, wherein the foldable member includes a folded wall section provided with at least one slit extending substantially parallel to an outer surface of the wall section so as to divide the wall section into a plurality of wall layers.
9. The expandable tubular member of claim 8, wherein said at least one slit extends along the full circumference of the selected end portion.
10. The expandable tubular element of claim 1 or 8, wherein the foldable member includes a wall section provided with at least one hinge.
11. The expandable tubular element of claim 9, wherein each hinge is a plastic hinge.
12. The expandable tubular element of any one of claims 111, wherein said end portion of reduced resistance to radial expansion is part of a muff which axially overlaps with a third tuba forming part of the tubular element.
13. The expandable tubular element of claim 12, wherein one of the first and second tubes extends into the muff at one side thereof, and the third tube extends into the muff at the ether side thereof.
14. The expandable tubular element substantially as described hereinbefore with reference to the drawings.
