Abstract
A technique for connecting expandable tubulars. The technique comprises an expandable connector system that facilitates the connection of tubular components, such as tubulars used in wellbore environments.
Claims33
A system of expandable tubulars, comprising:
- a first expandable tubular;
- a second expandable tubular;
- and
- a connector system coupling the first expandable tubular to the second expandable tubular, the connector system having a plurality of interlocking extensions comprising receiving extensions and insertion extensions, each receiving extension having a connector opening with a narrow outer portion and a wider inner portion to interlockingly receive a corresponding insertion extension.
1 more element
A connector system for connecting a pair of adjacent tubulars, comprising:
- a plurality of connector portions extending from a first expandable tubular;
- and
- a plurality of corresponding connector portions disposed at an end of a second expandable tubular, the plurality of connector portions being configured to interlockingly receive the corresponding connector portions when the first expandable tubular and the second expandable tubular are rotated with respect to each other.
A system of expandable tubulars, comprising:
- a first expandable tubular;
- a second expandable tubular coupled to the first expandable tubular via a connector system;
- and
- a sand barrier disposed along the connector system.
1 more element
A system of expandable tubulars, comprising:
- a first expandable tubular;
- a second expandable tubular;
- and
- a slide cover mounted on the first expandable tubular, wherein the slide cover may be slid into engagement with the second expandable tubular to secure the second expandable tubular to the first expandable tubular.
1 more element
A system for connecting tubulars, comprising:
- a first tubular;
- a second tubular;
- and
- a connector system coupling the first tubular to the second tubular, the first tubular having a plurality of receiving extensions and the second tubular having a plurality of insertion extensions, each receiving extension being configured to interlockingly receive a corresponding insertion extension, wherein the outside diameter of the connector system does not exceed the outside diameter of either the first tubular or the second tubular.
