Abstract
A coiled tubing assembly for use in a wellbore includes at least two continuous coiled tubing members which are joined by clamp assemblies at longitudinally spaced positions such that the tubing members are adapted to be collectively spoolable on a common drum. Each clamp assembly has a central portion spanning between the spaced apart coiled tubing members and clamping portions joined to the central portion to extend about the tubing members respectively. Each clamping portion is maintained in an elastically stretched state in a circumferential direction about the respective tubing member such that the internal circumference of the clamping portion is arranged to be elastically reduced about the respective tubing member when the tubing member stretches longitudinally in use within a wellbore.
Claims31
A coiled tubing assembly arranged for use in a wellbore, the tubing assembly comprising:
- at least two continuous coiled tubing members, each defining a respective conduit extending in a longitudinal direction and arranged to receive wellbore fluids longitudinally therethrough;
- and
- a plurality clamp assemblies connecting the tubing members to one another at respective clamping locations spaced apart from one another in the longitudinal direction such that:
- the tubing members extend alongside one another in a parallel configuration;
- and
- the tubing members and the clamp assemblies thereon are adapted to be collectively spoolable on a common spooling member.
A method of preparing a coiled tubing assembly for use in a wellbore, the method comprising:
- providing at least two independent, continuous coiled tubing members, each defining a respective conduit extending in a longitudinal direction so as to be arranged to receive wellbore fluids longitudinally therethrough;
- providing a plurality clamp assemblies connecting the tubing members to one another at respective clamping locations spaced apart from one another in the longitudinal direction such that the tubing members extend alongside one another in a parallel configuration;
- and
- providing a common drum upon which said at least two independent, continuous coiled tubing members and the clamp assemblies thereon are collectively spooled.
