Abstract

A coiled tubing (CT) aligner for aligning a first CT string and a second CT string of a well system includes a first clamp having a central passage and positionable about the second CT string to apply a clamping force to the second CT string for locking the first clamp to the second CT string, a centralizer comprising a central passage in which the first CT string is slidably receivable, a rigid support arm connected between the first clamp and the centralizer, and a second clamp having a central passage and positionable about the first CT string to apply a clamping force to the first CT string for locking the first clamp to the first CT string.
