SPOOLABLE SWIVEL

摘要

A spoolable swivel, methods, and systems for coupling a first and second length of coiled tubing. The spoolable swivel can include an inner tubular element and an outer tubular element. The inner tubular element and the outer tubular element can both have dimpled distal ends and races on their proximal ends, defining one or more annular voids for swivel bearings.

1. A spoolable swivel for coupling a first and second length of coiled tubing comprising:
an inner tubular element having
a first distal end having a first distal surface,a first proximal end having a first proximal surface, anda first race disposed on the first proximal surface; and an outer tubular element having
a second proximal end having a second proximal surface,a second race disposed on the second proximal surface, anda second distal end having a second distal surface, wherein the first race aligns with the second race to define an annular void when the first proximal end of the inner tubular element is inserted into the second proximal end of the outer tubular element, and wherein a plurality of bearings are positioned within the annular void to provide a swiveling coupling between the inner tubular element and the outer tubular element.
