Embodiment Construction

[0032] Reference to the drawings is for the purpose of describing the preferred embodiments only and not for the purpose of limiting the embodiments. figure 1 Generally shown is a drum or reel 10 for supporting and / or transporting composite coiled tubing. The spool 10 is typically transported by truck, barge or ship, and is transported in bundles of the spool and coiled tube, often referred to as a coiled tube unit. figure 1 Composite tubing 18 is also shown being uncoiled and extended from coiled tubing unit 10 for processing, eg, concentrically lowered into a subterranean well for downhole operations. figure 2 generally expressed figure 1 Shown or is a cross-sectional view of the reel 10 with the composite conduit 18 removed for clarity. also, figure 2 Also shown are some components of a preferred embodiment, including flexible material 22 affixed to the outer surface of hub 20 .

[0033] In a preferred embodiment, the outer hub 20 is mounted on a base 14 and is rotata...

Abstract

This invention relates to two apparatus and one method for use in spooling composite coiled tubing onto a coiled tubing reel. One apparatus includes the modification of tubing reel cores currently in common use by the direct adhesion of a compliant material to the hub. Another apparatus modifies the commonly used tubing reel hub by affixing several panels concentric to the hub and mounted on compression springs. The method entails the pressurization of the composite coiled tubing prior to spooling onto the tubing reel, and subsequently releasing the pressure within the composite tubing after it has been spooled onto the tubing reel. Both apparatus and the method protect the reel core by absorbing or eliminating the radially inward forces of the composite tubing resulting from the pressurization and corresponding contraction in length of the spooled composite coiled tubing.

Description

technical field [0001] The present invention relates generally to spools for supporting and transporting coiled tubing, and more particularly to a pipe reel mandrel and method for winding composite coiled pipe onto a pipe reel mandrel. Background technique [0002] Coiled tubing has been used successfully in the oil and gas industry for many years. The development of new technologies has extended the role of coiled tubing to well completion, well workover, drilling and mining applications. The vast majority of technologies and applications focus on metal coiled tubing. Although the use of metal coiled tubing has increased significantly over the past two decades, there are several limitations in the use of metal tubing, including limitations in tensile strength due to pipeline weight and susceptibility to corrosion in harsh environments. [0003] Technological developments in coiled tubing products based on non-metallic composite materials have helped address many of the li...
