摘要： An insulated tubular assembly includes jointed insulated tubing segments, all with inner and outer tubes concentrically disposed about in order to define a vacuum annulus in between and closed at both ends by annular bridges. Insulated tubing segment are provided with either male or female threads to threadably engage and form a joint directly with each other or through a coupling jointed to adjacent insulated tubing segments. An insulating sleeve held around such joint includes a first tubular shell adapted to cover at least part of one insulated tubular segment and a second tubular shell overlapping either internally or externally part of the first tubular shell, such that the second tubular shell extends axially about the threaded joint from one annular bridge to the adjacent one, with high tolerances on lengths of the insulated tubing segment extension extending beyond their respective annular bridges.

摘要： A device and method are provided for mitigating annular pressure buildup in a wellbore casing annulus of an oil or gas well. The device includes a tubular member including an outer side, a chamber secured around the outer side, the chamber having at least one flexible portion for varying the internal volume of the chamber, at least one reservoir capable of supplying a gas, and a pressure compensator connecting the reservoir and the chamber. The reservoir is able to feed the chamber volume with the gas via the pressure compensator.

摘要： Disclosed is a tubing component for the oil and gas industry. The tubing component includes an outer tube and an inner tube within the outer tube, said tubes being so configured to create a space between each other over a specified length. Each end of the inner tube is secured to the internal surface of the outer tube by a frustoconical fillet weld so that said space is leak-tight. The inner tube has a first internal diameter ID along a first length starting from each end of said tube, and a second, smaller internal diameter ID′ along a second length beyond the first length. The tubing component further includes a protective metallic layer extending at least over the fillet weld. Also disclosed is a method for producing this tubing component.
