    摘要: A support device for tubular equipment, such as a liner inside a well, and methods for using the support device, the support device including two elements attached to each other. The two elements are: a) a cylindrical sleeve, made of ductile metal and having an external diameter slightly less than an inner diameter of the well or of a casing inserted into the well; and b) a set of tabs made of hard metal, which are spaced apart from each other and integral with the cylindrical sleeve. The tabs extend downwards from the cylindrical sleeve and an outer wall of the tabs is fitted with a series of notched formations, such as teeth, whereas an inner wall of the tabs has a conical form, the apex of which is turned down.

    摘要: A method of sealing a well comprising introducing a plug axially into the well, with a mouth of the plug turned up and a bottom wall part turned down, the plug being positioned in the well at a desired depth, after which the plug is inflated by injecting a high-pressure liquid into it via its mouth so that a tubular wall part of the plug expands radially beyond its elastic limit and presses firmly and tightly against the wall of the well by a crimping effect, while its bottom wall part serves as a sealing partition, forming a tight barrier between lower and upper parts of the well that it separates, the plug having an internal axial mandrel that connects its mouth to its bottom wall, the mandrel being pierced with channels that allow injection of high-pressure liquid inside the plug via the mouth and channels.

    摘要: The present invention relates to a device for laying an expansible lining in a conduit. The device may include a patch having an initial diameter less than that of the conduit, and the patch may be configured to deform by radial expansion beyond an elastic limit to an expanded diameter such that it may contact a wall of the conduit. The device may also include an expander tool axially displaceable inside the patch, and the expander tool may be configured to cause the radial expansion of the patch to an expanded diameter. The device may also include a checking member mounted in proximity to the expander tool. A section of the checking member may be calibrated so that the checking member and the expander tool are capable of passing freely inside the patch when the patch is properly expanded, and the checking member and the expander tool are unable to pass inside the patch when the patch is improperly expanded.

    摘要: A radially deformable inflatable tubular sleeve for tubing or obturating a well (P) or a pipe. The sleeve includes a tube and a series of breakable restraining rings positioned along the tube. The rings are arranged so that each ring breaks one after the other in the longitudinal direction of the sleeve when the tube is inflated by an internal fluid under pressure. As a ring breaks, liquid (B) present in the well is moved progressively forward so as to prevent pockets forming on the outside of the tubing.

    摘要: A method of patching a well or a pipe by hydroforming a tubular metal patch. A tool provided with a pair of inflatable packers is inserted inside the patch. The pair of inflatable packers are axially spaced apart from each other by a distance that is substantially equal to the length of the patch. The tool is positioned inside the patch so that the packers are in register with the end portions of the patch. The assembly of the tool and the patch is axially inserted inside the well or the pipe, and positioned in register with the zone for patching. The packers are inflated to a high pressure, sufficient for radially expanding the end portions of the patch and pressing them in a leak-tight manner against the wall of the well or the pipe. The packers are subsequently deflated and the tool is withdrawn. The method is applicable to the oil industry.

    摘要: The invention relates to device for controlling an inflatable tool used to treat a well or pipeline. The device, which is inserted between the outlet of a fluid supply pipe and the tool, comprises: a chamber communicating with the exterior through a tube and with the tool via a pipeline; and a piston mounted in said chamber, which, under the force of a spring, normally occupies a first position in which it seals the outlet of the pipe, the aforementioned tube then communicating with the pipeline. The pipeline is provided with at least one spring-loaded check valve which allows the passage of the pressurised fluid from the chamber to the tool when the pressure upstream of the valve exceeds a predetermined threshold value, which prevents the passage of the fluid in the opposite direction.
