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： An extrudable ball seat (36) is configured to be secured along a well tubing (34). The extrudable ball seat (36) comprises a larger diameter section (42) and a smaller diameter (44) section connected by a conical section (46). The conical section (46) has an internal seating surface (48) for receiving a corresponding element, e.g. a ball (52), in sealing engagement. The extrudable ball seat (36) facilitates controlled extrusion of the element following a pressure actuation procedure by providing the smaller diameter section (44) with sufficient ductility to enable extrusion of the element under an increased predetermined pressure. Additionally, the extrudable ball seat comprises at least one notch (56), e.g. a plurality of grooves (58), positioned to initiate crack propagation and thus extrusion of larger elements.
