摘要： The present invention is a packer for sealing an annular region in a wellbore. The packer includes a packing element which is held through bidirectional forces. The packer first comprises an inner mandrel. Disposed around the inner mandrel are three tubulars: (1) a top sleeve; (2) a bottom sleeve; and (3) a booster sleeve. A packing element is disposed circumferentially around the outer surface of the booster sleeve. The top sleeve and bottom sleeve each include an upper compression member which rides across the booster sleeve in order to compress the packing element. The packing element is expanded outward from the packer to engage a surrounding string of casing through compressive forces provided by the top and bottom sleeves. Thereafter, differential pressure applied above or below the packer acting on the packer element and booster sleeve may provide additional compression of the packer element.

摘要： The present invention provides a connector arrangement for connecting and locking tubular members. The connector consists of two tubular members (100, 110) and a coupling member. The tubular members are threaded together to create a threaded connection. The locking arrangement is provided by a pathw ay (120, 130) formed on the tubular member whereby a locking member (500) can b e inserted in to the pathway to lock the threaded connection. The locking arrangement may also be provided by a plurality of castellation members (614 , 714) disposed on each tubular member. The connector may also have a separate coupling member (620) which has opposite right-hand (622R) and left-hand (622L) threaded ends to threadedly mate with the threads of the two tubular members.

GB2431675B Packer with metal sealing element 未知

摘要： A packer, and operation of the same, which forms elastomeric seals and non-elastomeric seals. The packer may be constructed from a non-elastomeric tubular core having a frustoconical shaped inner diameter. The outer diameter of the core may be substantially smooth and carry one or more elastomeric sealing elements. The packer is set by causing the diametrical expansion of the tubular core. The construction of the tubular core is preferably such that its diametrical expansion causes the formation of radial raised portions (upsets) on the outer surface. These raised portions form the non-elastomeric seals and also prevent extrusion of the elastomeric sealing elements.

摘要： Disclosed herein is a temporary well isolation device, which is sealingly disposable in downhole tubing, and which has a housing with an axial passage. The temporary well isolation device also has frangible barrier element within the housing, where the frangible barrier element is sealingly engaged in the passage blocking fluid flow through the passage. The frangible barrier element bears a load from fluid pressure. The temporary well isolation device also has a disengageable constraint in contact with a frangible barrier element so as to redirect the load on the frangible barrier element from a first component of the load to a second component of the load, thereby preventing rupture of the frangible barrier element. Also disclosed herein is a method for disintegrating a frangible barrier element disposed in a passage of a temporary well isolation device.
