摘要： A technique facilitates utilization of a packer (34) in a borehole (32) or within other tubular structures. The packer may be constructed for mounting about a generally tubular base pipe (36). The packer generally comprises a metal sleeve (40) combined with extremities (44) located at each axial end of the metal sleeve. The metal sleeve (40) maintains a seal once expanded to a surrounding wellbore wall, e.g. a casing wall. For example, the metal sleeve (40) may be combined with an elastomer along its exterior, the elastomer sealing against the surrounding wellbore wall when the metal sleeve is radially expanded. Additionally, a device, e.g. a valve (62), is employed to control the pressures acting on the metal sleeve. For example, the device may be in the form of a valve operable (62) to control pressures acting on the metal sleeve (40) while miming-in-hole, during expansion of the metal sleeve, and after setting of the packer.

摘要： A technique facilitates use of a packer in a borehole or within other tubular structures. The packer may be constructed with a tubing, a metal sealing element mounted around the tubing, and a differential pressure valve system. The metal sealing element may be expanded under fluid pressure for sealing engagement with a surrounding wall surface. Additionally, the differential pressure valve system is placed in fluid communication with the interior of the metal sealing element and comprises a plurality of valves which operate automatically to increase pressure within the metal sealing element when certain pressure differentials occur. The differential pressure valve system enables the packer to hold against higher differential pressures and also may be constructed so the packer is less sensitive to thermal variations.

摘要： A device is provided for cementing a casing in a well bore. The device includes, on the well head side, a shutter disposed within the casing that controls opening and closing of at least one cementing aperture. The at least one cementing aperture makes an interior of the casing communicate with an annular space situated between an external face of the casing and an internal wall of the well. The device also includes, on the well bottom side, a packer having two expandable liners mounted along the external face of the casing and at least one communication passage between an exterior of the first external liner and the annular volume. The at least one communication passage is situated on the packer side orientated towards the well bottom.
