    摘要： A method of deploying an apparatus in a wellbore comprises positioning a device at a predetermined location; wherein the device comprises a composition that contains an expandable graphite, and a metallic binder, and wherein the composition has a first shape; and exposing the composition to a microwave energy to cause the composition to attain a second shape different from the first shape. Alternatively, the composition further comprises an activation material comprising a thermite, a mixture of Al and Ni, or a combination comprising at least one of the foregoing and a method of deploying an apparatus comprising such a composition includes exposing the composition to a selected form of energy.

    摘要： A swelling element on a packer has a trough formed on a longitudinal axis. The control line or cable or conduit that needs to run along the string where the packer is mounted is first wrapped in a preferably non-swelling underlayment that can be a loose scroll or have its seam sealed. A swelling cover is placed over the underlayment using a seam that can be longitudinal or spiral to allow rapid deployment. The covering assembly for the control line or conduit is placed in the slot of the swelling element of the packer. The line or cable continues out opposed ends and can be secured to the tubular string with clamps. The control line can be covered with a swelling material and forced into a groove that runs the length of the packer swelling element.

    摘要： Downhole tools comprise a housing chamber with an expandable member disposed therein. An interior of the expandable member is in fluid communication with an outside environment so that hydrostatic pressure can act on an inner wall surface of the expandable member. The outer wall surface of the expandable member partially defines a sealed chamber within the housing chamber such that expansion of the expandable member due to an increase in hydrostatic pressure causes the volume within the sealed chamber to decrease, thereby energizing the sealed chamber. Thus, an increase in hydrostatic pressure within an outside environment is compensated. Further, when the hydrostatic pressure within the outside environment decreases, the energized sealed chamber causes contraction of the expandable member, thereby compensating for the decrease in hydrostatic pressure.

    摘要翻译： 井下工具包括其中布置有可扩张构件的容纳室。 可膨胀构件的内部与外部环境流体连通，使得静水压力可以作用在可膨胀构件的内壁表面上。 可膨胀构件的外壁表面部分地限定在容纳室内的密封室，使得可膨胀构件由于静水压力的增加而的膨胀导致密封室内的体积减小，从而使密封室通电。 因此，可以补偿外部环境中的静水压力的增加。 此外，当外部环境中的静水压力降低时，通电的密封室引起可膨胀构件的收缩，从而补偿静水压力的降低。

    摘要： An inflatable features a swelling layer. The swelling layer can be made integral or attached to the element or it can be bonded or otherwise secured to the mandrel. Upon inflation with fluid, the element expands into sealing contact with a surrounding tubular or wellbore. The fluid is absorbed or otherwise interacts with the swelling layer so that, in a preferred embodiment, the total occupied volume of the swelling layer and fluid individually is retained after mixing with the swelling of the layer acting to hold the seal of the inflatable element even if a problem develops in the sealing element.

    摘要： Setting mechanisms for downhole tools are described that take advantage of hydrostatic pressure in the wellbore which is harnessed to set a tool after exposure to well fluids for a given time or temperature defeats a lock and allows hydrostatic forces to trigger the setting of the tool. Alternatively, some other biasing source is released to set the downhole tool after exposure to well fluids for a time or a temperature and time defeats a lock and allows the biasing source to set the tool. While applications to packers are preferred, other downhole tools can be set in his manner removing the need for an inner string, dropping a ball on a seat or pressurizing the wellbore to achieve the setting of the downhole tool.
