摘要： An elastomeric-based device configured for use in high temperature downhole environments exceeding about 400° F. The device includes a carbon nanotube mesh configured to dissipate heat relative elastomeric portions thereof so as to provide temperature resistance. Thus, a majority of modulus strength of the elastomeric portions may be maintained along with device functionality even upon exposure to such temperatures. Further, the mesh may also be configured to mimic the modulus character of elastomeric portions to allow a cohesive compliance to the device as a whole. Thus, isolation packers and other expansive downhole devices may particularly benefit from such combined material configurations as detailed herein.
摘要翻译：一种被配置用于超过约400°F的高温井下环境中的基于弹性体的装置。该装置包括碳纳米管网，其被配置为散发热相对弹性体部分以便提供耐温性。因此，即使暴露在这样的温度下，弹性体部分的大部分模量强度也可以与器件功能一起保持。此外，网格还可以被配置为模拟弹性体部分的模数特征，以允许整体上与装置的内聚性一致。因此，隔离封隔器和其它膨胀的井下装置可能特别受益于如本文详细描述的这种组合的材料构造。

摘要： A hydraulic regulating mechanism for disposal in a well. The mechanism includes a degradable metal based element and a swellable component for hydraulic regulation. The mechanism is configured for ease of setting and removal by allowing degrading of the metal based element upon exposure of certain downhole conditions to trigger shrinking of the swellable component. Further, the swellable component may be initially set by exposure to downhole conditions as well. Ultimately, a mechanism is provided which may effectively regulate high pressure applications downhole and yet, as a practical matter, be removed via a displacement or drill out that may take less than 15 to 30 minutes to achieve.
