摘要: A swellable packer device upon exposure to brine in a well. The device may be swellable to a substantially constant profile in spite of significant fluctuations in brine concentrations. Thus, the likelihood of packer failure due to under-swelling or over-swelling is reduced. Indeed, the packer may be employed for long-term operations or isolations ranging from a couple of weeks to twenty years or more without undue concern over packer failure from under or over swelling.

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。
