    • An apparatus and method for filling a defined space, such as an annulus around a production tubular within a wellbore, includes a compliant porous material. The compliant porous material can be compressed and maintained in a compressed state by incorporation of a deployment modifier, which may be a water-soluble or oil-soluble adhesive or biopolymer, used as an impregnant, a coating, or a casing. The production tubular can be positioned at a desired location and the compliant porous material exposed to a deployment modifier neutralizing agent, which then dissolves or otherwise prevents the deployment modifier from continuing to inhibit deployment. Thus, deployment can be delayed to an optimum time by preventing exposure of the deployment modifier to the deployment modifier neutralizing agent. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
    • 用于填充限定空间的装置和方法,例如在井筒内的生产管周围的环形空间,包括柔性多孔材料。 柔性多孔材料可以通过结合使用作为浸渍剂,涂层或套管的水溶性或油溶性粘合剂或生物聚合物的展开调节剂而被压缩并保持在压缩状态。 生产管状物可以位于期望的位置,并且顺应性多孔材料暴露于部署改性剂中和剂,其然后溶解或以其他方式阻止部署改良剂继续阻止部署。 因此,通过防止部署改性剂暴露于部署改性剂中和剂,部署可以延迟到最佳时间。 要强调的是,该摘要被提供以符合要求摘要的规则,这将允许搜索者或其他读者快速确定技术公开的主题。 提交它的理解是,它不会用于解释或限制权利要求的范围或含义。

    • A shape memory polymer is initially fabricated to a size where its peripheral dimension will be at least as large as the borehole wall in which it is to be deployed. After the initial manufacturing the material temperature is elevated above the transition temperature and the material is stretched on a mandrel to retain its inside dimension as its outside dimension is reduced to size that will allow running the seal to a desired subterranean location without failing the material during the stretching. The material is allowed to cool below the transition temperature to hold the new shape. The material on the mandrel is then secured to a tubular string and delivered to the desired location. Wellbore fluid at given temperature raises the material again above the transition temperature, which causes the material to revert to its originally manufactured shape.
    • 形状记忆聚合物最初被制造成其周边尺寸至少与其展开的井壁一样大的尺寸。 在初始制造之后,材料温度升高到转变温度以上并且材料在心轴上被拉伸以保持其内部尺寸,因为其外部尺寸被减小到允许将密封件运行到期望的地下位置的尺寸,而不会在期间使材料失效 拉伸。 允许材料冷却到转变温度以下以保持新的形状。 然后将心轴上的材料固定到管柱上并输送到期望的位置。 在给定温度下的井筒流体再次使材料升高到转变温度以上,这导致材料恢复到其原始制造的形状。

    • Filtration devices may include a shape-memory material having a compressed run-in position or shape and an original expanded position or shape. The shape-memory material may include an open cell porous rigid polyurethane foam material held in the compressed run-in position at the temperature below glass transition temperature (T9). The foam material in its compressed run-in position may be covered with a fluid-dissolvable polymeric film and/or a layer of fluid-degradable plastic. Once filtration devices are in place in downhole and are contacted by the fluid for a given amount of time at temperature, the devices may expand and totally conform to the borehole to prevent the production of undesirable solids from the formation.
    • 过滤装置可以包括具有压缩的入口位置或形状和原始扩展位置或形状的形状记忆材料。 形状记忆材料可以包括在低于玻璃化转变温度(T9)的温度下保持在压缩的输入位置的开孔多孔硬质聚氨酯泡沫材料。 处于其压缩进入位置的泡沫材料可以被可流体溶解的聚合物膜和/或一层可流体降解的塑料覆盖。 一旦过滤装置在井下就位并且在温度下被流体接触给定的时间,则装置可以膨胀并完全符合钻孔,以防止从地层产生不需要的固体。
