Abstract: 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.

Abstract translation: 形状记忆聚合物最初被制造成其外围尺寸将至少与其将被展开的钻孔壁一样大的尺寸。 在初始制造之后，材料温度升高到高于转变温度，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，而不会在材料失效的情况下 伸展。 允许材料在转变温度以下冷却以保持新的形状。 然后将心轴上的材料固定到管状柱并且被输送到期望的位置。 在给定温度下的井眼液体再次使材料高于转变温度，这导致材料回复到其最初制造的形状。
