    摘要: A downhole element to isolate or complete a wellbore includes a shape memory material including polyphenylene sulfide. The polyphenylene sulfide is the cure product of being cured at a temperature of about 200° C. to about 400° C., for a total time of less than or equal to 200 hours. The shape memory material is thermally activated between an actuated and unactuated shape, and the polyphenylene sulfide in the shape memory material is a closed cell foam, open cell foam, or solid.

    摘要: 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 (Tg). 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.

    摘要: A driving device for a scanner includes an elongate guiding unit mounted in a base and disposed under an image sensor carriage that extends in a first direction, extending along a second direction transverse to the first direction, and having first and second side rail surfaces transverse to a top rail surface. A roller unit is mounted rotatably on a bottom side of the image sensor carriage, and includes a first roller rotatable about a first axis parallel to the first direction and disposed to roll along the top rail surface, and a second roller rotatable about a second axis transverse to the first and second directions and disposed to roll along the first side rail surface. A spring-loaded retaining unit is mounted on the image sensor carriage, and is disposed to contact rotatablely the second side rail surface. A driving unit drives the image sensor carriage to move in the second direction in the base.
