摘要： A composition suitable for use in a packer element for a wellbore includes: a hydrocarbon-swellable polymer, the hydrocarbon-swellable polymer present in the composition in an amount between about 10 and 30 percent by weight; an oil-resistant polymer, the oil-resistant polymer present in the composition in an amount between about 10 and 30 percent by weight; and a hydrocarbon swelling agent, the hydrocarbon swelling agent present in the composition in an amount between about 15 and 60 percent by weight. A composition as described may have a good balance of the swelling properties of the hydrocarbon-swellable polymer and the mechanical properties of the oil-resistant polymer. These properties may be useful in a packer element for a wellbore.

摘要： A packer assembly comprises a tubular member and a packer system that circumferentially overlies the tubular member. The packer system includes end portions and a central portion disposed between the end portions. The central portion and the end portions are formed of material that swells when contacted with a swelling fluid. The central and end portions are constructed to swell upon contact with the swelling fluid so that the central portion swells to a diameter defined by a wall of the wellbore more rapidly than the end portions. In such a configuration, the central portion of the packer system can be fully swollen prior to the full swelling of the end portions.
摘要翻译：封隔器组件包括管状构件和围绕管状构件的封隔器系统。封隔器系统包括端部和设置在端部之间的中心部分。中心部分和端部由与溶胀流体接触时溶胀的材料形成。中心部分和末端部分被构造为在与膨胀流体接触时膨胀，使得中心部分比端部部分更快地膨胀到由井眼的壁限定的直径。在这种构造中，封隔器系统的中心部分可以在端部完全膨胀之前被完全溶胀。

摘要： An industrial roll includes: a substantially cylindrical metallic core; a rubber base layer that is adhered to and circumferentially overlies the core; a rubber top stock layer that circumferentially overlies the base layer; and a polyurethane coating that circumferentially overlies the top stock layer. In this configuration, the roll can provide improved abrasion-resistance, sheet release properties, and/or toughness compared to a roll with a rubber cover, but may provide these properties in a cover that is softer than a typical polyurethane cover.

摘要： A shoe press includes: a first member; a second member; a substantially cylindrical belt; and a processing unit. The first member has a convex pressing surface. The second member includes a shoe with a concave pressing surface substantially complimentary to the convex pressing surface. The second member further includes a pair of substantially circular head plates rotatably mounted on axially opposed ends thereof. The belt is fixed to, extends between, and is rotatable with the head plates such that a portion of the belt passes between the convex pressing surface and the concave pressing surface. The belt includes embedded therein a communications cable having a plurality of sensors configured to generate signals responsive to an operating parameter of the shoe press. The processing unit is in communication with the communications cable and processes signals generated by the sensors. Thus, signals generated by the sensors and processed by the processing unit represent conditions (particularly pressure, nip width, temperature, strain and stress) within the nip of the shoe press that can be displayed and understood by an operator.
