摘要： Through the combination of at least two polymer families, and the optimization of other components, a rubber compound has been developed for use in downhole applications that will swell in water-based fluids. A cellulose component, such as carboxy methyl cellulose (CMC), is used together with an acrylate copolymer (AC) that can increase the swelling capacity of an acrylonitrile butadiene rubber (NBR) in water to over 1000%. The amount of swelling achieved depends on physical boundaries and limitations, the salinity of the water, and the temperature.

摘要： A sealing element that swells on exposure to well fluids present or added to the wellbore is assembled to the mandrel in a manner to induce circumferential stresses proximately to the inside diameter of the element so as to resist the tendency of the inside diameter of the element to grow during the swelling process. A vacuum and a pressure method are described. Leak paths between the mandrel and the sealing element are minimized or eliminated as a result.

摘要： A packer for downhole use responds to water containing fluids by swelling from its core. The core is preferably covered with an outer layer that preferably has a lower rate of diffusion and swelling than the core that it surrounds. Because of this arrangement, the packer can be delivered to the desired location before it is set by swelling of the core. The outer layer can also be responsive to water containing fluids by dissolving slowly to allow time to properly position the packer before the core swells to a sealing relationship with the surrounding tubular or the wellbore wall.
摘要翻译：用于井下使用的封隔器通过其核心的膨胀来响应含水流体。核心优选地被外层覆盖，外层优选地具有比其围绕的核心更低的扩散和溶胀速率。由于这种布置，封隔器可以在通过芯部的膨胀而被固定之前被输送到期望的位置。外层还可以通过缓慢溶解来响应含水流体，以允许时间适当地定位封隔器，然后核心膨胀到与周围的管状物或井筒壁的密封关系。
