阅读说明：本技术 改进的隔离屏障 (Improved isolation barrier ) 是由 C·H·瑞克 W·L·麦克利戈特 P·H·图雷尔 C·B·K·考克里尔 于 2019-03-29 设计创作，主要内容包括：一种组合件和一种制造用作隔离屏障的组合件的方法,所述组合件在井中行进并固定在所述井内。所述组合件具有定位在管状主体的外部的套筒构件、固定在每个末端处,从而在其间形成腔室。流体能通过所述管状主体中的端口进入所述腔室,以使所述套筒构件抵靠所述井中较大直径的表面变形。所述套筒构件由至少两种材料形成,其在被布置在所述管状主体上之前被焊接在一起并被机械加工。一种材料比另一种材料可更易于膨胀,因此更容易变形。套筒通过螺纹和密封件连接到所述管状主体。所述套筒构件的初始构造在不影响所述管状主体或全部组合件的抗张强度的情况下允许焊接、检查和机械加工。(An assembly and a method of manufacturing an assembly for use as an isolation barrier, the assembly being run in a well and secured within the well. The assembly has a sleeve member positioned outside of the tubular body, secured at each end, forming a chamber therebetween. Fluid can enter the chamber through a port in the tubular body to deform the sleeve member against a larger diameter surface in the well. The sleeve member is formed of at least two materials that are welded together and machined prior to being disposed on the tubular body. One material may expand more easily and thus deform more easily than the other. The sleeve is connected to the tubular body by threads and a seal. The initial configuration of the sleeve member allows for welding, inspection and machining without affecting the tensile strength of the tubular body or the entire assembly.)
