    摘要： Zonal isolation tools and methods of using same are described. The zonal isolation tools include a wellbore sealing member expandable by fluid pressure to contact a wellbore over an initial contact area, an inflation valve open during expansion of the sealing member to the initial contact area and closed upon the fluid pressure reaching a predetermined setting, a vent between the sealing member and a wellbore annulus adapted to open after the inflation valve is closed, and a compressive load imparted to the sealing member via a linear piston to achieve a sealing point at the leading edge of the sealing member. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

    摘要翻译： 描述了区域隔离工具及其使用方法。 区域隔离工具包括可以通过流体压力膨胀以在初始接触区域上接触井眼的井眼密封构件，在密封构件膨胀到初始接触区域期间打开的充气阀并且在流体压力达到预定设定时闭合， 密封构件和适于在充气阀关闭之后打开的井筒环之间的通气，以及通过线性活塞施加到密封构件以在密封构件的前缘处实现密封点的压缩载荷。 该摘要允许搜索者或其他读者快速确定本公开的主题。 它不会用于解释或限制权利要求的范围或含义。 37 CFR 1.72（b）。

    摘要： The invention is a system and method used to seal between an open wellbore and a tubing by bringing the wellbore wall inwardly so as to enable sections of earth from the wellbore wall to create the required seal against the tubing. The earth sections that make up the seal can be created by collapsing the relevant parts of the wellbore wall inwardly or by causing the relevant parts of the wellbore wall to swell inwardly.

    摘要翻译： 本发明是一种系统和方法，用于通过将井筒壁向内引导来使开放的井筒和管道之间进行密封，以使来自井筒壁的地球部分能够产生针对管道的所需密封。 构成密封件的地面部分可以通过将井眼壁的相关部分向内折叠或通过使井眼壁的相关部分向内膨胀而产生。

    摘要： Techniques are provided for sealing a communication line within a device positioned in a wellbore. The communication line may be continuous and extends through a pass-through arranged generally longitudinally through the device. Swellable sealing material is positioned about and/or over the communication line which is placed in the pass-through of the device to form and maintain a secure seal once the device is submerged in a fluid that causes the swellable sealing material to expand.
