    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.

    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。

    摘要： A dynamic inflatable sealing device for maintaining the pressure within an inflatable element at least substantially equal to the pressure in the annulus to maintain the inflatable element in a sealing position. The dynamic sealing device includes an inflatable element forming an internal chamber, the inflatable element expandable to sealing engagement with a wall, and a dynamic valve mechanism in operational connection between the internal chamber and exterior of the internal chamber substantially communicating the pressure external of the inflatable element to the internal chamber.
