Abstract: A wiper plug has a telescoping feature to allow it to be shorter while in a lubricator so as to reduce lubricator length as compared to an extended length for proper propulsion past off center openings such as side pocket mandrels in the string. The wiper has a telescoping feature that allows it to extend when dropping or being pumped from a lubricator. Once extended, it can lock in the extended position so that it doesn't collapse on the way down the string. Centralizers can optionally be used between an upper and a lower wiping section.

Abstract translation: 刮水器插头具有伸缩特征，以允许其在润滑器中更短，以便与延长的长度相比减小润滑器长度，用于适当的推进越过中心开口（例如弦中的侧口袋心轴）。 刮水器具有伸缩特征，允许其在从润滑器下落或被泵送时延伸。 一旦扩展，它可以锁定在扩展位置，使其不会在字符串下方折叠。 可以在上擦拭部分和下擦拭部分之间选择使用集中器。

Abstract: An energy storage device a first member and a second member that is slidably engaged with the first member. There are at least two seals that slidably seal the first member to the second member and define a cavity therebetween that varies in volume with relative movement between the first member and the second member. The first member is biased toward the second member in a direction that resisted increases in volume of the cavity.
