    摘要： The present invention relates generally to a cushioning device that is adapted to retain a flowable medium to provide a cushioning effect. The cushioning device has a cushioning member having a deformable bladder member defining a medium chamber and a flowable medium, such as a fluid, retained in the chamber. The cushioning member is adapted to be mounted onto an article to thereby provide a cushioning effect for a user. The cushioning device can optionally have a support element to provide an additional cushioning effect. The present invention also relates to a cushioned article that has a finger-held or finger-manipulated article on which the cushioning device is mounted to provide a comfortable finger grip for a user. The cushioned article is so formed that it can fit within the user's finger grip and that the inflated bladder member can be deformed by the user's fingers or fingertips.

    摘要： An insert for perforating a subterranean formation sealingly engages a port in a production casing run into a wellbore intersecting the formation. The insert has a core where in a first mode it prevents fluid passage through the insert, and a second mode where the core disengages from the insert upon a treatment fluid reaching a threshold pressure in the casing, and ejects from the insert as a projectile to initiate and contribute to the fracture and stimulation of the formation by the pressurized treatment fluid exiting the port. The insert has a chamber which is filled with a gel that prevents wellbore cement from setting and is covered by a perforated debris shield that permits the equalization of pressure between the chamber and the annulus between the casing and wellbore.

    摘要翻译： 用于穿孔地层的插入件密封地接合在生产套管中的入口穿过与地层相交的井筒中的端口。 插入件具有芯，其中在第一模式中，其防止流体通过插入件，以及第二模式，其中芯在处理流体在处理流体达到套管中的阈值压力时与插入件脱离，并且作为抛射体从插入件喷出 启动并通过离开端口的加压处理流体促进地层的破裂和刺激。 插入物具有填充有凝胶的室，其防止井筒水泥凝固并且被穿孔碎片屏蔽覆盖，所述穿孔碎片屏蔽允许室与壳体与井眼之间的环空间之间的压力平衡。
