摘要： The removable plug features a solid material that is housed in a porous container that has its shape changed to transition from the run in shape to the set shape. A swage is moved through a passage in the container to enlarge the passage and move the container to a borehole wall. The passage is then closed such as with a flapper valve or by moving in a mandrel into the expanded passage and lodging the mandrel in the expanded passage. Various release techniques are described.

摘要： The removable plug features a solid material that is housed in a porous container that has its shape changed to transition from the run in shape to the set shape. A running string and setting tool that creates relative movement deliver the plug and pull on its lower end while holding the top stationary against a backing plate. The container is pulled into itself as the radial dimension grows for the set. There can be a mandrel that remains in position and can lock to the backing plate or alternatively there can be no mandrel or a removable mandrel. The porous container can be removed in a variety of ways to let the solid material escape to be removed with fluid circulating in the wellbore. Alternatively the mandrel can be undermined to let the solid material escape for recovery.

摘要： A space filler material is used to prevent accumulation of debris that could later foul the operation of adjacent moving parts. In one application a void space that is subsequently closed by actuated parts is initially filled with a material that is highly compressible and has voids that allow it to compress without undue resistance to part movement when the void volume is reduced. Ideally, the pores or voids in the material itself are small enough to keep most if not all the debris from entering and making the space filling material too rigid to collapse under part movement. In an alternative application, the material can be in an annular space such as a seal bore and it can keep debris from getting past the seal bore while allowing hydrostatic pressure across itself thereby helping it to maintain its position until moved such as by shifting of an inner string to which it is attached.
摘要翻译： 使用空间填充材料来防止碎屑堆积，这可能会随后污染相邻移动部件的操作。 在一个应用中，随后由致动部件封闭的空隙空间最初填充有高度可压缩的材料，并且当空隙体积减小时具有允许其压缩而不会对零件移动的过度阻力的空隙。 理想地，材料本身中的孔或空隙足够小以保持大部分（即使不是全部）碎屑进入并使空间填充材料过于刚性而不能在部分运动下塌陷。 在替代应用中，材料可以在诸如密封孔的环形空间中，并且其可以使碎屑不会越过密封孔，同时允许横向自身的静水压力，从而帮助其保持其位置，直到移动，例如通过移动 它连接的内部字符串。

摘要： The method of the present invention deploys controlled electrolytic material, CEM, into the existing perforations to seal them and then using a bottom hole assembly, BHA, that isolates a portion of the wellbore to deliver a material that removes the CEM at a predetermined rate so that the BHA can be used to refracture the recently opened perforation. Additional new perforations can be made and fractured during the process.
