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： 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： Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a seat disposed within the bore. The seat has a first position when the apparatus is in the run-in position and a second position when the apparatus is in the set position. The seat comprises an arcuate member comprising a plurality of slits defining a plurality of segment members having a gap there-between. Each of the gaps are variable such that movement of segment members inwardly causes the gaps to be narrowed or closed off completely when a plug element is disposed into the bore and landed on the arcuate member to move the arcuate member from the first position to the second position, causing restriction of fluid flow through the bore and the well conduit.
摘要翻译： 用于限制流体通过井管道的流体的装置包括具有纵向孔和设置在孔内的座的壳体。 当装置处于入位位置时，座椅具有第一位置，当装置处于设定位置时，座椅具有第二位置。 所述座椅包括弓形构件，所述弓形构件包括多个狭缝，所述多个狭缝限定在其间具有间隙的多个段构件。 每个间隙是可变的，使得当栓塞元件设置在孔中并落在弓形构件上以使弓形构件从第一位置移动到第二位置时，段构件的运动向内使间隙变窄或完全闭合 位置，导致通过孔和井管的流体流动的限制。
