摘要： An expandable downhole seal includes a sealing portion and a deflecting portion adapted to move axially relative to each other to effect radial displacement of the sealing portion, wherein at least one of the sealing portion and the deflecting portion includes a swelling material. In use, radial expansion of the downhole seal may be achieved by the radial displacement of the sealing portion in combination with swelling of the swellable material. A support member is provided to support the sealing portion and deflecting portion.

摘要： A steerable soil penetration system having a steerable penetration head, which compacts and does not cut away the surrounding soil and which is connected to an elongate flexible tubing such that the orientation of the penetration head can be varied relative to the tubing. The elongate tubing and/or a downhole hammer or tractor pushes the penetration head through the subsurface formation. Preferably the tubing is surrounded by a narrow annulus so that buckling of the tubing is inhibited and the tubing protects the pierced hole against caving in. Optionally the tubing is circumferentially expanded after completion of the piercing process thereby increasing the width of the pierced hole and providing a permanent hole lining
摘要翻译：可操纵的土壤穿透系统，其具有可转向的穿透头，其压紧并且不切除周围的土壤并且连接到细长的柔性管，使得穿透头的取向可以相对于管变化。细长管和/或井下锤或拖拉机将穿透头推动通过地下地层。优选地，管道被狭窄的环带包围，使得管道的弯曲被抑制，并且管道保护穿孔以防止塌陷。可选地，在穿孔过程完成之后，管道被周向地膨胀，从而增加穿孔的宽度并提供永久性孔衬

摘要： A method of expanding a tubular element is provided, the tubular element having a first portion to be expanded to a first inner diameter and a second portion to be expanded to a second inner diameter larger than the first inner diameter. The method comprising: a) arranging an expandable sleeve of selected wall thickness in said second tubular element portion; b) positioning an expander in the tubular element; c) operating the expander so as to expand said first tubular element portion to the first inner diameter, and operating the expander so as to expand the sleeve to an inner diameter substantially equal to the second inner diameter minus double the wall thickness of the sleeve; and d) retrieving the sleeve from the tubular element.

摘要： A method of creating a borehole in an earth formation is provided. The method involves the steps of drilling a section of the borehole and lowering an expandable tubular element into the borehole whereby a lower portion of the tubular element extends into the drilled borehole section, radially expanding the lower portion of the tubular element so as to form a casing in the drilled borehole section, and separating an upper portion of the tubular element from the lower portion so as to allow the separated upper portion to be moved relative to the lower portion.
摘要翻译：提供了一种在地层中产生钻孔的方法。该方法包括以下步骤：钻出钻孔的一部分并将可膨胀的管状元件降低到钻孔中，由此管状元件的下部延伸到钻孔中，径向地扩张管状元件的下部，从而形成并且将管状元件的上部与下部分离开，以便允许分离的上部相对于下部移动。
