摘要： A liner hanger has a housing with a pocket disposed on an inner wall surface and a slip slidingly engaged within the pocket. The liner hanger housing is secured in the string of casing. Both a setting mechanism and a liner engagement member are connected to the slips and are also located in the pocket. A releasable latching mechanism maintains the slips in the run-in position until the releasable latching mechanism is actuated. As the liner is moved through the casing coupler, the liner engagement member engages the liner through frictional force to cause the setting mechanism to move with the liner so that the latching mechanism can be disengaged and the slips can move axially downward. As the setting mechanism moves downward, the slips move radially inward and grip the liner.

摘要： A wellbore tubular has openings in its wall. An outer sleeve has ridges on which openings are located so that they communicate with the tubular openings. The tubular can be expanded to plant the ridges against the formation while any space between the ridges and the borehole wall can be used for pumping cement without fouling the aligned openings between the tubular and the sleeve. Optionally the sleeve can swell with or without tubular expansion. The openings can be initially sealed for delivery to the desired location and then opened using well or added fluids or well conditions.

摘要： A sealing element that swells on exposure to well fluids present or added to the wellbore is assembled to the mandrel in a manner to induce circumferential stresses proximately to the inside diameter of the element so as to resist the tendency of the inside diameter of the element to grow during the swelling process. A vacuum and a pressure method are described. Leak paths between the mandrel and the sealing element are minimized or eliminated as a result.

摘要： Sealing devices for use in a wellbore to seal a leak path through an inner wall surface of the wellbore comprise a mandrel, an expandable element, and a shape deforming sealing element. Expansion or inflation of the expandable element moves the shape deforming sealing element from its run-in shape to its set shape. A stimulus, such as a change in temperature, acts upon the shape deforming sealing element facilitating the shape deforming sealing element changing shape. Removal of the stimulus causes the shape deforming sealing element to remain in the set shape. Thereafter, the mandrel and expandable element can be removed to leave only the shape deforming sealing element within the wellbore to seal the leak path.

摘要： Slip members for use with downhole tools comprise a body formed of a first or body material and one or more hard material elements formed of a second or element material. The element material is harder than the body material. The hard material element is disposed through the body and in communication with a first surface and a second surface of the body, the second surface being disposed opposing the first surface. During manufacturing of the slip members, the hard material element may extend outwardly from one or both of the first and second surfaces. After manufacturing, the hard material element can be shaped to provide a gripping member.

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.
