    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 modular screen system allows connection of screens using couplings that connect the annular space in each module between the screen material and the base pipe. A series of connected screens and couplings feed into a single valve to control the flow through many screens. The valve is preferably located in a coupling and the passages through the coupling or the screen can also accommodate instrumentation to detect, store or transmit well data or flows through the various screen modules.

    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: 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 flapper type downhole valve is opened by flow against the flapper. The flapper and the housing contain magnets that hold the flapper open after it has been opened by flow to keep the flapper from chattering from the flow going past it. The strength of the force is not sufficient to hold the flapper open against a torsion spring on a pivot pin, when there is no flow through the valve. The valve can still be held in the locked open position with no flow through the housing by pressurizing the surrounding annulus to position another magnet to increase the holding force to a level greater than the force of the torsion spring. The additional magnet is spring biased so that upon removal of annulus pressure it shifts to allow the flapper to close. Alternative designs with and without a flow tube are possible. Fixed or movable restrictions can be associated with the flow tube to create a force to shift it to open a flapper with flow into the well.

    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. A setting mechanism connected to the slips is also located in the pocket. An actuator is mounted on the liner. As the liner is moved through the casing coupler, the actuator actuates the setting mechanism, causing the slips to move axially downward. As the setting mechanism moves downward, the slips move radially inward and grip the liner.

    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 swelling element rate regulation technique and product features an outer coating on a core of an element. The core is reactive to hydrocarbons or water depending on how it is configured. The surrounding coating is preferably formed of fine ground particles of a non-swelling polymer mixed in a solvent such as methyl-ethyl-ketone that is applied in a thin layer to the core exterior. This uncured outer layer is then contacted by a patterned surface. The patterned surface is pressed firmly against the uncured polymer/solvent mixture and transfers an inverse of the pattern to the surface of the coating. As pressure is applied, heat may also be applied to cure the coating. The resulting pattern is designed such that openings in the coating are created that regulate infiltration of water or other fluids through it and, as a result, the rate of swelling in the wellbore. Swell rate in governed in part by the ratio of the exposed area of the swelling compound to the total volume of the swelling compound. The smaller this ratio, the slower the rate of swell. The pattern created in the non-swelling layer may also provide limited mechanical restraint of the swelling element, further slowing the process.
