摘要： Provided is a sealing/anchoring tool, a well system and a method for sealing/anchoring within a wellbore. The sealing/anchoring tool, in one aspect, includes a mandrel and a hydraulically deformable member positioned about the mandrel. The sealing/anchoring tool, in accordance with this aspect, further includes a sealing/anchoring element positioned about the hydraulically deformable member, the sealing/anchoring element including a circlet having an inside surface having an inside diameter (di), an outside surface having an outside diameter (do), a width (w), and a wall thickness (t), the circlet comprising an expandable metal configured to expand in response to hydrolysis to chemically deform the circlet from a radially reduced chemical state to a radially enlarged chemical state.

摘要： An inflow control device (ICD) that may include a piston located in a flow passage, a barrier that prevents fluid flow through the ICD, and a shear device that prevents movement of the piston. A method of actuating one or more ICDs may include preventing actuation of the devices by maintaining a pressure in an interior of a well tool (or tubing string) below an actuation pressure of the devices, where each device may include a piston located within a flow passage, a barrier that prevents fluid flow through the ICD, and a shear device that initially prevents movement of the piston. The method may include increasing the pressure in the well tool (or tubing string) to be greater than or equal to the actuation pressure, thereby shearing the shear device and moving the piston.

摘要： A shifting sleeve tieback seal system may include a body portion and a swellable material disposed about a circumference of the body portion. The swellable material is configured to expand in response to exposure to wellbore fluids. Further, the system may include an upper end ring disposed in a position axially above the swellable material, a lower end ring disposed in a position axially below the swellable material, and a sleeve disposed radially outward from the swellable material and sealed against the upper end ring and/or the lower end ring in a run-in position to isolate the swellable material from wellbore fluids. The sleeve is configured to contact a downhole feature in a setting position and contact with the downhole feature is configured to move the sleeve to expose the swellable material to wellbore fluids such that the swellable material expands to seal against a downhole tubular.

摘要： Provided is a support structure and a method for manufacture thereof. The support structure, in one aspect, includes first and second expanded metal structural pillars positioned within the ground by a distance (d1), the first and second expanded metal structural pillars comprising a metal that has expanded in response to hydrolysis. In at least one other aspect, the support structure includes one or more beams spanning the first and second expanded metal structural pillars.

摘要： A downhole sealing tool and method use a swellable material (e.g., a swellable rubber or a swellable metallic material) with increased surface area for faster reaction with an activation fluid. In one example, a swellable metallic sealing element and actuator are carried on a tool mandrel for lowering into a wellbore on a conveyance. The sealing element includes a plurality of expandable metal wires supported along the tool mandrel. The expandable metal wires comprise a swellable metallic material that swells in response to exposure to an activation fluid. The actuator is used to separate at least a portion of the expandable metal wires, to increase a surface area exposed to the activation fluid and thereby accelerate the reaction.

摘要： A well screen can include a shunt flow path, and an erosion resistant layer between the shunt flow path and a body, the erosion resistant layer comprising a coating applied to the body. A method of constructing a well screen can include constructing a shunt flow path having an erosion resistant layer therein, and positioning the shunt flow path with the well screen, whereby the shunt flow path can convey the erosive slurry between opposite ends of the well screen. A system for use with a well can include a well screen including a shunt flow path through which an erosive slurry flows between sections of an annulus external to the well screen, and an internal erosion resistant layer in the shunt flow path.
