    摘要： Magnetorheological fluids, which solidify in response to a magnetic field, offer the ability to simplify many of the valves and control systems used downhole in the search for and production of oil and gas. They lessen the need for moving parts, provide solid-state valves, and can provide a differential movement of fluid through the valves by varying the strength of the magnetic field. Combinations of permanent and electro-magnets can improve safety by providing valves that fail, when power is lost, in either an open or closed position, depending on design. A number of examples are given.

    摘要： A navigation system for a downhole tool comprises a first sensor operable within a well bore to sense a parameter, at least one additional sensor, each of the at least one additional sensors being operable within the well bore to sense a parameter, and a locator component operable to determine a location of the downhole tool within the well bore based on the sensed parameters. A method for determining a location of a downhole tool within a well bore comprises deploying the downhole tool into the well bore, sensing a first parameter within the well bore via the tool, sensing at least a second parameter within the well bore via the tool, and self-determining the location of the tool based on the sensed parameters without receiving communications from the surface.

    摘要： An enhanced electrical power generating system. In a described embodiment, an electrical power generating system for use in a subterranean well includes a flow passage formed through a tubular string in the well, a flow region in communication with, and laterally offset relative to, the flow passage, an electrical power generator operative in response to flow of fluid through the flow region and multiple flow restrictors in the flow passage. The flow restrictors are operative to influence at least a portion of the fluid to flow from the flow passage through the flow region.

    摘要： A downhole tool (100) for wellbore operations comprises a substantially tubular member (130) that is operably positionable in the wellbore and a rotation member (110) that is rotatably disposed within the substantially tubular member (130). The rotation member (110) has a passageway (112) through which objects may pass into the wellbore. The rotation member (110) rotates about an axis of rotation (x) that is substantially perpendicular to the longitudinal axis (y) of the substantially tubular member (130) in response to fluid flow through the passageway (112). The rotation member (110) has magnetic properties such that rotation of the rotation member (110) generates a magnetic field that produces useable power.

    摘要： Remote operation of downhole tools in a subterranean wellbore is performed by inserting untethered, mobile devices sequentially into the wellbore. The mobile devices can include motive means, power supply, communication and data storage means, etc. In one embodiment, the method comprises maneuvering a first mobile device into proximity with a downhole tool, the device powering the tool. The first device is then removed, such as by flowing up or dissolving. The now-powered tool is used to perform a test or other operation. A second mobile device is maneuvered into proximity with the downhole tool and data is transferred. The second device is retrieved with the data or, using on-board logic devices, provides “if-then” commands to the downhole tool. Alternately, a third mobile device can be used to power and transfer commands to the tool. The method can be used for various tasks, such as opening bypass ports on ICD valves.

    摘要： Methods and apparatus are presented for a “disappearing” perforator gun assembly. In a preferred method of perforating a well casing, inserted into the well casing is a tubing conveyed perforator having an outer tubular made from a metallic glass alloy having high strength and low impact resistance. An inner structure is positioned within the outer tubular and holds one or more explosive charges. Upon detonating the explosive charges, the outer tubular is fragmented. The inner structure is preferably also substantially destroyed upon detonation of the one or more explosive charges. For example, the inner structure can be made from a combustible material, corrodible, dissolvable, etc., material. A disintegration-enhancing material is optionally positioned between the outer tubular and the inner structure. Additional embodiments are presented having gun housings which dematerialize upon detonation of the charges.
