    摘要: A self-contained power generator comprises a fuel source, a solid oxygen source capable of releasing oxygen when heated, an engine capable of generating power by combusting the fuel with the oxygen so as to produce exhaust gases, and an exhaust gas absorbent. The oxygen source and the exhaust gas absorbent are preferably combined. The oxygen source may comprise potassium superoxide in combination with sodium peroxide, potassium oxide, or calcium oxide The engine may be any known heat engine. Fuel is fed to the engine at a desired rate so as to generate power at a desired rate. Heat from said combustion is preferably applied to the oxygen source and heat may be exchanged between the exhaust gases and oxygen. The exhaust gases are preferably absorbed at substantially the same rate as the rate at which they are generated such that pressure in the generator does not increase.

    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: Thin flexible piezoelectric transducers are bonded to or imbedded into oilfield tubular members or structural members. The transducers may be used to telemeter data as acoustic waves through the members. By proper spacing of transducers and phasing of driving signals, the transmitted signals can be directionally enhanced or encoded to improve transmission efficiency. The transducers may be used for health monitoring of the tubular or structural members to detect cracks, delaminations, or other defects. The flexible transducers are very thin so that overall dimensions of tubular or structural members are essentially unchanged by incorporation of the transducers.

    摘要: Perforation structures which allow increased production of fluids from a well. The perforation structures direct the flow of fluids into the well in a direction having a component parallel to the axis of the well and/or having a component which does not pass through the central axis of the well. Perforations in a productive zone may be slanted downward relative to the central axis of the well. Perforations may be tangentially deviated away from the central axis of the well so that fluid flowing from the perforation has a direction somewhat tangential to the well casing and circular motion is generated in fluids in the well. Fluids flowing through such perforations experience less pressure drop at the perforations, increasing pressure in the well and providing more energy to flow fluids up the well.

    摘要: A downhole fluid flow control device (188) and method for minimizing erosion are disclosed. The downhole fluid flow control device (188) includes a downhole surface (190) subjectable to an erosive stress (196, 198) which may be a moving fluid or an erosive agent, for example. A shape memory alloy (192) is integrated with the downhole surface (190) in order to provide erosion resistance by reversibly transforming from an austenitic phase (194) to a martensitic phase (200) in response to the application of the erosive stress (196, 198). Further, the shape memory alloy (192) reversibly transforms from the martensitic phase (200) to the austenitic phase (192) in response to the presence of sufficient heat.

    摘要: An energy storage device for powering a downhole tool may be heated to an effective temperature to improve the operability of the energy storage device. The energy storage device may comprise, for example, a primary battery, a secondary battery, a fuel cell, a capacitor, or combinations thereof. The effective temperature to which the energy storage device is heated may be greater than an ambient temperature in the wellbore near the energy storage device. The energy storage device may be heated using various heat sources such as an ohmic resistive heater, a heat pump, an exothermic reaction, a power generator, a heat transfer medium, the energy storage device itself, a downhole tool, or combinations thereof. A thermal conductor may extend between the heat source and the energy storage device. Further, a thermal insulator may at least partially surround the heat source and the energy storage device.
