    摘要: The present invention relates to a control system for selectively supplying electrical power in a remote environment. The system comprises a plurality of electrical circuits, each designed to operate over a unique frequency passband. Power transmitted within the frequency passband of a circuit is filtered through that circuit to power a corresponding remote device. One or more remote devices can be simultaneously powered by transmitting power within the frequency passbands of the corresponding circuits. It is advantageous to design relatively narrow passbands to accommodate a relatively large number of circuits and corresponding devices for remote operation and a triac, rectifier or other suitable turn-on gate can be incorporated into each circuit to effectively control the width of the frequency passband of each circuit. Alternatively, an operational amplifier could be used.

    摘要: Surface controlled subsurface control valves for use in wells and methods of controlling the same. In one embodiment, a valve includes a valve body, a bore closure assembly, a mechanical linkage, a drive assembly, and a control assembly. The valve body defines a bore for fluid to flow through when the bore closure assembly is in an open position. When the bore closure assembly is in its closed position, the bore closure assembly prevents fluid from flowing through the bore. The mechanical linkage is operatively connected to the bore closure assembly and to the drive assembly. The primary control assembly determines a force to apply to the mechanical linkage based on a present operating condition of the valve and causes the drive assembly to apply the determined force to the mechanical linkage. As a result, the mechanical linkage drives the bore closure assembly.

    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.
