    • A power system includes a rotary compressor. The power system may also include one or more power sources drivingly connected to the rotary compressor, the one or more power sources not including a turbine. Additionally, the power system may include a turbine, the turbine being free to rotate independently of the rotary compressor. The power system may also include power-system controls operable to cause the rotary compressor to generate a gas flow by causing the one or more power sources to rotate the rotary compressor. Additionally, the power system may be operable to direct at least a portion of the gas flow generated by the rotary compressor through the turbine to rotate the turbine.
    • 电力系统包括旋转式压缩机。 电力系统还可以包括驱动地连接到旋转压缩机的一个或多个电源,所述一个或多个电源不包括涡轮机。 另外,电力系统可以包括涡轮机,涡轮机独立于旋转压缩机自由旋转。 电力系统还可以包括电力系统控制,其可操作以通过使一个或多个电源旋转旋转压缩机来使旋转式压缩机产生气流。 另外,电力系统可以可操作地引导由旋转压缩机产生的气流的至少一部分通过涡轮以使涡轮旋转。

    • A controlled leakage seal assembly having a first stationary portion adapted to be connected in substantially fluid-tight relation to a source of drilling fluid and a second portion adapted to be connected in substantially fluid-tight relation to a rotary portion including a washpipe. The seal includes a first housing and a stack of radially inwardly extending, spaced apart annular stators, and a second seal housing and stack of spaced apart radially outwardly extending annular rotors. The stators and rotors are interleaved with one another and axially spaced apart by a working clearance. The stators and said rotors combine to define an elongated radially and axially extending tortuous path. The seal assembly permits the washpipe and the first and second housings to rotate relative to each other in substantially fluid-tight relation except for the drilling fluid passing along the tortuous path between the rotors and stators and allows the drilling fluid to enter an outlet region at greatly reduced pressure.
    • 一种受控的泄漏密封组件,其具有第一静止部分,该第一固定部分适于以基本上与流体密封的关系连接到钻井流体源,以及第二部分,其适于基本上与流体密封的关系连接到包括洗手水的旋转部分。 密封件包括第一壳体和径向向内延伸的间隔开的环形定子的堆叠,以及间隔开的径向向外延伸的环形转子的第二密封壳体和堆叠。 定子和转子彼此交错并且通过工作间隙轴向隔开。 定子和所述转子组合以限定细长的径向和轴向延伸的曲折路径。 密封组件允许洗涤管和第一和第二壳体以基本上流体密封的关系相对于彼此旋转,除了沿着转子和定子之间的曲折路径通过的钻井流体,并允许钻井流体进入出口区域 大大降低压力。
