摘要： The present invention provides means to extend the flow rate range over which a downhole turbine 70 will return a power output sufficient to meet the minimum downhole power requirements. In one embodiment, the present invention relates to an arrangement of axial vanes 77 that are situated such that the rotation of the rotor 76 generates an increasing drag force, thereby extending the upper limit of the flow rate range. In another embodiment, the present invention relates to an arrangement of restriction assemblies 75 that can be used to maximize the fluid velocity relative to the fluid flow rate past the stator 74 to achieve the necessary speed and power to rotate rotor 76, thereby extending the lower limit of the flow rate range. In another embodiment, the axial vanes 77 and restriction assemblies 75 are used in combination to further extend both the upper and lower limits of the flow rate range of the downhole turbine 70.
摘要翻译： 本发明提供了扩展流量范围的手段，通过该流量范围，井下涡轮70将返回足以满足最小井下功率要求的功率输出。 在一个实施例中，本发明涉及轴向叶片77的布置，其被设置为使得转子76的旋转产生增加的阻力，从而延长流量范围的上限。 在另一个实施例中，本发明涉及限制组件75的布置，其可用于使流体速度相对于通过定子74的流体流速最大化，以实现转动76所需的速度和动力，从而延伸下部 流量范围限制。 在另一个实施例中，轴向叶片77和限制组件75组合使用以进一步延长井下涡轮机70的流量范围的上限和下限。

摘要： An apparatus, system, and method for transmitting measurements while drilling are adapted for use with a drill string equipped with a mud motor. The drill string may comprise a plurality of interconnected drill pipe joints or a plurality of interconnected casing joints. The apparatus comprises a measurement-while-drilling tool adapted for placement in the drill string beneath the mud motor. The measurement-while-drilling tool has a system for transmitting telemetry signals, such as mud-pulse telemetry signals, upwardly through the mud motor and the drill string. In particular embodiments, the measurement-while-drilling tool has a system for transmitting mud-pulse telemetry signals upwardly through the mud motor and the drill string at frequencies below approximately 1 Hz, although other frequencies may be employed to advantage. The apparatus may further comprise a rotary steerable system for placement in the drill string beneath the mud motor. The rotary steerable system may be a point-the-bit system or a push-the-bit system. In particular embodiments, the rotary steerable system and the measurement-while-drilling tool are integrated.
