    • An apparatus is described for controlling flow of fluid in a tubular positioned in a wellbore extending through a subterranean formation. A flow control system is placed in fluid communication with a main tubular. The flow control system has a flow ratio control system and a pathway dependent resistance system. The flow ratio control system has a first and second passageway, the production fluid flowing into the passageways with the ratio of fluid flow through the passageways related to the characteristic of the fluid flow. The pathway dependent resistance system includes a vortex chamber with a first and second inlet and an outlet, the first inlet of the pathway dependent resistance system in fluid communication with the first passageway of the fluid ratio control system and the second inlet in fluid communication with the second passageway of the fluid ratio control system. The first inlet is positioned to direct fluid into the vortex chamber such that it flows primarily tangentially into the vortex chamber, and the second inlet is positioned to direct fluid such that it flows primarily radially into the vortex chamber. Undesired fluids, such as natural gas or water, in an oil well, are directed, based on their relative characteristic, into the vortex primarily tangentially, thereby restricting fluid flow when the undesired fluid is present as a component of the production fluid.
    • 描述了一种用于控制位于穿过地下地层的井筒中的管中的流体流动的装置。 流量控制系统被放置成与主管道流体连通。 流量控制系统具有流量比控制系统和通路依赖电阻系统。 流量比控制系统具有第一和第二通道,生产流体流入通道,​​流体通过通道的流体与流体流动的特性相关。 所述依赖于路径的电阻系统包括具有第一和第二入口和出口的涡流室,所述通路依赖电阻系统的第一入口与流体比例控制系统的第一通道流体连通,并且与第二入口流体连通 流量比控制系统的第二通道。 第一入口被定位成将流体引导到涡流室中,使得其主要沿切向流动到涡流室中,并且第二入口被定位成引导流体,使得其主要径向流动到涡流室中。 油井中的不期望的流体(例如天然气或水)基于它们的相对特征被导向主要是切向的涡流,从而当不期望的流体作为生产流体的组分存在时限制流体流动。

    • A flow control system for use in a subterranean well can include a flow chamber through which a fluid composition flows, and a plug which is released in response to an increase in a ratio of undesired fluid to desired fluid in the fluid composition. Another flow control system can include a flow chamber through which a fluid composition flows, a plug, and a structure which supports the plug, but which releases the plug in response to degrading of the structure by the fluid composition. Yet another flow control system can include a flow chamber through which a fluid composition flows, and a plug which is released in response to an increase in a velocity of the fluid composition in the flow chamber.
    • 用于地下井的流量控制系统可以包括流体组合物流过的流动室和响应于不期望的流体与流体组合物中所需流体的比例增加而释放的塞子。 另一个流量控制系统可以包括流体组合物流过的流动室,塞子和支撑塞子的结构,但是响应于由流体组合物降低结构而释放塞子。 另一个流量控制系统可以包括流体组合物流过的流动室和响应于流动室中的流体组合物的速度增加而释放的塞子。
