    • The present invention generally relates to controlling the flow of fluids in a wellbore. In one aspect, a valve for selectively closing a flow path through a wellbore in a first direction is provided. The valve includes a body and a piston surface formable across the flow path in the first direction. The piston surface is formed at an end of a shiftable member annularly disposed in the body. The valve further includes a flapper member, the flapper member closable to seal the flow path when the shiftable member moves from a first position to a second position due to fluid flow acting on the piston surface. In another aspect, a valve for selectively closing a flow path through a wellbore in a single direction is provided. In yet another aspect, a method for selectively closing a flow path through a wellbore in a first direction is provided.
    • 本发明一般涉及控制井眼中流体的流动。 在一个方面,提供了一种用于选择性地闭合沿着第一方向通过井筒的流动通道的阀。 该阀包括主体和可在第一方向上横跨流路形成的活塞表面。 活塞表面形成在环形地设置在主体中的可移动构件的端部。 阀还包括挡板构件,当可移动构件由于作用在活塞表面上的流体流动而从第一位置移动到第二位置时,挡板构件可关闭以密封流动路径。 在另一方面,提供一种用于选择性地闭合通过井筒沿单一方向的流路的阀。 在另一方面,提供一种用于选择性地闭合通过井筒沿第一方向的流动路径的方法。

    • The present invention generally relates to a method and an apparatus for placing fiber optic control line in a wellbore. In one aspect, a method for placing a line in a wellbore is provided. The method includes providing a tubular in the wellbore, the tubular having a first conduit operatively attached thereto, whereby the first conduit extends substantially the entire length of the tubular. The method further includes aligning the first conduit with a second conduit operatively attached to a downhole component and forming a hydraulic connection between the first conduit and the second conduit thereby completing a passageway therethrough. Additionally, the method includes urging the line through the passageway. In another aspect, a method for placing a control line in a wellbore is provided. In yet another aspect, an assembly for an intelligent well is provided.
    • 本发明一般涉及将光纤控制线放置在井眼中的方法和装置。 一方面,提供了将管线放置在井眼中的方法。 该方法包括在井眼中提供管状物,管状物具有可操作地连接到其上的第一导管,由此第一管道基本上在管状物的整个长度上延伸。 该方法还包括使第一管道与可操作地附接到井下部件的第二管道对准并且在第一管道和第二管道之间形成液压连接,从而完成通过其中的通道。 此外,该方法包括将线路推动通过通道。 另一方面,提供了一种将控制线放置在井眼中的方法。 在另一方面,提供了一种用于智能井的组件。
