摘要:
A well tubing valve is described, having a substantially tubular body connected in a tubular string and a rotational valve member having at least one aperture. The valve member, which may be a sleeve having a part spherical surface, is rotationally moveable relative to the body to align and misalign the aperture in the valve member with a port in the body. The valve member is actuable to rotate relative to the body in a single direction, and moves from the open position to a closed position and back by rotation in the same sense. In an alternative embodiment, two such valves members are provided and each valve member is actuable from a common control line to at least three operating positions, to. incrementally adjust flow through the ports. Methods of operation are also described.
摘要(中):
描述了井管阀,其具有连接在管状管柱中的基本上管状的主体和具有至少一个孔的旋转阀构件。 可以是具有部分球形表面的套筒的阀构件可相对于主体旋转移动,以使阀构件中的孔与主体中的端口对准和不对准。 阀构件可以在单个方向上相对于主体旋转,并且以相同的意义通过旋转从打开位置移动到关闭位置和后退。 在替代实施例中,提供了两个这样的阀构件,并且每个阀构件可从公共控制线致动至至少三个操作位置。 通过端口逐渐调整流量。 还描述了操作方法。
