摘要:
According to one embodiment, a rotationally activated downhole well valve for connection in a tubing string is disclosed that can be repeatedly opened and closed selectively to place the tubing string in communication with the annulus. The valve is moved between the closed position and the open position by rotating the string in the first direction. In another embodiment, the valve is opened and closed by rotating the string in the first direction and is reset in the closed position by lifting and lowering the tubing string.
摘要(中):
根据一个实施例,公开了一种用于在管柱中连接的旋转致动井下阀门,其可以选择性地反复打开和关闭以将管柱与环空连通。 通过在第一方向上旋转弦,阀门在关闭位置和打开位置之间移动。 在另一个实施例中,通过在第一方向上旋转绳来打开和关闭阀,并且通过升高和降低管柱而在关闭位置重置阀。 p>
