摘要： A remote controlled safety valve adapted for use in a well to shut-in production flow at a subsurface location. The valve operates by rotating a ball-type closure element after spacing the element from a pair of valve seats and then resealing the seats with the element after rotation is complete.

摘要： A well apparatus and method for communicating a plurality of flow conductor passages extending through a housing to enable controlled circulation between passages when desired while blocking flow through portions of the passages to assure a desired circulating flow path for performing various well operations. Increasing fluid pressure in either or both flow conductor passages establishes communication therebetween by operating a valve means while blocking flow in the other passage to obtain a desired flow circulation path. In the preferred embodiment the valve means for blocking the other flow conductor is located below the valve means to enable replacement of a standing valve by the use of fluid pressure movable tool trains without subjecting the producing formation to the fluid pressure circulating the tool train.

摘要翻译： 用于连通延伸穿过壳体的多个流动导体通道的井装置和方法，以便当需要时允许通道之间的受控循环，同时阻止流过通道的一部分，以确保用于执行各种井操作的期望的循环流动路径。 在任何一个或两个流动导体通道中增加流体压力通过操作阀装置同时阻止另​​一通道中的流动来建立连通，以获得期望的流动循环路径。 在优选实施例中，用于阻挡另一个流动导体的阀装置位于阀装置的下方，以使得通过使用流体压力可移动工具列可以更换立式阀，而不会使生成层对循环工具列的流体压力产生影响。

摘要： A subsurface well apparatus for connection in a production tubing having a housing with a controlled ball type bore closure means therein for normally controlling flow of fluid through the bore of the tubing and adapted to receive, secure and operate a replaceable means for controlling flow in the bore of the housing when the closure means malfunctions. The means for controlling flow in the bore is installed and retrieved from the housing through the bore of the tubing by a method utilizing pressure in the bore of the tubing.

摘要： A mud saver valve adapted to be disposed below a kelly for controlling the discharge of mud through the kelly into the drill string and for preventing loss of mud at the derrick floor from the kelly when it is disconnected with the mud saver valve from the drill string, wherein means are provided for preventing a closure of the mud saver valve, even though the mud supply pressure to the kelly is cut off, if there is well pressure in the drill string which might blow out upon a disconnection of the kelly, whereby the danger of having a well blowout upon a disconnection of the kelly may be avoided.

摘要翻译： 一种适用于设置在凯利下面的防泥塞阀，用于控制通过钻井进入钻柱的泥浆的排放，并且防止井架底部从井底脱落时与钻井柱与止泥阀断开连接 其特征在于，即使在井筒断裂时钻柱中存在良好的压力，即使向凯利施加的泥浆供应压力被切断，也提供了防止堵塞阀的装置，由此， 可以避免在断开凯利时有良好的井喷的危险。
