摘要： A system for installing and removing a production packer and ball valve apparatus in a well casing. The packer apparatus and valve apparatus are transported into a casing with an on/off overshot connected to a string of tubing. The packer is set by tubing manipulation independent of operation of the valve and the on/off connector and is resettable and can be disabled by a straight upward pull on the tubing string. The valve apparatus is selectively operable by rotary manipulation of the tubing string through the disengageable overshot and utilizes rotary motion to rotate a ball valve element between open and closed positions of the ball valve. In one form of the invention, the overshot is rotatably disengageable from the ball valve while the ball valve is operated by rotation of the string of pipe. The ball valve apparatus is capable of withstanding pressure in opposite directions.
摘要翻译： 一种用于在井套管中安装和移除生产封隔器和球阀装置的系统。 封隔器装置和阀装置被输送到具有连接到一串管道上的开启/关闭过冲的壳体中。 封隔器通过管道操作设置，独立于阀和开/关连接器的操作，并且可重置，并且可以通过油管柱上的直的向上拉动来禁用。 阀装置可选择性地通过可分离的过冲的油管柱的旋转操作来操作，并利用旋转运动使球阀元件在球阀的打开和关闭位置之间旋转。 在本发明的一种形式中，当球管通过管束旋转而操作时，过冲可旋转地脱离球阀。 球阀装置能够承受相反方向的压力。

摘要： A packer is disclosed having a setting piston mounted on the body thereof. The packer is hydraulically set prior to treating or cementing. The packer has a sliding sleeve valve which is open during run-in. After the packer has set, the setting tool is released from the valve. The valve may then be operated through manipulation of the tubing string. The tubing string can be disengaged and reengaged into the packer body to determine if the valve has closed by measuring the pressure conditions at the surface.
