    • A milling system has been invented for milling an opening in a tubular in a tubular string in a wellbore extending down from a surface of the earth, the milling system, in one aspect, has a whipstock connected to an anchor assembly and a mill apparatus releasably connected to the whipstock, the mill apparatus having auto fill apparatus therein. A mill has been invented with a mill body with a top end and a bottom end, a flow bore through the mill body, and an auto fill apparatus in the flow bore. A valve assembly has been invented for selectively controlling fluid flow through a hollow tubular in a string of hollow tubulars in a wellbore extending from a surface of the earth into the earth, the valve assembly in one aspect having positions limited to at rest, circulate, and anchor set positions so that a fluid pressure indicating at the surface indicates only either a pressured up position for anchor setting or a pressured up position for fluid circulation. A milling system has been invented with apparatus for releasably containing an isolated charge of fluid. A float valve for use in wellbore operations has been invented with a valve member having a vent hole for releasing fluid pressure build up beneath the valve member. A fill sub has been invented which uses such a float valve.

    • A downhole wellbore tool has been developed which has a lower movable valve apparatus which, when it contacts a member in a wellbore or in a tubular in a wellbore, is moved to close off fluid flow through the item to which the valve apparatus is attached. In one aspect, such a valve apparatus is used below a mill above which is positioned a downhole motor which rotates the mill for milling. Actuation of the valve apparatus results in a cessation of the circulation of the motive fluid flowing to and through the motor so that milling stops. In one aspect the valve is selectively operable so that milling may be resumed. In another aspect such a tool is useful for indicating a known location in a wellbore when a decrease or cessation in fluid flow or a decrease in pressure is noticed at the surface.
    • 已经开发了一种井下井眼工具,其具有下部可动阀装置,当其与井筒中的构件接触或在井筒中的管状物中接触时,移动以关闭通过与阀装置连接的物品的流体流动。 在一个方面,这种阀装置在磨机下面使用,在其上方定位有使铣床旋转的井下马达。 阀装置的致动导致流过和通过电动机的运动流体的循环停止,从而停止铣削。 在一个方面,阀可选择性地可操作,使得可以恢复铣削。 在另一方面,当在表面上注意到流体流动减少或停止或压力降低时,这种工具可用于指示井筒中的已知位置。
