摘要： The present invention provides an apparatus and method for severing casing as it is pulled from a wellbore. An apparatus (100) is provided, comprising a clamping assembly (130), a drilling assembly (150) and a cutting assembly (120). In one aspect, the apparatus is disposed at the end of a telescopic arm (110), with the components being remotely operated by personnel using a control panel (125). The apparatus can be positioned adjacent casing (200') and clamped thereto. Thereafter, the apparatus can drill a hole completely through the casing for the insertion of a retention pin. The apparatus can then severe the casing into manageable lengths to facilitate disposal, such as during a plugging and abandonment procedure.

摘要： A method and related system for operating a downhole tool connected to coiled tubing (16) comprises introducing the tool (20) and the coiled tubing (16) into a wellbore (10), measuring by means of a load cell (24) compression, tension and/or impact forces applied to the tool (20) providing to the earth's surface a signal indicative thereof, using the signal to determine at the earth's surface the location of the tool (20) within the wellbore (10), and then operating the tool (20). This enables the operator to determine the tool's location so that the tool can be operated as required or retrieved. Possible applications are setting of a gas lift valve by means of a kickover tool, operating a shifting tool for moving the sleeve of a sliding sleeve valve, setting and retrieving of a flow control device such as a safety valve, blanking plug or standing valve.
摘要翻译：用于操作连接到连续油管（16）的井下工具的方法和相关系统包括将工具（20）和连续油管（16）引入井眼（10）中，借助于称重传感器（24）压缩测量，施加到工具（20）的张力和/或冲击力使用该信号向地球表面提供指示其的信号，以在地球表面确定工具（20）在井眼（10）内的位置，然后操作工具（20）。这使得操作者能够确定工具的位置，以便可以根据需要或检索操作工具。可能的应用是借助于翻转工具设置气举阀，操作用于移动滑动套筒阀的套筒的移动工具，设置和取回流量控制装置，例如安全阀，冲裁塞或立式阀。

摘要： A subsurface safety valve (10) of minimized length comprises a tubular valve housing (12) with a valve closure member (18) therein movable between an open and a closed position, an axially shiftable flow tube (24) for opening the valve closure member (18), a plurality of longitudinally disposed springs (38) radially spaced about the housing (12) for biasing the flow tube (24) to a closed position, and a piston and cylinder assembly (26) to move the flow tube (24) to an open position, with a portion of the assembly (26) longitudinally overlapping at least one of the springs (38). The safety valve includes simple mechanisms to lock out the safety valve, and to establish secondary hydraulic communication with a wireline set secondary valve set within the locked out safety valve.
