摘要： A cut and pull spear is configured to obtain multiple grips in a tubular to be cut under tension. The slips are set mechanically with the aid of drag blocks to hold a portion of the assembly while a mandrel is manipulated. An annular seal is set in conjunction with the slips to provide well control during the cut. An internal bypass around the seal can be in the open position to allow circulation during the cut. The bypass can be closed to control a well kick with mechanical manipulation as the seal remains set. If the tubular will not release after an initial cut, the spear can be triggered to release and be reset at another location. The mandrel is open to circulation while the slips and seal are set and the cut is being made. Cuttings are filtered before entering the bypass to keep the cuttings out of the blowout preventers.
摘要翻译：剪切和拉动矛被配置为获得在张力下被切割的管中的多个夹具。在操作心轴的同时，滑块借助于阻力块机械地设置以保持组件的一部分。一个环形密封件与卡瓦一起设置，以便在切割过程中提供良好的控制。密封件周围的内部旁路可以处于打开位置以允许切割期间的循环。在密封保持设置的情况下，可以关闭旁路以通过机械操纵来控制井涌。如果在初次切割后管状物不会释放，则可以触发矛释放并在另一个位置复位。心轴是开放的流通，而滑动和密封设置和切割正在进行。在进入旁路之前，钻屑被过滤，以防止钻屑从井喷器中流出。
