摘要： A cutting assembly for external conduits on a tubing string or main tubular conduit features at least one breakaway in the string that can be severed with a tensile force. Preferably each external conduit is run through a cutter housing that is integral with a passage having threaded end connections. While in some scenarios it is preferred that the main tubular conduit is severed below the cutting assembly thus allowing the cutting apparatus to be retrieved with the upper portions of the cut main tubular conduit and external longitudinal member(s), in other circumstances it may be desired that the main tubular conduit is severed above the cutting assembly allowing the cutting apparatus to be left "downhole" with the lower portion of the cut main tubular conduit and the BHA. The cutter knife assembly chambers or channels can be in banks that are axially spaced using bypass channels to access lower banks. The cutter knife assembly and associated channels can be mirror images so that the external conduits can be cut regardless of where the tubing string is severed and one or more conduits can be cut with a single cutter assembly.
摘要翻译：用于管柱或主管道上的外部管道的切割组件具有至少一个可以用张力切断的绳子中的分离。优选地，每个外部导管穿过与具有螺纹端部连接的通道成一体的切割器壳体。虽然在一些情况下，优选的是主管状导管在切割组件下方被切断，从而允许切割装置与切割的主管状导管和外部纵向构件的上部分一起取回，在其他情况下它可以是期望主管状导管在切割组件上方被切断，从而允许切割装置与切割的主管状导管的下部和BHA一起“离开”井下。切刀组件腔室或通道可以在使用旁路通道轴向隔开的库中以进入下部库。切割刀组件和相关的通道可以是镜像的，从而无论管柱被切断的位置和一个或多个管道可以用单个切割器组件切割，可以切割外部管道。

摘要翻译：用于管柱或主管状导管上的外部导管的切割组件具有可以用拉力切断的弦中的至少一个分离。优选地，每个外部管道穿过与具有螺纹端部连接的通道成一体的切割器壳体。虽然在某些情况下，优选的是，主管状导管在切割组件下方被切断，从而允许切割装置与切割的主管状导管和外部纵向构件的上部一起被取回，在其他情况下可以是期望主管状导管在切割组件上方被切断，允许切割装置与切割的主管状导管和BHA的下部分“下井”。切割刀组合室或通道可以是使用旁路通道轴向隔开以接近下层的堤。切割刀组件和相关通道可以是镜像，使得可以切割外部管道，而不管油管柱被切断的位置，并且可以用单个切割器组件切割一个或多个管道。
