摘要： A downhole tool that includes a cutter and jacking system and methods of using such a tool to remove a portion of casing or tubing from a wellbore. The tool may include an upper slip and a lower slip configured to selectively engage casing of a wellbore. A cutter and an extendable section may be positioned between the upper and lower slips. The cutter may be used to cut casing into an upper portion and a lower portion and the extendable section may be used to increase a distance between the upper and lower slips that moves the upper portion of the casing and the lower portion of the casing away from each other. The extendable section may be hydraulically actuated to move the upper portion of the casing away from the lower portion of the casing. The cutter may be an abrasive jet configured to cut the casing.

摘要： A cable head with cable shear mechanism, and method for installing the same. The cable head for attaching to a wireline to support oilfield equipment in a wellbore formed from a housing with a cable bore. The housing includes a tapered sleeve with a tapered sleeve cable bore, a sliding bell with a sliding bell cable bore, a drive pinch cylinder, a linear biasing mechanism positioned between the tapered sleeve and the drive pinch cylinder, a plurality of shear pins disposed partially into the housing and though the drive pinch cylinder, wherein each shear pin is adapted to withstand from 100 pounds to 2000 pounds of shear load, a pair of slidable cutting segments and a pair of slidable cutting segment guides. When cable load exceeds a preset limit, the shear pins shear allowing the slidable cutting segments to be moved up the slidable cutting segment guides to impact and shear the cable.

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： A pipe string in an oil well has a cable (2) slidingly attached along it. It may be necessary to break the pipe string. Apparatus is provided for controlling the position of a fracture in the cable, as it is desirable to break the cable at about the same point. The apparatus comprises a pocket (1) attached to the cable and having a passage through which the cable passes, and upper and lower nipples (5 and 6) attached to the cable in the pocket. The lower face (5') of the nipple (5) is skewed relative to the lower internal face (3') of the pocket and the facing faces (5", 6') of the two nipples are skewed relative to each other, so bending and kinking the cable when tension is applied. The cable therefore breaks at the bend or kink. The pipe string includes a plurality of such apparatuses located at spaced points along its length.

摘要： A tool for removing of one or more outer layers of a multi-layered jacketed wire includes a base member and a top member pivotally connected to the base member. The scoring tool has a first receiver recess on a first end of the scoring tool. A first cutter extends into a first receiver recess at a distance (d1) from an interior wall of the first receiver recess, and the first cutter is transversely oriented within the first receiver recess. A second cutter extends into a second receiver recess at a distance (di) from an interior wall of the second receiver recess, and the second cutter is longitudinally oriented within the second receiver recess.
