摘要： A tool for penetrating a tubular as described. The tool comprises at least one length of linear shaped charge, a carrier adapted to support the/each length of linear shaped charge, and at least one detonation mechanism for detonating the/each length of linear shaped charge. Upon detonation of the/each length of linear shaped charge, a length of material is projected outwardly from the/each length of linear shaped charge towards an internal surface of the tubular, which is thereby penetrated. The at least one length of linear shaped charge is arranged such that, upon detonation, the trajectory of at least one portion of the projected material intersects the trajectory of at least one other portion of projected material at or adjacent the internal surface of the tubular.
摘要翻译：用于穿透管道的工具10包括至少一个长度的线性成形装药18，适于支撑线性成形装药的每个长度的载体以及用于引爆线性成形装药18的每个长度的至少一个爆轰机构。在引爆线性成形装药18的每个长度时，一定长度的材料从线性成形装药18的每个长度朝向管状物的内表面向外突出，管状物的内表面由此穿透。至少一个长度的线性成形装药18被布置成使得在爆炸时，投射材料的至少一部分的轨迹与位于或邻近管的内表面的投影材料的至少一个其他部分的轨迹相交。结果是穿透物在管的表面上限定封闭区域或形状38。工具10也可以用于穿透其他物体。

摘要： A tool for manipulating a tubular, such as casing or production tubing, in a downhole environment, this described. The tool comprises a housing defining a chamber, the chamber having at least one outlet, a propellant source located within the chamber and an ignition mechanism for igniting the propellant source. Upon ignition of the propellant source, the propellant deflagrates, creating at least one stream of combustion products, the chamber directing the stream of combustion products through the/each outlet, towards the tubular to be manipulated, the/each stream of combustion products combining with at least one modifying agent to manipulate the tubular.
摘要翻译：用于在井下环境中操纵诸如套管或生产管道的管12的工具10包括限定室22的壳体20，室22具有至少一个出口24，位于室22内的推进剂源26和用于点燃推进剂源26的点火机构。当点燃推进剂源26时，推进剂爆燃，产生至少一个燃烧产物流44，室22引导燃烧产物流通过/每个出口24，朝向管12将被操纵，每个燃烧产物流与至少一种改性剂28结合以操纵管。可以存在多种推进剂，并且偏转器39可以改变燃烧产物44的路径。改性剂28可以是氧化铝。
