    Abstract: A latch assembly, and methods of using the latch assembly, for use with a bottom hole assembly (BHA) and a tubular, are provided. In one embodiment, the latch assembly is disposable within the tubular, configured to be rotationally and axially coupled to the tubular. In one aspect of the embodiment, latch assembly is configured to be released from the tubular by applying a tensile force to the latch assembly. The latch the latch assembly may comprise: one or more sleds disposed within one or more respective slots formed along at least a portion of a locking mandrel; and one or more retractable axial drag blocks configured to engage a matching axial profile disposed in the tubular, wherein each axial drag block is coupled to the respective sled with one or more biasing members; and the locking mandrel actuatable between a first position and a second position and preventing retraction of the axial drag blocks when actuated to the second position. The latch assembly may also comprise a drag block body having a bore therethorugh; and one or more retractable torsional drag blocks configured to engage a matching torsional profile disposed in the tubular, wherein each torsional drag block is coupled to the drag block body with a biasing member.

    Abstract translation: 提供了一种闩锁组件，以及使用闩锁组件与底部孔组件（BHA）和管状件一起使用的方法。 在一个实施例中，闩锁组件在管状件内是一次性的，构造成可旋转地和轴向地联接到管状体。 在该实施例的一个方面中，闩锁组件构造成通过向闩锁组件施加张力而从管状件释放。 闩锁组件的闩锁可以包括：设置在沿着锁定心轴的至少一部分形成的一个或多个相应狭槽内的一个或多个滑板; 以及一个或多个可缩回的轴向阻力块，其构造成接合设置在管状物中的匹配轴向轮廓，其中每个轴向阻力块通过一个或多个偏置构件联接到相应的滑架; 并且所述锁定心轴可在第一位置和第二位置之间致动，并且防止当致动到所述第二位置时所述轴向阻力块的缩回。 闩锁组件还可以包括具有孔的拖块主体; 以及一个或多个可缩回的扭转阻力块，其构造成接合设置在所述管状体中的匹配的扭转轮廓，其中每个扭转阻力块利用偏置构件联接到所述阻力块体。
