    • An apparatus (10) for handling tubulars with respect to a borehole (13) includes a mandrel (12) having a plurality of angled faces (16) and an external sliding sleeve (20) carried on the mandrel. The sliding sleeve has connected for sliding movement therewith a plurality of grapples (22). The grapples are positioned to overlie the mandrel faces. At least one of the mandrel faces or the inner surfaces of the grapples are angled such that rotation of the mandrel relative to the grapples causes the grapples to be driven radially outwardly from the mandrel. In use, the apparatus is inserted into a tubular and the grapples are driven outwardly by relative rotation of the grapples and the mandrel to cause the grapples to engage against the inner surface of the tubular in which the apparatus is positioned.
    • 用于处理相对于钻孔(13)的管状物的设备(10)包括具有承载在心轴上的多个成角度面(16)和外部滑动套筒(20)的心轴(12)。 滑动套筒连接有滑动运动与多个抓斗(22)。 抓斗定位成覆盖在芯棒表面上。 所述抓斗的至少一个心轴表面或内表面是成角度的,使得所述心轴相对于所述抓钩的旋转导致所述抓斗从所述心轴径向向外驱动。 在使用中,将装置插入管状件中,通过抓斗和心轴的相对转动将抓斗向外驱动,以使抓钩与装置所在的管状物的内表面接合。

    • A downhole steering tool comprises a hollow mandrel (11), an independently rotatable sleeve (12) extending over a portion of the mandrel (11), steering plungers (26) carried by the sleeve (12) and extendable and retractable laterally to and from pressure contact with the hole wall (28) for steering a drill below the tool when in use, releasable locking means (14) for locking the sleeve (12) to the mandrel (11) rotationally, and fluid control means (15) operable to direct to the locking means (14) and the steering plungers (26) a portion from fluid circulation through the mandrel (11) to release the locking means (14) and to extend the steering plungers (26) by means of pressure of the fluid.
    • 井下转向工具包括中空心轴(11),在心轴(11)的一部分上延伸的可独立旋转的套筒(12),由套筒(12)承载的转向柱塞(26),并且可向侧向伸缩 (28)的压力接触,用于在使用时将工具引导到工具下方;可释放的锁定装置(14),用于旋转地将套筒(12)锁定到心轴(11);以及流体控制装置(15) (14)和转向柱塞(26)引导通过心轴(11)的流体循环的一部分以释放锁定装置(14)并通过流体的压力使转向柱塞(26)伸出 。
