摘要： An assembly may be disposed within a drill string. The assembly may be moved within and along the drill string using hydraulic pressure. A core sample may be collected within the assembly, and the assembly may be retrieved to obtain the core sample. The assembly may include a seal that may be configured to form a seal with different inner diameters of a variable-diameter drill rod of the drill string.
摘要翻译：组件可以布置在钻柱内。该组件可以使用液压在钻柱内和钻柱上移动。可以在组件内收集岩心样品，并且可以取回组件以获得岩心样品。该组件可以包括密封件，该密封件可以构造成与钻柱的可变直径钻杆的不同内径形成密封。

摘要： Implementations of the present invention include a core barrel assembly having a driven latch mechanism. The driven latch mechanism can lock the core barrel assembly axially and rotationally relative to a drill string. The driven latch mechanism can include a plurality of wedge members positioned on a plurality of driving surfaces. Rotation of the drill string can cause the plurality of wedge members to wedge between an inner diameter of the drill string and the plurality of driving surfaces, thereby rotationally locking the core barrel assembly relative to the drill string. The driven latch mechanism can further include a retracted groove adapted to lock the plurality of wedge members radially within the core barrel assembly, thereby allowing for faster travel within the drill string. Implementations of the present invention also include drilling systems including such driven latch mechanisms, and methods of retrieving a core sample using such drilling systems.
摘要翻译：本发明的实施方式包括具有从动闩锁机构的芯筒组件。从动闩锁机构可以相对于钻柱轴向且旋转地锁定岩心筒组件。从动闩锁机构可以包括定位在多个驱动表面上的多个楔形构件。钻柱的旋转可导致多个楔形件在钻柱的内径与多个驱动表面之间楔入，从而将岩心管组件相对于钻柱旋转锁定。从动闩锁机构可进一步包括适于将多个楔形构件径向锁定在岩芯筒组件内的缩回凹槽，由此允许在钻柱内更快地行进。本发明的实施方式还包括包括这种从动闩锁机构的钻井系统，以及使用这种钻井系统回收岩心样品的方法。
