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：本发明的实施方案包括具有从动闩锁机构的芯筒组件。从动锁定机构可以相对于钻柱轴向和旋转地锁定芯筒组件。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。钻柱的旋转可以导致多个楔形构件在钻柱的内径和多个驱动表面之间楔入，从而相对于钻柱旋转地锁定岩心筒组件。从动闩锁机构还可以包括适于将多个楔形构件径向地锁定在芯筒组件内的缩回凹槽，从而允许在钻柱内更快的行进。本发明的实施方式还包括包括这种被驱动的锁定机构的钻井系统，以及使用这种钻井系统取回岩心样品的方法。

摘要： Implementations of the present invention include a core barrel assembly including external fluid pathways extending generally axially long the outer surface of the core barrel assembly. The one or more external fluid pathways can allow for increased fluid flow around a latch mechanism. The increased fluid flow around the latch mechanism can allow the core barrel assembly to travel faster within the drill string, can allow drilling fluid to pass by the latch mechanism when engaged. Implementations of the present invention also include drilling systems including external fluid pathways, and methods of retrieving a core sample using such drilling systems.

摘要： A drill bit for cutting a hole in a formation. The drill bit has a shank and a crown. The crown has a plurality of crown portions that are spaced about an operative circumference of the drill bit. The shank and crown cooperate to define an interior space that receives water or other drilling fluid. Each crown portion has two longitudinal edges, an outer surface, at least one inner surface and a cutting face. The crown has a base surface that is spaced from the cutting faces of the crown portions and cooperates with the inner surface of each of the two crown portions to define a slot.
