摘要： Drilling systems and methods for deploying a latch mechanism upon reaching a drilling position. The drilling systems and methods permit spinning of a drill string to cause a core barrel head assembly to spin through the frictional mating of a landing shoulder of the head assembly and a landing ring of an outer tube assembly. The spinning of the drill string induces a centrifugal and/or radial force that acts on the latch mechanism to overcome the frictional retention forces acting on the latch mechanism, thereby permitting deployment of the latch mechanism.

摘要： A down-the-hole assembly includes a housing having a central axis and a mechanical gear box positioned within the housing. The mechanical gear box is coupled to the housing such that rotation of the housing at a first rotational rate provides a rotary input to the mechanical gear box. A rotary cutting bit is coupled to the mechanical gear box. The mechanical gear box is configured to rotate said rotary cutting bit at a second rotational rate in response to that rotary input from the housing. The second rotational rate is greater than the first rotational rate. The mechanical gear box is also further configured to cause the rotary cutting bit to orbit about the central axis of the housing.

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： 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.
