摘要： High productivity core drilling systems include a drill string, an inner core barrel assembly, an outer core barrel assembly, and a retrieval tool that connects the inner core barrel assembly to a wireline cable and hoist. The drill string comprises multiple variable geometry drill rods. The inner core barrel assembly comprises a non-dragging latching mechanism, such as a fluid-driven latching mechanism that contains a detect mechanism that retains the latches in either an engaged or a retracted position. The inner core barrel assembly also comprised high efficiency fluid porting.

摘要： Implementations 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. 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： Fibers for diamond-impregnated cutting tools and their associated methods for manufacture and use are described. A matrix is formed that contains fibers made from carbon, glass, ceramic, polymer, and the like. The matrix is then sintered to form a cutting portion of a drill bit. The type and concentration of the fibers can be modified to control the tensile strength and the erosion rate of the matrix to optimize the cutting performance of the tools. Additionally, the fibers may be added to the cutting section to weaken the structure and allow higher modulus binders to be used for the cutting tools at a lower cost, allowing the amount of fibers to be tailored to retain the diamonds in the cutting portion for the desired amount. As the cutting portion erodes, the fibers may also increase the lubricity at the face of the cutting portion.
