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： Drill rods having an outer surface that is at least partially non-carburized and at least partially coated with a corrosion-resistant material. The corrosion-resistant material can be chemically bonded to the outer surface of the elongate body. Optionally, the outer surface of the drill rods can define a threaded portion having a plurality of threads and a plurality of roots positioned between adjacent threads. Each thread can have a crest spaced radially outwardly from adjacent roots. Each crest can have a respective hardness, and each root can have a respective hardness. The hardness of the crest of each thread can be greater than the hardness of the roots adjacent to the thread. Systems and methods for making and using the disclosed drill rods are also described.

摘要： Aspects of the present invention include drill string components having a thread extending around a body. The leading end of the thread can have a configuration that resists jamming and cross-threading. In particular, the leading end of the thread can include a planar surface normal to the body. The leading end of the thread can provide an abrupt transition to full thread depth that helps reduce or eliminate cross-threading. The leading end of the thread can be oriented at an angle relative to the axis of the drill string component. When mating male and female threads are similarly structured, the mating threads slide together along an interface at the thread start face and are drawn into a fully thread-coupled condition. The thread starts may have full circumference mating with no jamming positions.
