| A latch body for use in a drilling head assembly including a fluid control subassembly, a check valve element, and/or a hollow spindle. A distal end portion of the latch body includes a port section that defines a chamber for receiving the check valve element and promoting movement of the check valve element between a blocking position and an open position. The hollow spindle of the fluid control subassembly is operatively coupled to the chamber of the port section and supports the check valve element in the blocking position. A proximal end portion of the latch body supports the fluid control subassembly of the drilling head assembly in an operative position. The latch body includes male protrusions extending inwardly toward and spaced from a longitudinal axis of the latch body. A plurality of channels extend radially outwardly from the longitudinal axis of the latch body, spanning between adjacent male protrusions. | ||||||

| 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 refracted 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. | ||||||

| Disclosed is a core drill comprising: an external pipe; a coring bit to be rotated by rotation of the external pipe to drill a coring hole and form a core having a core diameter; and an internal coring pipe (1), mounted within the external pipe, to receive a core formed by the coring bit, the internal coring pipe comprising: an internal tubular wall (2) defining a cavity (4) having a diameter substantially the same as the core diameter within which to retain a core formed by the coring bit, one or more viewing openings (8, 9, 10) being formed through the internal tubular wall; and an external tubular wall (3), in which the internal tubular wall is housed coaxially, the internal and external tubular walls being connected to each other so as to form a single-piece double-walled pipe. | ||||||
| 185 | METHOD AND DEVICE FOR CORE DRILLING | EP09770462.1 | 2009-06-08 | EP2313604A1 | 2011-04-27 | BROSTRÖM, Johan |
| A method in core drilling, wherein a tubular drill bit (8) being arranged at the end of a tubular drill string (6) is driven under rotation against a material intended for drilling, and wherein for the purpose of core retrieving, a tool (17, 20) is brought inside the drill string to an operative position in the area of the drill bit. Acoustic vibrations (24, 25) from the drill string are sensed when the tool is brought to its operative position, sensed acoustic vibrations are analysed for detecting the occurrence of acoustic vibrations characteristic for when the tool has reached its operative position, and an output signal is emitted when the occurrence of vibrations characteristic of when the tool has reached its operative position has been detected. The invention also concerns a device and a drill rig. | ||||||
| 186 | HIGH PRODUCTIVITY CORE DRILLING SYSTEM | EP08731246.8 | 2008-03-03 | EP2132395A1 | 2009-12-16 | DRENTH, Chris |
| High productivity core drilling systems are described. The system includes 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 detent mechanism that retains the latches in either an engaged or a retracted position. The inner core barrel assembly also comprised high efficiency fluid porting. Accordingly, the drilling system significantly increases productivity and efficiency in core drilling operations by reducing the time required for the inner core barrel assembly to travel through the drill string. Other embodiments are also described. | ||||||

| Coring apparatus (10) and method are disclosed which provide for hydraulic latching of an inner core barrel (26) within an outer core barrel (12). The apparatus includes a valve face (48) disposed around the inner core barrel (26) and valve seat (52) disposed around the bore of the outer core barrel (12) that close to form a restriction in drilling fluid flow path (54). A hydraulic differential force is thereby created which holds the inner barrel (26) in place. Axially oriented bores (64) in a hanger assembly (58) and in stabilizers (62) are disposed along the inner core barrel (26) to provide a flow path for the drilling fluid after the restriction is formed. The bores are calibrated to produce a pre-determined hydraulic force on the inner barrel (26). A bearing assembly (30) is used to prevent transmission of outer barrel (12) rotation to the inner core barrel (26). The outer surface of the bearing assembly (30) forms the valve face (48) so as to form the drilling fluid restriction and also provides an axial stop that prevents further axial movement of the inner barrel (26) towards the core head (14). | ||||||

A device in core drilling for indicating when a core barrel placed in a rotatable hollow drill rod is no longer capable of receiving a further quantity of reamed-out core material includes a valve which at said condition of the barrel constricts the passage for flushing medium flowing between the core barrel and the bore of the drill rod so that a readable flushing medium pressure increase occurs. The valve closes off said passge incompletely to allow a minor quantity of flushing medium to be taken to the drill bit mounted at the bottom of the drill rod, thereby to prevent said drill bit from being burnt out. |
