摘要： A method (60) of determining core orientation of a core sample (12) cut from the ground by a drill rig (10) having a drill string and a drill bit (20) coupled to a downhole end of the drill string. Drilling data (Cn, Rn) is continuously acquired while the drill rig (10) is operating to cut and retrieve the core sample (12). The drilling data is a combination of core orientation data Cn and rig operational data Rn, where the rig operational data is constituted by either one or both of: (a) near bit rig data Nn; and, (b) at surface rig data Sn. The drilling data is analysed for a specific pattern of rig operational data Rn indicative of the core sample being broken from ground by operation of the drill rig (10). On detection of the specific pattern, the orientation of the core sample prior to being broken from the ground is the acquired core orientation data Cn coinciding with that specific pattern of rig operational data Rn.

摘要： A rotation actuated core orientation system (10) for a ground drill comprises an orientator (14) and rotation sensitive actuator (16). The actuator (16) is a dispersed system comprising two major components or subsystems namely a centrifugal mechanism (16a) and a time delay mechanism 16b between which is located the bottom orientator (14). The orientator (14) has an active state where the orientator provides a substantially instantaneous indication of a position of a known bearing or reference location in or of the hole, and a locked state where the orientator maintains the indication. The rotation sensitive actuator (16) isoperatively associated with the orientator (14) to actuate the orientator (14) to enter the active state or the locked state dependant on rotational speed of the ground drill.

摘要： A retraction system is described for allowing disengagement of retrieval latch dogs (114) of a down hole running tool (14) from a bit locking sleeve (18). The locking sleeve (18) is slidably retained within a drive sub (12) and includes a pair of slots (66) which are engaged by the retrieval latch dogs (114) when the tool (14) is used to retrieve bit segments (16) from the drive sub (12). The retraction system includes a sleeve (76) which is slidably mounted on a main body (74) of the tool (14) and spring (174) which is biased to push the sleeve (76) over the retrieval latch dogs (114). The sleeve (76) has a pair of diametrically opposed slots (235) through which the retrieval latch dogs can extend for contacting the inner surface (28) of the drive sub (12). The retraction system also includes a length (44) of the inner surface of the drive sub (12) which is made of progressively reducing diameter in the direction of retraction of the tool (14) from the drive sub (12). The upper end of each slot (235) is provided with a bevel (236) for directing the retrieval latch dogs (114) in the inward direction. To withdraw the tool (14) from the drive sub (12), the retrieval latch dogs (114) are disengaged from the bit locking sleeve (18) by the combined action of the shape of surface portion (44) which acts to push the retrieval latch dogs (114) inwardly, together with the force of spring (174) and the bevelled surfaces (236) which act to push the sleeve (74) over the retrieval latch dogs (114) thereby disengaging it from the bit locking sleeve (18).

摘要： A spearhead assembly (10) comprises a base (12) provided with a slot (14) at one end (16) which opens onto an outer surface (13) of the base (12). The outer surface (13) is composed of three contiguous surface portions (18, 20 and 22). A spearpoint (20) is pivotally coupled at its proximal end (26), which is disposed in the slot (14), to the base (12). A distal end (28) of the spearpoint (24) extends or projects beyond the slot (14) and the surface (13) of the base (12). A spearpoint positioning system (30) urges the spearpoint (24) toward one of three annually spaced positioned. These positions are characterised by the spearpoint (24) extending substantially perpendicular to parallel opposed edges of the slot (14) which open onto, or are flanked by, the surface portions (18), (20 and 22). Moving the spearpoint from one position to another requires the application of an external force.

摘要： A method (100) of enabling at surface orientation data transfer from a contactless orientation system (11) coupled with an inner core tube (12) to one or more record carriers on or associated with a core sample (14) held in the core tube, the core sample (14) having a longitudinal core axis (16) and a core face 18 accessible from an end of the inner core tube (14), involves three broad steps. A first step is to couple an instrument guide (20) to the end of the core tube (12) from which the core face (18) is accessible so that an axis (26) of the guide is parallel to the core axis (16). A second step is to generate correlation information between a rotational orientation of a known point P on the instrument guide (20) or an instrument (28a) supported by the instrument guide (20) about the guide axis (26) and core orientation data known to the contactless orientation system (11). A third step is to use or otherwise operate the instrument (28a) to: act as the record carrier; or generate the record carrier provided with the correlation information enabling orientation of the core sample (14) to its in-situ orientation when released from the core tube (12).

摘要： An overshot (10) comprises a latching mechanism (12) for latching a member such as a spear point (14); and, an actuator (16) which actuates the latching mechanism (12). The latching mechanism (12) has a number of different operational states. One of these is a neutral state in which latching mechanism (12) is able to latch or capture a spear point (14). In the neutral state, latching mechanism (12) is able to open in order to receive spear point (14) and then self- close to latch or retain the spear point (14). Latching mechanism (12) also has a locked state in which it is locked in a closed position by actuator (16) to prevent the release of a latched spear point (14). The third state is the release state where the overshot is locked in an open position by actuator (16) to release a previously latched spear point (14). The actuator (16) operates as a linear to rotary motion converter which converts linear motion of one part of the actuator to a rotary motion of another part of the actuator between a plurality of rotationally spaced positions. The rotational positions determine the state of the latching mechanism.

摘要： A spear head assembly (10) comprises a main body portion (14) with axially opposite first and second ends (16 and 18) respectively. The first end (16) is adapted for threaded connection with a down hole tool (12). The tool which does not form part of the invention is provided with an internal fluid flow path (13). Passage (20) is formed in the main body portion (14) and extends between first and second spaced apart openings O1 and O2 which are coincident with the first end and the second end (16 and 18) respectively of the main body portion (14). Spear point (22) is coupled to the main body portion (14) at, and extends from, the second end (18). In use, when the spear head assembly (10) is coupled to tool (12), to facilitate connection of the tool to a wireline and overshot via the spear point (22), the passage (20) is in fluid communication with the path (13). Therefore, fluid such as drilling mud can glow through the path (13) in a substantially unimpeded manner.
