摘要： A latching connection mechanism (4, fig. 5) comprises first and second components (6 & 8, fig. 5) which can be selectively coupled together, one of the components comprises a locking member 25 which can be in the form of an elongate pin having mounted or integrally-formed spheres 27. The locking member is moveable between a first state and a second state and can have a spring 30. The other of the first or second component comprises means such as a cam surface for initially moving the locking member from the first to the second state as the first and second components are initially drawn together and a feature such as a groove 19 for returning the locking member to the first state once the first and second components are fully engaged together to prevent disengagement of the first and second components. The latching connection mechanism can be used in a wellbore transport assembly.

摘要： A sensor transportation apparatus to convey a sensor assembly through a wellbore. The apparatus comprising has an engagement structure to connect the sensor transportation apparatus to the sensor assembly, and one or more wheels arranged to rotate about an axis of rotation substantially perpendicular to a longitudinal axis of the sensor assembly when the transportation apparatus is connected to the sensor assembly. An orientation structure defining a form having a transverse outline which has a rotational center, wherein the rotational center is offset from a centroidal axis of the elongate sensor assembly.

摘要： A telebending tool for conveying a logging tool into a wellbore includes a tool body configured to couple to a logging tool, wherein the body has a central axis. The telebending tool also includes a cam housing coupled to the tool body and having a cam pathway and a nose moveably coupled to the tool body through a pivoting member, wherein the nose has a central axis. The telebending tool further includes a compression spring positioned between the nose and the pivoting member and a camming arm coupled to the nose. The camming arm extends coaxially through the pivoting member to selectively engage the cam pathway of the cam housing. The nose has a first position with the central axis of the nose coaxially aligned with the central axis of the body and a second position with the central axis of the nose oriented at an angle less than 180 relative to the central axis of the body. The nose is configured to be transitioned from the first position and the second position by application of an axial force to the nose.

摘要： A drill string member comprising a body (1), and bearing races (5) around the circumference of the member. In certain embodiment, the presence of spherical bearings (25) on the surface of the member reduces radial torque and vertical drag to enable easier operation of the drill string. Advantages of one embodiment includes a reduction in the wear or breakages of the components used in drilling.

摘要： In a method for use in dry, rotary, crushing full-area drilling, use is made of suction air alone for removing cuttings produced during drillings. To carry out the method, two suction nozzles (13) are arranged on the underside of a cutterhead (1). These nozzles together have a substantially diametrical extent and the length of a radius on the cutterhead and are provided with suction intakes (14A) in the vicinity of the periphery of the cutterhead. The suction intakes (14A) are connectible a common suction channel (11) in the drill string (6) of the cutterhead. The suction channel (11) has substantially constant diameter.
