摘要:
A piping is provided with an RFID tag for identifying the piping, wherein the piping comprises a first end section for being coupled to a second piping and a second end section for being coupled to a third piping. The piping further comprises a mid-section in between the end sections. The RFID tag is provided in an elongate recess that is formed in the piping and that extends in a tangential direction parallel to a surface of the mid-section of the piping.

Some embodiments of the present clamps include a first clamp portion having a first end defining a recess and a second end configured to be coupled to a first structure, a second clamp portion having a first end configured to be coupled to a second structure and a second end configured to be received in the recess of the first clamp portion, and a shear pin configured to secure the second clamp portion relative to the first clamp portion. Some embodiments include a retaining member disposed in the recess. In some embodiments, the recess and/or retaining member is configured to resist shearing of the shear pin if a force is applied to the second clamp portion in a first direction, but not if the force is applied in a second direction. In some embodiments, the first direction is substantially parallel with, but opposite to, the second direction.

Disclosed are embodiments of expandable bullnose assemblies for use in a well system. One well system includes: a deflector arranged within a main bore of a wellbore and defining a first channel that exhibits a predetermined diameter and communicates with a lower portion of the main bore, and a second channel that communicates with a lateral bore; a bullnose assembly including a body and a bullnose tip arranged at a distal end of the body, the bullnose tip being actuatable between a default configuration, where the bullnose tip exhibits a first diameter, and an actuated configuration, where the bullnose tip exhibits a second diameter different than the first diameter; a collet body forming at least part of the bullnose tip and defining a plurality of axially extending fingers; a radial protrusion defined on an inner surface of the collet body and extending radially inward from each axially extending finger; and a piston movably arranged within a piston chamber defined within the collet body and having a wedge member defined on an outer surface thereof, the piston being actuatable such that the wedge member engages the radial protrusion and forces the plurality of axially extending fingers radially outward, wherein, when the plurality of axially extending fingers is forced radially outward, the diameter of the bullnose tip exceeds the predetermined diameter, wherein the deflector is configured to direct the bullnose assembly into one of the lateral bore and the lower portion of the main bore based on a diameter of the bullnose tip as compared to the predetermined diameter.

A rotating control device can include an annular seal, and a latch including a rotary cam and an engagement member which releasably secures the seal and/or a bearing relative to the housing, such that rotation of the cam relative to the housing displaces the member. A method of latching an annular seal relative to an outer housing of a rotating control device can include rotating a rotary cam, thereby linearly displacing an engagement member that releasably secures the seal relative to the housing while permitting rotation of the seal relative to the housing. Another rotating control device can include an outer housing, an annular seal, and a latch including a rotary cam and multiple separate engagement members disposed in the housing, and in which rotation of the cam relative to the housing displaces the members in the housing.

Antriebswelle (6) für eine Werkzeugmaschine (1), beispielsweise eine Kernbohrmaschine, verbindbar mit einem Bohrwerkzeug (2), insbesondere einer Bohrkrone, enthaltend einen sich im Wesentlichen über die gesamte Länge der Antriebswelle (6) und entlang der Rotationsachse (M) erstreckenden Hohlraum (11), wobei der Hohlraum (11) wenigstens eine Zuflußöffnung enthält, durch die Wasser (W) entlang der Antriebswelle in das Bohrwerkzeug zuführbar ist, dadurch gekennzeichnet, dass eine Einsatzvorrichtung (14) in dem Hohlraum (11) vorgesehen ist, durch die das Wasser (W) zum Kühlen der Antriebswelle (6) zuerst in eine erste Richtung (A) und anschließend in eine zweite Richtung (B) geführt wird, wobei die Einsatzvorrichtung (14) ein erstes gebogenes Führungselement (13) sowie ein zweites gebogenes Führungselement (15) enthält zum Trennen des Wassers (W), welches in die erste Richtung (A) geführt wird, von dem Wasser (W), welches in die zweite Richtung (B) geführt wird, und wobei die Querschnittsfläche (Q1) des ersten gebogenen Führungselements (15) punktsymmetrisch um eine Mittelängsachse (M) zu der Querschnittsfläche (Q2) des zweiten gebogenen Führungselements (15) ausgestaltet ist.
摘要:
The subject matter of this specification can be embodied in, among other things, a method that includes providing an outer tubular member having a bore with an inner surface, applying a lubricant layer to at least a portion of the inner surface of the outer tubular member, positioning the outer tubular member in at least a portion of the wellbore, providing a drilling assembly including an inner member having an outer surface, applying a lubricant layer to at least a portion of the outer surface of the inner member, inserting the inner member into the bore of the outer tubular member, providing a drilling fluid through the bore of the drilling assembly, rotating the inner member relative to the outer member, measuring an indicator of mechanical wear between the outer member and the inner member, determining that the measured indicator exceeds a predetermined threshold level, and triggering a subsequent operation.
