摘要： A bow-spring centralizer (6) includes bow springs (5), moving collars (11) secured to each end of each bow spring, and interlocked stop collars (10). Extendable collars (8) may each be formed of a moving collar (11) movably interlocked with a stop collar (10). The centralizer (6) may optionally be formed from a tube cut using a laser to create two extendable collars coupled by bow springs. Each extendable collar may include heads integrally formed on extensions protruding from a collar (stop collar or moving collar). The heads may be generally rectangular, arrow, or teardrop-shaped head or some other shape. Each head may be slidably captured within a chamber on the interlocked collar (moving collar or stop collar). The extensions of each interlocked tubular member define the outer walls of the chamber in which a head of the interlocked tubular member is slidably captured. The stop collars may include or cooperate with one or more fingers extending along a casing to be secured by a sleeve that forms an interference fit about the casing.

摘要： In one embodiment, a wear band comprises a rotating element having a bore receivable on a tubular, the bore comprising first and second bore portions slidably receiving first and second sleeve bearings. Outer surfaces of the sleeve bearings slidably engage the bore portions and the bores of the sleeve bearings slidably engage the tubular. A first and a second stop collars may be received on the tubular to together straddle the rotating element and sleeve bearings to longitudinally secure the rotating element in a position on the tubular. The tubular may be included within a tubular string run into a borehole or into the bore of an installed casing, such as in casing while drilling. The rotating element provides stand-off between a tubular and the wall of a bore, reduces frictional resistance to longitudinal sliding and also to rotation of the tubular string within the bore.

摘要： A stop collar is assembled using a method including the steps of receiving a bore of a base having a set of fingers extending along an exterior of a tubular, receiving a bore of a sleeve onto the tubular adjacent the set of fingers, and receiving the sleeve onto the set of fingers in an interference-fit. In alternate embodiments, the base comprises a plurality of angularly distributed fingers and/or the base comprises a gap to permit conformance of the base to the tubular. A fingerless base may cooperate with one or more separate fingers to form a base. In an embodiment of the method, the sleeve may be thermally expanded prior to the step of receiving the sleeve onto the set of fingers. The sleeve may be heated to expand the bore prior to being received onto the set of fingers.

摘要： An actuator to actuate a device received on a tubular string adjacent the device. The actuator comprises an energy storage member, such as a spring, restrained in a compressed mode between a stop collar and an outer sleeve threadedly received on a threaded portion of a non-magnetic tubular segment. An outer magnet is coupled to the outer sleeve to magnetically interact with an inner magnet coupled to an inner pipe string. The inner pipe string is run into the bore of the tubular string and the outer sleeve to position the inner magnet proximal the outer magnet to form a magnetic clutch. The inner pipe string rotates to transfer torque to the outer sleeve via a magnetic clutch, to rotate and threadedly disengage the outer sleeve from the tubular segment to release energy from the energy storage member to displace the outer sleeve to engage and actuate the device.
