摘要： A close-tolerance expandable bow spring centralizer 8 having a first expandable collar 10A coupled to and spaced apart from a second expandable collar 10B through a plurality of bow springs 30 wherein expandable collars 10A, 10B comprise a plurality of slidably coupled links 16 that separate to expand the diameter of the collars 10A, 10B, e.g., upon expansion of an expandable pipe string 80 on which the centralizer 8 is received. Expandable bow spring centralizer 8 may grip the expandable pipe string 80 when in the collapsed configuration to eliminate the need for a stop collar. Additionally or alternatively, a fin 32 may be connected to each bow spring 30, and then connected to one or more adjacent fins 32 upon collapse of the bow springs 30 to form a restraining band 39 that may be ruptured, e.g., upon expansion of the expandable pipe string 80.

摘要： A casing centralizer is provided that may be shipped unassembled and is then assemblable at a well site. According to one embodiment, first and second collars each have a plurality of circumferentially spaced aligning slots and a corresponding plurality of threaded, extruded through-holes. A plurality of bow-springs each have a foot at each end. Each bow-spring axially extends between the first and second collars. The foot at one end of each bow-spring is disposed in one of the aligning slots of the first collar, and the foot at the other end is disposed in one of the aligning slots on the second collar. A plurality of threaded fasteners corresponding in number to the threaded extruded through-holes secure the ends of the bow-springs to the threaded extruded through-holes. The extruded through-holes have a flange height greater than a collar thickness adjacent to the extruded through-holes. The increased flange height allows more threads to be formed within the extruded holes, resulting in a stronger threaded connection with the threaded fasteners, and a correspondingly stronger, more durable centralizer. The foot is retained within the aligning slot to reinforce the coupling between the bow-spring and the collar. A method of manufacturing the casing centralizer is also provided.
摘要翻译：提供一种套管扶正器，其可以被未组装运输，然后可以在井场装配。根据一个实施例，第一和第二轴环各自具有多个周向间隔开的对准槽和相应的多个螺纹的挤压通孔。多个弓弹簧各自在每一端具有脚。每个弓形弹簧在第一和第二轴环之间轴向地延伸。每个弓形弹簧的一端的脚设置在第一轴环的一个对准槽中，另一端的脚设置在第二轴环上的一个对准槽中。多个对应于螺纹挤压通孔的螺纹紧固件将弓形弹簧的端部固定到螺纹挤压通孔。挤出的通孔的凸缘高度大于与挤出的通孔相邻的套环厚度。增加的法兰高度允许在挤出的孔内形成更多的螺纹，导致与螺纹紧固件的更强的螺纹连接以及相应更坚固，更耐用的扶正器。脚保持在对准槽内，以加强弓弹簧和套环之间的联接。还提供了一种制造套管扶正器的方法。

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： A bow-spring centralizer includes a center assembly having a plurality of bow springs and a pair of generally tubular moving collars secured one to each end of each bow spring, the center assembly formed intermediate a pair of generally tubular stop collars. Each moving collar/stop collar combination forms an interlocking and axially extendable collar. The centralizer is formed from a single tube. The tube is cut using a laser according to a cut pattern that creates interlocked stop collar/moving collar combinations that are rotatably locked but axially movable one relative to the other. Each of the interlocked stop collars and moving collars includes a plurality of circumferentially spaced heads, each head integrally formed on one of a plurality of circumferentially spaced extensions protruding from the stop collar or moving collar. The heads may have a variety of projected shapes, such as a rectangular, arrow or a teardrop shaped. Each head is axially slidably captured within one of a plurality of chambers on the other tubular member (stop collar or moving collar) to which the first member is coupled. The extensions of each interlocked tubular member define the outer walls of the chamber in which a head of the opposing tubular member is slidably captured.

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.
