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 (1OA, 10B) comprise a plurality of slidably coupled links (16) that separate to expand the diameter of the collars (1OA, 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).
摘要翻译：（8），其具有通过多个弓形弹簧（30）联接到第二可膨胀套环（10B）并与第二可膨胀套环（10B）间隔开的第一可膨胀套环（10A），其中可膨胀套环（10A，10B）包括多个可滑动地联接的联接件（16），例如在其上接收扶正器（8）的可扩张管柱（80）扩张时，该联接件分开以扩张卡圈（10A，10B）的直径。当处于收缩构造时，可扩张弓形弹簧扶正器（8）可夹紧可扩张管柱（80）以消除对止动套环的需要。附加地或替代地，翅片（32）可以连接到每个弓形弹簧（30），并且随后在弓形弹簧（30）塌陷时连接到一个或多个相邻翅片（32）以形成限制带（39），例如在可膨胀管柱（80）膨胀时可能破裂。

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.
摘要翻译：使用包括以下步骤的方法来组装止动套环，所述方法包括：接收具有沿着管状物的外部延伸的一组指状物的基部的孔，将套筒的孔接收在邻近该组指状物的管状物上，并且接收套筒以干涉配合在手指组上。在替代实施例中，基部包括多个角度分布的指状物和/或基部包括间隙以允许基部与管状物一致。无指基座可以与一个或多个单独的手指配合以形成底座。在该方法的一个实施例中，套筒可以在将套筒接收到该组手指上的步骤之前进行热膨胀。可以在接收到该组手指之前加热套筒以使孔膨胀。

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.
摘要翻译：弓形弹簧扶正器（6）包括弓形弹簧（5），固定到每个弓形弹簧的每个端部的移动套环（11）和互锁止动套环（10）。可延伸的套圈（8）可以各自由可移动地与止动环（10）互锁的活动套环（11）形成。扶正器（6）可以可选地由使用激光器的管切割形成，以产生由弓形弹簧联接的两个可延伸的套环。每个可延伸的套环可以包括一体地形成在从套环（止动环或移动套环）突出的延伸部上的头部。头部通常可以是矩形，箭头或泪珠状的头部或其它形状。每个头部可以可滑动地被捕获在联锁套环（移动套环或止动套环）上的腔室内。每个互锁管状构件的延伸部限定了腔室的外壁，其中可互锁的管状构件的头部可滑动地被捕获。止动环可以包括或配合一个或多个手指，其沿着壳体延伸以由套筒固定以形成围绕套管的过盈配合。

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.
摘要翻译：在一个实施例中，耐磨带包括具有可接收在管状件上的孔的旋转元件，所述孔包括可滑动地接收第一和第二套筒轴承的第一和第二孔部分。套筒轴承的外表面可滑动地接合孔部分，并且套筒轴承的孔可滑动地接合管件。第一和第二止动环可以被容纳在管状件上，以一起跨越旋转元件和套筒轴承，以将旋转元件纵向固定在管状件上的位置。管状管可以包括在钻孔内的管状管柱中，或者进入安装的外壳的孔中，例如在钻孔时在套管中。旋转元件在管状件和孔的壁之间提供支撑，减小了对纵向滑动的摩擦阻力，并且还减小了管柱在孔内的旋转。
