摘要： In a method for slotting a pipe, a sacrificial liner is inserted into the pipe and radially expanded into contact against the inner pipe wall surface, whereupon rotating blades are plunged through the pipe wall and partially into the sacrificial liner. The sacrificial liner prevents the formation of wickers, and prevents cuttings and cutting fluid from entering the interior of the pipe, thus facilitating production of wicker-free slotted pipe requiring reduced post-slotting cleaning. An apparatus for implementing the method incorporates a fixed seal sub-assembly and a movable seal sub-assembly, interconnectable to form an elongate assembly which is adjustable to suit different pipe lengths. A cylindrical re-usable liner is disposable around the assembled fixed and movable seal sub- assemblies, and sized for insertion into the sacrificial liner. The re-usable liner may be expanded by internal pressure, thereby expanding the sacrificial liner. Preferably, the slotting method uses slotting blades with curvilinear teeth thinner than the main blade body, to produce cuttings that are narrower than the finished slot width, and therefore easier to remove from the slots during slotting operations.
摘要翻译：在用于开槽的方法中，将牺牲衬垫插入到管中并且径向扩张以与内管壁表面接触，于是旋转刀片穿过管壁并部分地插入到牺牲衬里中。牺牲衬垫防止木门的形成，并防止切屑和切削液进入管内，从而便于生产不需要减少后槽清洗的无柳条槽。用于实施该方法的装置包括固定密封子组件和可移动密封子组件，其可互连以形成可调整以适应不同管道长度的细长组件。圆柱形可重复使用的衬套围绕组装的固定和可移动密封子组件是一次性的，并且尺寸适于插入到牺牲衬垫中。可再利用的衬套可以通过内部压力膨胀，从而扩大牺牲衬里。优选地，开槽方法使用具有比主叶片本体更薄的曲线齿的开槽刀片，以产生比完成的槽宽度窄的切屑，因此在开槽操作期间更容易从槽中移除。

摘要： A fluid seal assembly consists of a seal element of compliant material that is retainingly carried by a seal carrier. The seal carrier includes one or more elements of relatively rigid material defining a sealing face with a seal-receiving groove interrupting the sealing face. The seal-receiving groove has groove-defining walls each of which has a proximal end at the sealing face and a distal end. The groove-defining walls serve as seal contact surfaces. The seal contact surfaces are configured such that the seal- receiving groove narrows toward its distal end. The seal-receiving groove has a depth and a breadth suitable for accepting the seal element, with the seal element projecting past the sealing face when compressed to be in contact with the seal contact surfaces.

摘要： An axially-floating sub tool for use with a top drive provides for axial load compensation by means of positive pressure or vacuum. The sub tool comprises a cylindrical upper member coaxially disposed within a cylindrical housing, with an upper section of the upper member slidably disposed within an opening in the upper end of the housing. The upper member also has a middle section that slidably and sealingly engages the cylindrical bore of the housing, plus a longitudinally-splined lower section. A cylindrical lower member has a cylindrical bore including a longitudinally-splined upper interval, and carries a coaxial stinger sealed to and extending upward from an annular shoulder in a medial region of the lower-member bore. The lower member is connected to the lower end of the housing with the stinger slidingly and sealingly disposed within the bore of the upper member, and with the splines on the upper interval of the lower- member bore slidingly engaging the splines on the lower section of the upper member, thus defining an upper annular chamber above the middle section of the upper member, a middle annular chamber between the middle section of the upper member and the upper end of the lower member, and a lower annular chamber between the lower end of the upper member and the shoulder on the lower member. The middle and lower annular chambers are in fluid communication, with a regulator/check valve being provided to regulate the pressure in the middle and lower annular chambers. The sub tool may optionally incorporate a passive compensator assembly mounted over the housing.

摘要： A cementing adaptor includes a cylindrical carrier carrying a casing seal, a middle interval and a lower end separated by an annular rib, and a cylindrical swivel element disposed around and coaxially rotatable relative to the middle interval. A cylindrical connector has an upper end rotatably disposed around the carrier's lower end and non- rotatably connected to the swivel element, plus a lower end connectable to an inner tubular string. With the carrier's upper end connected to a casing running tool (CRT), this assembly can be disposed within a casing string with the casing seal engaging the casing and preventing fluid flow into the casing annulus below the seal when cement is pumped down the inner string, such that the cement is urged into the wellbore annulus. The swivel connection limits torque transfer that might otherwise overload the CRT or its connection to the cementing adaptor.

摘要： A fluid management tool for introducing fluids into a casing string incorporates a mud saver valve configured to open and allow fluid flow in response to fluid flow pressure reaching a predetermined opening pressure, and will automatically close when fluid flow pressure is reduced to or below a predetermined closure pressure, thereby preventing fluid spillage when the tool is withdrawn from the casing. The mud saver valve includes a mud saver spool having a slotted spool cage and being axially movable within a longitudinal bore in the main body of the tool, between an upper or open position in which fluid can flow out of the spool cage and into a discharge bore at the lower end of the main body, and a lower or closed position in which the lower end is seated against the exit bore to prevent flow therethrough. A check valve may be incorporated into the lower end of the mud saver spool. The fluid management tool also may incorporate a main seal and air bleed valve subassembly and a secondary suction seal and check valve subassembly.
