摘要： One embodiment provides an adjustable guide (10a) to steer the end (90) of a pipe string (88) into position to be engaged and supported by a pipe gripping apparatus such as, for example, an externally gripping elevator assembly (10). The adjustable guide (10a) may comprise a plurality of distributed guide inserts (30), each having a sloped surface (3OA) to engage a pipe end (90). Another embodiment provides an adjustable guide (60a) to steer a pipe connection into position to pass through a spider (60). The guide inserts (30, 80) of an adjustable guide may be controllably positionable to together form a guide that is concentric with the bore of the tapered bowl of an elevator assembly or a spider. One embodiment comprises a guide insert retainer (11) having a plurality of channels (28), each slidably receiving a guide insert (30) and positionable by rotation of a threaded shaft (40).

摘要： A method for controlling the ascent and descent of a tubular member (11) passing through a pipe or casing slip (12) into a well bore. A float control member is affixed beneath the top surface of the pipe or casing slip. The control member is activated to control the raising or lowering of the tubular member. A piston within a cylinder housing is positioned below the top surface of the slip. As the tubular member is lowered, but before there is significant weight on the supporting structure, the piston is moved to its maximum height extension. Once the slips are set and the weight of the tubular member is applied to the slips, the piston begins to descend in the cylinder housing floating the final descent of the string. The string may be raised by activating a pump to force fluid within the housing chamber, raising the piston and thereby raising or lifting the string.

摘要： Method and apparatus for installing control lines (31) and pipe (14) into a well. The pipe-holding spider (11) that is normally mounted on the rig floor is supportably retained in a vertically movable retainer (12). The retainer is adapted for controllably elevating the spider above the rig floor when the pipe slips (24) within the spider are not engaged with the outer surface of the pipe string, thereby providing personnel access to a portion of the length of the pipe string below the elevated spider and above the rig floor. Personnel are provided with access to the pipe string for applying a fastener (34) to secure the control line to the pipe string. The control line is supplied from above the spider and is positioned by a control line guide (16) supported on the spider or retainer to pass through the spider outside the path of pipe gripping members within the spider.

摘要： A gripping apparatus (100) for supporting a tubular includes a longitudinal opening extending therethrough. A bowl (25) is formed on an inner wall of the housing to provide an incline surface for one or more gripping members (20). As the gripping members are move down along the incline, the incline causes the gripping members to move radially toward the tubular and contact the tubular. In one embodiment, the housing comprises two body portions (11, 12) coupled together using one or mores hinges (35). In one aspect, the bowl is formed as a recess in the inner wall (42) of the housing. The hinges of the housing are progressively curved to accommodate the recess bowl, thereby increasing the tubular size handling capacity of the gripping apparatus.

摘要： Die Erfindung betrifft einen Spannkopf für ein Gestängeelement mit Spannelementen zum Spannen des Gestängeelementes radial zu dessen Gestängeachse. Weiter sind eine Hubeinrichtung zum Erzeugen einer axialen Hubbewegung und ein Keilschiebermechanismus vorgesehen, durch welchen die axiale Hubbewegung in eine radiale Bewegung umsetzbar und auf die Spannelemente übertragbar ist. Ein robuster Aufbau wird dadurch erreicht, dass der Keilschiebermechanismus durch mindestens zwei Betätigungsstangen gebildet ist, welche in einem Grundkörper in schrägen Führungsbohrungen verschiebbar gelagert sind. Die Betätigungsstangen sind dabei an einem Ende mit der Hubeinrichtung verbunden und an einem anderen Ende sind die jeweils unmittelbar ein Spannelement angeordnet.

摘要： Slips (1, 21, 41) for engaging any jointed, coiled or flexible tubular with substantially no scoring, gouging or scraping, such as when supporting a drill string in a borehole or gripping a tubular (2, 22) during the connection or disconnection of a tool joint or pulling a cable or pipeline; additionally, applying a pre-determined minimum gripping force in order to avoid rotary slippage when the weight of the string is insufficient to achieve a conventional slips action; additionally, including a coarse wedge (30, 50) to take up the extra travel of a worn tool joint or a tubular of smaller diameter, with a means to ensure that the coarse wedge acts before the fine wedge (29, 49) does and a means to ensure that the wedging action remains if the actuating force is removed; additionally, including a secondary slips (40) to interfere with the upset on the tool joint to avoid relying on friction to support the string and a means of integrating this with the gripping slips and ensuring that the secondary slips act first; additionally, the application of these attributes 'upside down' to achieve the action of snubbing when forcing a tubular into compression instead of tension for any reason.

摘要： An elevator (13,25) for assembling a plurality of a large diameter pipe joints (11) into a pipe string with a drilling rig is disclosed. The first one of a number of large diameter pipe joints is adapted to threadingly engage another large diameter pipe joint. The elevator is detachably securable to the upper end of the first joint, and is adapted to both lift and position the first joint while it is stabbed and tightened onto the string. The elevator is further adapted to co-operatively engage the rotary table (24) of the drilling rig to rotatably tighten the second joint to the first joint as the second joint is added to the string.

摘要： A power tong set (9), with lead and back-up tongs (9a, b), is mounted on the slip bowl (7) of the traveling jack head (6) of a snubbing unit (2) and rotates with the slip bowl (7). Service lines (or umbelicals) for the tong set are not connected during string (ps) rotation. In an alternate version of the apparatus, a fluid feed through swivel (11) is mounted on the tong set (9), secured to the necessary tong operating and control service fluid line, or lines, such that the tong set (9) can rotate with tong service lines between the tong set (9) and the snubbing unit (2) during rotation. In an alternate form, the tong set (9) is mounted on the jack head (6), independently of the rotary table, and the tong set (9) does not rotate when the rotary table rotates.
