摘要:
The present invention provides an apparatus and a method for lifting a single Joint of pipe. The single joint elevator of the present invention comprises, in one embodiment, a pair of deployable jaws cooperating with a pair of static jaws to secure a pipe within the slot of a generally horseshoe-shaped body. The deployable jaws of the single joint elevator of the present invention may be rotatably deployable or translatably employable, or both. In one embodiment, each jaw, including the static jaws and the deployable jaws, comprises a pipe slip movably disposed within the jaw to secure a pipe segment within the slot and to self-tighten as the weight of the pipe segment secured within the single joint elevator is transferred to the slips and the jaws.

Apparatuses and methods are disclosed herein relating to an apparatus to support a tubular member. The apparatus includes a bowl having a longitudinal axis extending therethrough, in which the bowl includes an inner wall formed about the longitudinal axis that is tapered with respect to the longitudinal axis. The apparatus further includes a plurality of slip assemblies movably disposed within to the bowl and having a tapered outer surface and a tapered inner surface with respect to the longitudinal axis. The tapered outer surface of the plurality of slip assemblies is configured to engage the tapered inner wall of the bowl. Further, the bowl may include a shoulder disposed on the inner wall that extends towards the longitudinal axis with respect to the inner wall. Each of the plurality of slip assemblies may be configured to engage the shoulder of the bowl.

A method and apparatus are provided for installing control lines and pipe into a well. The pipe-holding spider that is normally mounted on the rig floor is adapted for easy disassembly and reassembly when the pipe slips within the spider are not engaged with the outer surface of the pipe string so that upon disassembly, a control line guide becomes vertically movable. The control line guide is adapted for being controllably elevated to a distance above the rig floor, thereby providing personnel access to a portion of the length of the pipe string below the elevated control line guide and above the rig floor for securing control line to the pipe string using a fastener.

A magnetic anomaly detector at a selected location on a pipe string detects the passing of a pig carrying a permanent magnet. To distinguish between a number of pigs, the magnets are differently oriented, in terms of which magnetic pole passes the detector first. To distinguish between a number of magnet carrying pigs, the magnets are oriented such that a planned series of field changes occur in preferred order for each pig passing the detector.

A toothed pipe gripping die insert has textured surfaces on the die surface opposite the pipe gripping teeth to reduce the insert-to-insert carrier contact surface area to increase unit loading such that selected loads forcing the die insert against its carrier impresses the textured pattern into the carrier surface to reduce the tendency for the die insert to slide on the die carrier surface.

A method for running a tubular string in wellbore operations according to one or more aspects of the present disclosure includes providing a tubular running tool comprising gripping assembly rotationally connected to a carrier, the gripping assembly comprising a body and slips; connecting the carrier to a quill of a top drive of a drilling rig; positioning an end of a tubular for gripping with the slips; actuating the slips into gripping engagement with the tubular; and rotating the tubular with the slips in gripping engagement therewith.
摘要:
An apparatus to attach a control line to a tubular member, in which the apparatus includes a control line arm having a first control line guide coupled thereto, and a base having a second control line guide coupled thereto, with the control line arm coupled to the base and movable with respect to the base. The control line arm may be movable between a raised position and a collapsed position with respect to the base, and the control line arm may be at least one of slidably coupled and rotatably coupled to the base.

Apparatuses and methods to cut a control line and/or to run a control line on a rig may include a movable cutting apparatus to cut a control line, a load transfer member to engage a control line, a load measuring device to measure a load imparted to a load transfer member, and a drive member to engage and drive a control line. The apparatuses and methods may be used with a control line positioning apparatus, a pipe engaging apparatus, and/or may be used by themselves.

At least one sensor is mounted for monitoring the vertical position of an elevator relative to selected features on a pipe string. Mounting for a variety of sensor types is provided. Optional mounting arrangement permits the sensors to be situated close to a pipe free to move laterally, excess lateral movement of the pipe to move the mounting with reduced shock to the sensors.
