摘要： The present invention generally relates to a pipe handling system for use with a tubular joining system (such as a welding or forging assembly) located on a drilling rig at a wellbore. In one aspect, a method of forming a string of pipe using a joining assembly at a wellbore is provided. The joining assembly includes an internal joining tool and an external joining tool. The method includes the step of picking up the pipe joint using an elevator. The method further includes the step of positioning a lower end of the pipe joint adjacent an end of a string of pipe disposed in the external joining tool. The method also includes the step of moving the internal joining tool from a first position to a second position relative to the elevator, wherein the second position is between the pipe joint and the string of pipe. The method further includes the step of forming a connection between the pipe joint and the string of pipe. The method further includes the step of gripping the pipe joint with a gripping tool and releasing the elevator from the pipe joint. Additionally, the method includes the step of lowering the pipe joint and the string of pipe into the wellbore. In another aspect, a method of forming a string of pipe using a joining assembly on a rig is provided. In a further aspect, a pipe handling system for locating a pipe joint in a joining assembly that includes an internal joining tool and an external joining tool is provided.

摘要： An oilfield elevator is disclosed and has first and second body halves pivotally-coupled at a hinge and moveable between an open position and a closed position to receive and move a tubular segment. Slips are slidably received within corresponding tapered slots in the elevator and are configured to translate vertically within the tapered slots and, at the same time, radially so as to be able to capture a wider range of tubular having varied outside diameters. Tension handles are pivotally-coupled to the first and second body halves and moveable between locked and unlocked positions. Locking the tension handles engages the slips via biasing members, and forces the slips into radial contact with the tubular segment. Unlocking the tension handles releases the biasing members.

摘要： A method of making up and running a pipe string (88) into a borehole comprising the steps of: providing a spider (60) supported on a rig and having at least one slip (67) movably received within and co-operating with a smooth, non-stepped tapered bowl (71) within the spider; providing an elevator assembly (100) movably supported above the spider and having at least one slip (117) movably received within and co-operating with a smooth, non-stepped tapered bowl (121) within the elevator assembly; supporting a first portion of a pipe string (88a) having a first diameter using the spider; joining an additional pipe segment (88b) having a second diameter to a proximal end of the first pipe segment to form the pipe string having at least one outer diameter transition along is length; and supporting the pipe string using the spider. 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 (100). The adjustable guide (10a) may comprise a plurality of distributed guide inserts (30), each having a sloped surface (30A) 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).
