摘要： The present invention is directed to a segmented bottom guide for directing the top of a tubular member into and through a bore in the bottom of a tapered bowl so that the tubular member can be engaged by pipe slips. One embodiment of the segmented bottom guide of the present invention comprises a bottom guide retainer having a plurality of chambers for being disposed intermediate the top of a bell guide and the bottom of the tapered bowl. The bottom guide segments are radially received into, and securable in, the retainer to therein and together form a generally conical frustum generally aligned with and intermediate the top of the bell guide and the opening of the tapered bowl.

摘要： Embodiments of the present invention generally relate to an apparatus for supporting a tubular that more evenly distributes stress along the contact length of a tubular. In one embodiment, an apparatus for supporting a tubular is provided. The apparatus includes a bowl having a longitudinal opening extending therethrough and an inner surface for receiving a gripping member. The gripping member is movable along the surface of the bowl for engaging the tubular. The apparatus is configured so that an upper portion of the gripping member will engage the tubular before the rest of the gripping member engages the tubular.

摘要： A tubing hanger apparatus and method for installing coiled tubing in oil and gas wells utilizes a tubing head assembly having a vertical flow passage therethrough, a hydraulically operated piston in an upper portion of the flow passage; a double tapered slip cup and an annular packoff assembly in a lower portion of the flow passage, and a contractible double tapered slip assembly disposed between the piston and slip cup. The piston, in a normally raised position and the slip in a normally radially expanded position allows coiled tubing to be lowered or raised therethrough and through the slip cup and packoff assembly. The piston is lowered by hydraulic pressure to apply a vertical force that radially contracts the slip assembly to grip the tubing and support the weight thereof and the weight is transferred through the slip cup to expand the packoff assembly and seal the tubing.

摘要： The apparatus is connected to a member on the elevator that moves if and when the slips move between the open and closed positions. The member is locked in a preselected position that attends the position of the slips when the elevator is considered safe. When the member is in that safe position a wireless signal is generated by the apparatus part on the elevator and received by a receiving part of the apparatus in a convenient remote location such as the drillers position. In response to the received signal, the receiving part produces a visible signal to indicate that the slips are in the preselected position.

摘要： An apparatus for inserting or removing a string of tubulars from a borehole includes a makeup/break out mechanism which is capable of adding a tubular to or removing a tubular from the string and handling mechanism which feeds a tubular into, or removes a tubular from, the make up/break out mechanism. The make up/break out mechanism is moveable along the direction parallel to the axial direction of the string, such that the string may be substantially continuously inserted into or removed from the borehole.

摘要： A pipe pulling and pushing apparatus and method of operation, which apparatus includes a spring-loaded wedge device seated in a driving apparatus and fitted to a rod or pipe for forcing the rod or pipe beneath a road, pipeline or other barrier where trenching is not feasible. The spring-loaded wedge is characterized by a housing which receives a coil spring positioned to intermittently engage a wedge defined by wedge segments collectively having a rod bore and teeth for selectively gripping the rod or pipe when the spring is fully extended, and releasing the rod or pipe when the spring is compressed. Repetitive gripping and releasing of the rod or pipe by the wedge is effected responsive to operation of the driving apparatus to incrementally drive the rod or pipe through the terrain beneath the barrier. The spring-loaded wedge can also be positioned on the rod or pipe in the driving apparatus to pull the rod or pipe through the terrain beneath the barrier.

摘要： A die set used in pipe tongs in the oil and gas industry for gripping pipe while threadably coupling pipe joints, the die having electroless nickel plated, non-interrupted knurled teeth having a special shape which reduces die penetration, thereby reducing wall loss due to die penetration, stress cracking and carbon transfer to oil and gas field tubular pipe and especially to corrosive resistive alloy pipe, thus further reducing pipe corrosion.
