Description

Spinner apparatus

Technical field

The present invention relates to a kind ofly be used for connecting and dismounting tubular element (for example, sleeve pipe, oil pipe, pipe or drilling rod), some special aspect, relate to circulator, rotary spanner, rotary clamp, iron driller and their using method.

Background technology

During oil gas well drilling, the drilling rod of introducing in the well utilizes nipple to assemble along length.When pipe was infeeded in the well, pipeline section was screwed onto together.When shifting out pipe, the section of being spirally connected is disassembled and pipeline section is stored.Drill pipe section fill-in well neutralization shifted out from well be known as " making a trip ".When pipeline section being entered and shift out well, screw and the pipeline section of outwarding winding may be a difficulty and hard work.Set up and be threaded (perhaps outward winding or disconnect be threaded), need bigger moment of torsion (rotatory force).(or before jointing) makes pipeline section " rotation " need much smaller moment of torsion and finishes with much higher speed after break connector.Screwing with break connector needs spanner to be clamped on the pipe tightly.In early days, clamping and disconnection utilize hand-held spanner manually to finish (recently, utilizing the power-assisted spanner to finish).Rotation is a kind of lock out operation, long ago and now in some place, by chain being wrapped in around the pipe and utilizing winch to spur described chain and finish.Now, working power Pincers with spanner function.In these pincers some has the hydraulic power tongs that is used to manage the open slot of insertion and is used for pinch tube.Pipe is by the revolution that is mechanically attached to spanner.These spanners can produce high pulling torque and connect well and disconnect nipple.Usually, these spanners are worked with the auxiliary spanner of another section that keeps nipple.The clamping device of the so-called chuck in the base plate of oil gas platform shaft is mainly used in and prevents that tubing string from dropping in the well.Yet in some cases, chuck can be used as servicing unit and is used to form the moment of torsion that connects or disconnect the spanner that connects and rotate with opposing.Spanner is connecting or is disconnecting and removing after being threaded, and circulator (or top drive unit) joint that will be spirally connected is outwarded winding.United States Patent (USP) 4,348,920 have described the example of this spanner.Some types in these spanners lack the ability of the pipe of handling different-diameter under the situation that does not change pipe clamp.Because drilling rod, connector, conical pipe and joint have different-diameter, some spanners be widely applicable for diameter from about 9cm to about 25cm the diameter change of (3.5 to about 9.5 inches).For spanner, can adapt to the certain diameter scope under the situation that needn't change clamp is very big advantage.United States Patent (USP) 4,979,356 is examples of a Power Tong spanner, this Power Tong spanner not only can adapt to the pipe of wishing diameter range, but also can connect and disconnect pipeline section and make the pipe rotation.Utilize identical spanner to realize that above-mentioned two kinds of functions make us expecting very much, because it utilizes a Connection Step to need to utilize spanner and circulator to carry out twice or more times step of connecting before having realized.

People have used and will add torque wrench and be connected with " iron driller " that rotary spanner combines and dismantle various pipes, and drilling well parts for example such as drilling rod, make in drill string or other tubing string lower going-into-well or shift out from well.Prior art comprises various iron drillers; For example, referring to United States Patent (USP) 4,023,449; 4,348,920; 4,765,401; 6,776,070, at this all full patent texts are incorporated herein by reference.
