Description
Technical field
The present invention relates to oil and gas exploitation field, more particularly to a kind of oil pipe.
Background technology
Oil pipe is power tool necessary to exploitation oil and natural gas, typically in operation, hundreds of oil pipe is passed through
Threaded connection forms the tubing string up to thousands of meters, is recovered the oil in lower going-into-well cylinder.
When recovering the oil, generally oil well pump is connected to into oil pipe lower end, is lowered in pit shaft with oil pipe.In rod pumping pump
In oil extraction system, the sucker rod (most go up a section and claim polished rod) of oil well pump is connected with the horse head of the oil pumper on ground by hanger
Connect.During work, horse head drives sucker rod to move up and down by wire rope pulling hanger, completes operation of pumping.In upper undershoot
Under journey alternate load, in addition there is the reasons such as hole deviation, oily thick, wax deposition in oil well, and sucker rod can produce twisting in up and down motion process.
Particularly in the oil well using SAGD technologies, because SAGD oil wells are generally using oil well pump more than 120mm pumps footpath, therefore take out
Beam hanger can produce bigger twisting in up and down motion process, in order to prevent the twisting of sucker rod, generally using slotting in prior art
Connect formula sucker rod, but this have the consequence that the moment of torsion that sucker rod is twisted is discharged on oil pipe, moment of torsion acts on oil pipe connection
Place, to upper and lower oil pipe shackle power is formed, and so as to the junction of oil pipe occurs loosening in the presence of shackle power oil pipe Central Plains is caused
The leakage of oil, or even the junction of oil pipe causes the dropout of oil pipe in the presence of moment of torsion, affects the production of oil well.
The content of the invention
It is an object of the invention to provide a kind of oil pipe that can prevent junction from rotating.
The above-mentioned purpose of the present invention can be realized using following technical proposal:A kind of oil pipe, it includes:Lengthwise extend the
One oil pipe and the second oil pipe;With back to first end and the second end connector, the first end be used for and described first
Oil pipe is connected;It is formed with the side wall of the connector first recessed from the end face at second end to first concave end
Groove;Protrude the projection of the side wall of second oil pipe;The projection has opposed facing in the circumference of second oil pipe
First working face and the second working face;By first working face, second working face and with first working face and
The breach that the side wall of adjacent second oil pipe of second working face is formed;First groove can be simultaneously contained in
With the anti-twist body in the breach.
Preferably, it includes:The annulus fixed with the anti-rotation body phase, the annulus can be set in the connector or institute
State on projection, so that the anti-rotation physical efficiency is contained in first groove and the breach simultaneously.
Preferably, the annulus can be set on first oil pipe or second oil pipe, so that the anti-twist body
Can be contained in simultaneously in first groove and the breach.
Preferably, the side wall of second oil pipe and first working face and/or second work in the breach
An operating angle for being acute angle is formed with as face.
Preferably, it includes:Second oil pipe has near the connection end of the projection, and the connection end is used for and institute
The second end for stating connector is connected;The seal being sheathed on the connection end, the seal is used for when described second is oily
When pipe is connected with the connector, the seal is compressed between the connector and the projection.
The beneficial effect of a kind of oil pipe that the present invention is provided is:The present invention is first by first oil pipe and the of lengthwise extension
Two oil pipes;With back to first end and the second end connector, the first end be used for be connected with first oil pipe;
The first groove from the end face at second end to first concave end is formed with the side wall of the connector;Protrusion is described
The projection of the side wall of the second oil pipe;The projection have in the circumference of second oil pipe opposed facing first working face and
Second working face;Work by first working face, second working face and with first working face and described second
The breach that the side wall of adjacent second oil pipe in face is formed;Can be contained in simultaneously in first groove and the breach
Anti-twist body.Realize when the moment of torsion of sucker rod twisting is discharged on the first oil pipe and the second oil pipe, moment of torsion acts on connector
During with the junction of the second oil pipe, when forming shackle power to the junction, anti-twist body stretches into the first groove and breach simultaneously, so as to
So that the phenomenon that the junction of connector and the second oil pipe does not rotate in the presence of shackle power, oily so as to avoid first
Rotation between pipe and the second oil pipe, realizes the present invention and provides a kind of purpose of the oil pipe that can prevent junction from rotating;
Secondly by the annulus arranged with the fixation of anti-rotation body phase, the annulus can be set on connector or projection, so that anti-rotation physical efficiency
It is contained in first groove and the breach simultaneously, so as to avoid when anti-twist body is placed in the breach and the first groove
When, anti-twist body radially drops from the first groove or breach to the direction away from oil pipe side wall;Finally, the second oil pipe tool
There is the connection end of close projection, the seal being sheathed on connection end, seal is used for when the second oil pipe is connected with connector
When, seal is compressed between connector and projection, so as to increase the sealing of the junction of connector and the second oil pipe, is prevented
The leakage of the junction crude oil is stopped.
