Description
Technical field
The present invention is the hoisting tool in oil field pumping well, is the oil pumping that oil pumping is connected between oil well pump and oil pumper
Bar, is a kind of reparation sucker rod.
Background technology
The well pumped with oil well pump wants tripping in sucker rod, and in use, some positions of its body of rod can quilt for sucker rod
Abrasion, corrosion.After some positions of these bodies of rod are suggested in the presence of the sucker rod for being worn, corroding in pumpingh well upkeep operation
It cannot again go into the well and use, existing oil pumping pole technology of repairing is that the sucker rod without abrasion, corrosion is repaired, and
There are abrasion, the sucker rod of corrosion to repair and have to scrap, cause the service life of sucker rod short, pumpingh well needs to change a large amount of
New sucker rod, production cost is high, and oil well is of poor benefits.
The content of the invention
The purpose of the present invention, which is that design is a kind of, repairs sucker rod, overcome above-mentioned problem, it is had abrasion, corrosion
Sucker rod can also be repaired and used again, reduce the learies of sucker rod, increase the use time of sucker rod, reduce oil well production cost.
The object of the present invention is achieved like this：Sucker rod to be repaired includes head portion, the body of rod, head portion, head portion, bar
Body, head portion are structure as a whole, and have the damaged section on damaged section, the excision body of rod on the body of rod, the body of rod is turned into the upper body of rod, lower beam
Body, the connecting pole on the lower end pier of the described upper body of rod goes out, lower connecting pole is gone out in the upper end pier of the described lower body of rod, will be described
Upper connecting pole is linked into an integrated entity with changing the upper end friction welding (FW) of bar, and described lower connecting pole is connected with changing the lower end friction welding (FW) of bar
It is connected into one.
Change diameter big one-level of the diameter than the body of rod of bar, described upper connecting pole, the diameter of lower connecting pole and replacing bar
Diameter it is identical.
The beneficial effects of the invention are as follows：The abrasion of sucker rod, corrosion section are replaced by intact replacing bar, make have abrasion, corruption
The sucker rod of erosion turns into the sucker rod that can be continuing with, it is to avoid has abrasion, the sucker rod of corrosion to scrap in advance, improves oil pumping
The service life of bar, adds the service life of sucker rod, it is possible to reduce the production cost of oil well, with significant economic effect
Benefit.
Brief description of the drawings
Fig. 1 is the structure chart of sucker rod to be repaired.Two-end structure is identical.
Fig. 2 is the structure chart after first step process when sucker rod to be repaired is repaired.
Fig. 3 is the structure chart after second step process when sucker rod to be repaired is repaired.
Fig. 4 is the structure chart after the completion of the present invention is repaired.
Embodiment
Illustrated with reference to pair embodiments of the invention of Fig. 1,2,3,4.
Embodiments of the invention are as shown in the figure.Sucker rod to be repaired is selected, as shown in figure 1, sucker rod to be repaired includes
Head portion 1, the body of rod 2, head portion 4, head portion 1, the body of rod 2, head portion 4 are structure as a whole, and have damaged section 3 on the body of rod 2.Cut off bar
Damaged section 3 on body 2, makes the body of rod 2 turn into upper body of rod 2-1, lower body of rod 2-2, as shown in Figure 2.Under described upper body of rod 2-1
End pier goes out upper connecting pole 2-3, and described upper connecting pole 2-3 and upper body of rod 2-1 is conical transition, reduces the factor of stress concentration,
Go out lower connecting pole 2-4 in described lower body of rod 2-2 upper end pier, described lower connecting pole 2-4 and lower body of rod 2-2 is conical mistake
Cross, reduce the factor of stress concentration, as shown in Figure 3.Described upper connecting pole 2-3 is connected with changing bar 2-5 upper end friction welding (FW)
Integrally, described lower connecting pole 2-4 is linked into an integrated entity with changing bar 2-5 lower end friction welding (FW), as shown in Figure 4.
Further measure of the invention is to change bar 2-5 diameter big one-level of the diameter than the body of rod 2, described upper company
It is identical with the diameter for changing bar 2-5 to connect post 2-3, lower connecting pole 2-4 diameter.The diameter of sucker rod is by oil and gas industry mark
Standard is determined, has Φ 16, Φ 19, Φ 22, Φ 25, Φ 28 etc. a variety of, if a diameter of Φ 22 of the body of rod 2, changes the straight of bar 2-5
Footpath is Φ 25.Increase bar can improve the usage cycles of sucker rod behind footpath.It is removed damaged section 3 to change bar 2-5 length
The positive and negative 1m of length, if the length of damaged section 3 is 4m, changes bar 2-5 length between 5m to 6m, it is ensured that after reparation
The length of sucker rod and the similar length of sucker rod to be repaired.
The size constancy of the two-end structure of sucker rod after reparation, the supporting connection of sucker rod that can be with same specification.
