Abstract
The utility model provides a kind of anticorrosive abrasion-proof sucker rod centralizer with supporting positive cover, including columned centralizer body, the center of centralizer body is equipped with the through hole of installation sucker rod, some elastic mechanisms are circumferentially equipped with through hole, the outer surface of centralizer body is equipped with corrosion resisting alloy coating, the outer surface of corrosion resisting alloy coating is equipped with upper supporting positive cover, lower supporting positive cover and some centralizer rib bodies, some centralizer rib bodies are alternately welded with cemented carbide material and spherical roller between upper supporting positive cover and lower supporting positive cover on some centralizer rib bodies.The setting of supporting positive cover and lower supporting positive cover can effectively prevent the eccentric wear of sucker rod on the utility model, reduce the rate of depreciation of sucker rod；And the setting of corrosion resisting alloy coating and centralizer rib body can improve the anticorrosion antiwear performance of centralizer, extend its service life.
Description
Technical field
Centralizer technical field is the utility model is related to, more particularly to a kind of anticorrosive abrasion-proof sucker rod with supporting positive cover is helped
Positive device.
Background technology
At present, not only the well liquid in oil-field thick-oil, thin oil, high solidifying oily development and production because the thing such as High water cut, high salinity
Physical chemistry characteristic can cause oil well rod and tube partial-wear, seriously corroded, and the unreasonable of casing programme can also cause rod and tube partial-wear.Take out
It will cause rod broken during beam hanger eccentric wear seriously corroded, and cause oil well output to reduce or even can not exploit and easily trigger safe thing
Therefore.Existing oil pumping rod centering device friction phenomenon is serious, and itself without anticorrosion antiwear act on, during use easily by
Corrosive wear, reduces its service life.
The content of the invention
The utility model is exactly to be directed to above technical problem, there is provided a kind of anticorrosive abrasion-proof sucker rod righting with supporting positive cover
Device.
The utility model to achieve the above object, using following technical scheme：A kind of anticorrosion antiwear with supporting positive cover is taken out
Beam centralizer, including columned centralizer body, the center of centralizer body are equipped with the through hole of installation sucker rod, on through hole
Circumferentially it is equipped with some elastic mechanisms, the outer surface of centralizer body is Ni equipped with material60The corrosion resisting alloy coating of A, corrosion resistant
The outer surface of erosion alloy coat is equipped with upper supporting positive cover, lower supporting positive cover and some centralizer rib bodies, and some centralizer rib bodies are positioned at upper
Between supporting positive cover and lower supporting positive cover, alternately cemented carbide material and spherical roller are welded with some centralizer rib bodies.
The elastic mechanism uses arcuate bombing leaf, and the both ends of arcuate bombing leaf are fixed on the inner walls of the via.
The centralizer rib body is in the shape of a spiral.
The upper supporting positive cover is nested with to be nested with the outer surface of the upper end corrosion resisting alloy coating of centralizer body, lower supporting positive cover
In the outer surface of the lower end corrosion resisting alloy coating of centralizer body.
Compared with prior art, the beneficial effects of the utility model are：Supporting positive cover and lower supporting positive cover on the utility model
The eccentric wear of sucker rod can effectively be prevented by setting, and reduce the rate of depreciation of sucker rod；And corrosion resisting alloy coating and centralizer
The setting of rib body can improve the anticorrosion antiwear performance of centralizer, extend its service life.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
In figure：1st, centralizer body；2nd, through hole；3rd, elastic mechanism；4th, corrosion resisting alloy coating；5th, upper supporting positive cover；6th, under
Supporting positive cover；7th, centralizer rib body；8th, cemented carbide material；9th, spherical roller.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Figure 1, a kind of anticorrosive abrasion-proof sucker rod centralizer with supporting positive cover, including columned centralizer body
1, the center of centralizer body 1 is equipped with the through hole 2 of installation sucker rod, and some elastic mechanisms 3, righting are circumferentially equipped with through hole 2
The outer surface of device body 1 is Ni equipped with material60The corrosion resisting alloy coating 4 of A, the outer surface of corrosion resisting alloy coating 4 is equipped with upper
Supporting positive cover 5, lower supporting positive cover 6 and some centralizer rib bodies 7, some centralizer rib bodies 7 be located at upper supporting positive cover 5 and lower supporting positive cover 6 it
Between, alternately it is welded with cemented carbide material 8 and spherical roller 9 on some centralizer rib bodies 7.
The elastic mechanism 3 uses arcuate bombing leaf, and the both ends of arcuate bombing leaf are fixed on the inner wall of through hole 2.
The centralizer rib body 7 is in the shape of a spiral.
The upper supporting positive cover 5 is nested with the outer surface of the upper end corrosion resisting alloy coating 4 of centralizer body 1, lower supporting positive cover 6
It is nested with the outer surface of the lower end corrosion resisting alloy coating 4 of centralizer body 1.
The upper supporting positive cover 5 and lower supporting positive cover 6 that the utility model is set can carry out righting to sucker rod, effectively prevent from pumping
The eccentric wear of bar, reduces the rate of depreciation of sucker rod；The setting of corrosion resisting alloy coating 4 can improve the antiseptic property of centralizer,
The setting of cemented carbide material 8 improves the wear-resisting property of centralizer, and spherical roller 9 reduces resistance when centralizer enters deep-well
Power, improves construction efficiency；And the setting of elastic mechanism 3 may be such that centralizer is stuck in the optional position of sucker rod, user
Just it is quick.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model implement and from
The limitation of aforesaid way, if the various improvement that the methodology of the utility model and technical solution carry out are employed, or without
Improvement directly applies to other occasions, within the scope of protection of the utility model.
