Description
Technical field
The present invention relates to oil recovery aid field, more particularly to a kind of normal state stabilising arrangement of oil gas pumping system.
Background technology
At present, oil pumping rod centering device is widely used in oil well acquisition, is the downhole tool of anti-sucker rod partial wear, it is adaptable to partially
The rod-pumped well of mill, the rod-pumped well and deviated directional drilling of the sucker rod point of neutralization above eccentric wear that is particularly suitable for use in, the sucker rod point of neutralization
Hereinafter, coordinate with the nylon centralising device on the oil pumping body of rod, eccentric abrasion prevention is better.Sucker rod is up and down in oil pipe, due to
The elastic deformation of sucker rod, bar and tubing wall easily produce friction, and sucker rod is easily disconnected de-, and oil pumping rod centering device has pliability
By force, it is contacted with tube inner wall, it is possible to reduce the friction of bar and pipe, strengthens the oil recovery life-span of oil pumper.Centralizer, which is connected to, to be taken out
On beam hanger, it is more than rod collar external diameter using the external diameter of supporting positive cover and plays centralizing function；It is high-strength abrasion-proof material using supporting positive cover
Material, being contacted with oil pipe makes centralizer body wear and tear, and reduces the abrasion of oil pipe, to reach the purpose of eccentric abrasion prevention.
During oil extraction operation, the activity of sucker rod makes oil pipe produce certain vertical force to centralizer, so that righting
Device is hampered impact, and common centralizer can not reduce the resistance being subject to, in the presence of frictional force, cause centralizer service life
It is short, and easily it is damaged sucker rod.
The content of the invention
In order to overcome existing oil pumping rod centering device presence can not eliminate or effectively reduce, centralizer is subject to the present invention hangs down
Nogata to resistance, cause centralizer service life short, there is provided a kind of oil gas pumping system for the easily damaged defect of sucker rod
Normal state stabilising arrangement, can effectively reduce the resistance that centralizer is subject in oil extraction operation, improve centralizer service life, more effectively
Protect sucker rod.
To achieve the above objectives, the present invention is adopted the following technical scheme that：
A kind of normal state stabilising arrangement of oil gas pumping system, including core body, core body are provided at both ends with the middle part of interface, core body and set
It is equipped with centralizer body；Centralizer body external diameter is more than sucker rod external diameter；Centralizer body includes outer barrel, inner cylinder and cover plate；Outer barrel surface is provided with
Set fluted on wiper block, wiper block, groove is uniformly distributed along wiper block axis；Roller, roller are additionally provided with wiper block
Longitudinally disposed in a groove along wiper block, roller protrudes from wiper block；The quantity of the cover plate is two pieces, the cover plate described in two pieces
It is separately positioned on centralizer body two ends.When the present invention is applied, it is vertical with tube wall that the roller on centralizer body can effectively reduce centralizer body
Frictional force, can effectively eliminate the power for the vertical direction that part sucker rod is produced, reduce the loss of centralizer, extending it makes
Use the life-span.
Further, the diameter parallel of wiper block is in the core body axis, and wiper block uniformly divides along the outer barrel circumferencial direction
Cloth, centralizer energy uniform stressed, it is to avoid too fast loss.
Further, groove is along the outer barrel circumferencial direction at least provided with 3 groups, and every group is at least 2.
Further, the two ends of the outer barrel are provided with limited impression, and the cover plate is located between outer barrel and inner cylinder, and embedding
Enter in limited impression.Wherein, cover plate is closed to centralizer body.
In summary, the invention has the advantages that：Overall structure of the present invention is simple, is easy to implement, cost is low, this
The outer barrel surface of invention is provided with wiper block, wiper block and sets fluted, and groove is uniformly distributed along wiper block axis, wiper block
On be additionally provided with roller, roller is longitudinally disposed in a groove along wiper block, and roller protrudes from wiper block, is made by vertical force
Used time, rolled by roller, eliminate the vertical stress in part, substantially reduce the resistance that centralizer is subject to, extending centralizer makes
With the life-span, sucker rod is effectively protected.

Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, with reference to embodiment and accompanying drawing, to this
Invention is described in further detail, and exemplary embodiment and its explanation of the invention is only used for explaining the present invention, does not make
For limitation of the invention.
Embodiment
As shown in Figures 1 and 2, a kind of normal state stabilising arrangement of oil gas pumping system, including core body 1, the two ends of core body 1 difference
Interface 3 is provided with, the middle part of core body 1 is provided with centralizer body 2；During work, connected respectively with two ends sucker rod by the interface 3 at two ends
Connect, wiper block 22 is uniformly distributed along the circumferencial direction of outer barrel 23.The two ends of outer barrel 23 are provided with limited impression 27, and cover plate 28 is located at
Between outer barrel 23 and inner cylinder 24, and in embedded limited impression 27.The quantity of the present embodiment cover plate 28 is two pieces, two cover plates 28
It is separately positioned on the two ends of centralizer body 2.Because centralizer external diameter is more than sucker rod external diameter, centralizer plays stable center to sucker rod
