Description
Technical field
The present invention relates to oil recovery aid field, more particularly to a kind of natural gas based on many switching at runtime processes is pumped
Normal state systems stabilisation.
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 and horizontal power to centralizer, from
And centralizer is hampered impact, common centralizer can not reduce the both direction resistance being subject to, in the presence of frictional force, cause
Centralizer service life is short, and is easily damaged sucker rod, and general rolling wheel centralizer is due to the limitation of roller rotating direction, nothing
Method eliminates the transverse component produced, and resistance is big, easy damaged sucker rod.
The content of the invention
The present invention is in order to overcome existing oil pumping rod centering device presence can not eliminate or effectively reduce the water that centralizer is subject to
The resistance of gentle vertical direction, causes centralizer service life short, and the easily damaged defect of sucker rod is helped there is provided a kind of sucker rod
Positive device, 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 natural gas based on many switching at runtime processes is pumped and set in the middle part of normal state systems stabilisation, including core body, core body
There is centralizer body, centralizer body external diameter is more than sucker rod external diameter；Centralizer body includes outer barrel and cover plate；Its outer barrel surface is provided with righting
Tumbler is provided with block, wiper block；Cover plate is arranged on centralizer body two ends；Tumbler includes ball, groove, auxiliary ball, limit
Position cover plate and ball retainer；Groove is arranged on wiper block, and auxiliary ball is separately positioned on the bottom and four sides of groove, passes through
Ball retainer is fixed, and and ball contact, in a groove, its top is protruded to be provided with groove, spacing cover plate for ball setting
Circular hole, Circularhole diameter is less than the diameter of ball.
The ball of tumbler can allow centralizer to be moved up and down with sucker rod work, and the setting of auxiliary ball can then allow
Roll carry out any direction rotation, such as centralizer simultaneously by vertically and horizontally resistance when, it can also be ensured that centralizer body is being done
Moved in a circle while vertical movement.
Further, the diameter parallel of wiper block is in core body axis, and wiper block is uniformly distributed along outer barrel circumferencial direction, it is ensured that helped
Positive device energy uniform stressed, stable sucker rod.
It is preferred that, tumbler is along outer barrel circumferencial direction at least provided with 3 groups, and every group of tumbler is at least 1, and at least 3 groups turn
Moving part ensure that centralizer can be contacted in pipe circumference direction with even tube wall, increase the stablizing effect of centralizer.
Further, the two ends of outer barrel are also respectively provided with limited impression, and cover plate is embedded in centralizer body two ends by limited impression
Outer barrel and core body between, for sealed outer cylinder and core body.
The present invention has the following advantages compared with prior art：
When the present invention is applied, ball can carry out the rotation of any direction, can eliminate the same of part vertical direction resistance
When absorb the power of horizontal direction, substantially reduce the frictional force that centralizer is subject to, extend centralizer service life, it is effective to protect
Sucker rod is protected.
Brief description of the drawings
