Abstract
The utility model discloses a novel detachable sliding rail type inner flow sucker rod centralizer which comprises a first semi-cylindrical component, a second semi-cylindrical component, runner grooves, rail bosses, rail grooves and bolts. The axial end faces of the first semi-cylindrical component and the second semi-cylindrical component are respectively provided with the corresponding two axially-through runner rail grooves. The two radial end faces of the first semi-cylindrical component are respectively provided with the corresponding T-shaped sliding rail boss in an extending mode, and the two radial end faces of the second semi-cylindrical component are respectively provided with the corresponding T-shaped sliding rail groove corresponding to the corresponding rail boss of the first semi-cylindrical component. The first semi-cylindrical component and the second semi-cylindrical component are arranged on a sucker rod in a sleeved mode from the two sides. The novel detachable sliding rail type inner flow sucker rod centralizer is designed in a streamlined mode, the structure is simple, the flow guiding effect and the centralizing effect are good, field installation is convenient, the friction between the sucker rod and an oil pipe can be greatly reduced, the service life of the oil pipe and the sucker rod is prolonged, and the production cycle of an oil well is prolonged.
Description
Technical field
The utility model relates to a kind of oil extraction in oil field system mechanics equipment, especially relates to mobile oil pumping rod centering device in a kind of Novel dismountable slide rail type.
Background technology
In oil pumping in oil fields system, because can causing R a T, the existence of dog-leg has relative contact movement, between R a T, certainly existing and rubbing, there is the problem of sucker rod partial wear oil pipe, after producing eccentric wear, oil pipe and sucker rod mechanical property are reduced, very easily cause down-hole accident, harm oil well is normally produced, and affects crude oil yield.Therefore the problem that solves the eccentric wear between R a T is most important, current most solution is that erection device is installed on sucker rod, applying more is outer flow-guiding type centralizer, because the effective area of its water conservancy diversion is relatively little, and effectively wear-resistant surface is limited, makes its water conservancy diversion effect and righting effect not ideal enough.
Summary of the invention
In order to overcome shortcomings and deficiencies of the prior art, the utility model for sucker rod provide a kind of simple in structure, cost is lower, water conservancy diversion is effective, righting is effective, the on-the-spot easy for installation oil pumping rod centering device that flows in the detachable slide rail formula of wearing and tearing that can effectively reduce between sucker rod and oil pipe mutually.
To achieve these goals, the utility model adopts following technical scheme:
In a kind of Novel dismountable slide rail type, mobile oil pumping rod centering device, is to be mainly made up of semicircular cylinder member one, semicircle member two, flow path groove, track boss, orbital groove and bolt; On the axial end of semicircular cylinder member one and semicircular cylinder member two, all have two flow path grooves that axially connect, on two radial end faces of semicircular cylinder member one, be respectively extended with the slide rail boss of a T-shape, on two radial end faces of semicircular cylinder member two, have the T-shape sliding rail groove corresponding with the slide rail boss of semicircular cylinder member one; Semicircular cylinder member one and semicircular cylinder member two are enclosed within sucker rod from both sides, are tightly fixed on sucker rod by agreeing with between slide rail boss and sliding rail groove; And with the slippage between bolt restriction semicircular cylinder member one and semicircular cylinder member two.
The utility model is owing to taking above technical scheme, and it has the following advantages:
1, the utility model can, according to on-site actual situations, freely be adjusted the distance between each centralizer, makes sucker rod placed in the middle in oil pipe, greatly reduces the friction between the R a T at dog-leg place.
2, the utility model is simple in structure, and on-the-spot easy for installation quick, material is nylon material, and not perishable and damage, can reuse.
This centralizer is airflow design, simple in structure, and water conservancy diversion effect and righting effect are all good, on-the-spot easy for installation, can greatly reduce the friction between sucker rod and oil pipe, improve the application life of oil pipe and sucker rod, extend the oil well production cycle.

Detailed description of the invention
Below in conjunction with accompanying drawing, concrete enforcement of the present utility model is further described.
The utility model is mainly made up of semicircular cylinder member 1, semicircle member 22, flow path groove 3, track boss 4, bolt 5 and orbital groove 6; On the axial end of semicircular cylinder member 1 and semicircular cylinder member 22, all have two flow path grooves 3 that axially connect.On two radial end faces of semicircular cylinder member 1, be respectively extended with the slide rail boss 4 of a T-shape, on two radial end faces of semicircular cylinder member 22, all have the T-shape sliding rail groove 6 corresponding with the slide rail boss 4 of semicircular cylinder member 1; And 6 have corresponding bolt hole 7 on slide rail boss 4 and sliding rail groove.The axial both ends of the surface of semicircular cylinder member 1 and semicircular cylinder member 23 adopt domatic design, can effectively facilitate sucker rod transfer and on carry.Semicircular cylinder member 1 and semicircular cylinder member 22 are enclosed within sucker rod from both sides, are tightly fixed on sucker rod by agreeing with between slide rail boss 4 and sliding rail groove 6; And limit the slippage between semicircular cylinder member 1 and semicircular cylinder member 22 with bolt 5, complete the installation of this centralizer.
After centralizer installs, according to on-site actual situations, can carry out the number of suitable increase centralizer at the serious place of dog-leg, guarantee the centre position of sucker rod in oil pipe, make the friction between sucker rod and oil pipe be down to minimum.In addition, the utility model material is elected nylon material as, has high temperature resistant, wear-resistant, corrosion resistant great enhancing its application life.
