Description
Technical field
The utility model belongs to OFME technical field, more particularly, to a kind of helping for interior flowing sucker rod
Positive device.
Background technology
In oil field operation, friction is certainly existed between R a T, sucker rod meeting eccentrically worn tubing is produced after eccentric wear
So that oil pipe and the reduction of sucker rod mechanical property, easily cause down-hole accident, harm oil well is normally produced, and influences crude quality,
Therefore, solve the problems, such as that the eccentric wear between R a T is most important, the method solved mostly at present is pacified on sucker rod
Centralizer is filled, existing centralizer installation and removal are inconvenient, and water conservancy diversion effect is undesirable.
The content of the invention
In view of this, the utility model is directed to a kind of centralizer for interior flowing sucker rod, with easy disassembly, carries
The stability and water conservancy diversion efficiency of high water conservancy diversion.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
A kind of centralizer for interior flowing sucker rod, including first component, second component, fixture, guiding gutter, projection
And groove, the first component and second component are in be respectively equipped with axle on the outside of semi-cylindrical, the first component and second component
To the guiding gutter of insertion, projection of the radial end face provided with axial direction of the first component, the radial end face of the second component
Be provided with the groove coordinated with projection, the first component and second component are provided with fixture, the fixture by lock ring and
Lock composition, the lock ring is set on the first part, and the lock is located on second component.
Further, it is respectively equipped with two or more guiding gutter on the first component and second component.
Further, the first component is provided with four lock rings, and second component is provided with corresponding with lock ring position
Four locks.
Relative to prior art, a kind of centralizer for interior flowing sucker rod described in the utility model has following excellent
Gesture：
Centralizer structure of the present invention is simple, reasonable in design, is easy for installation and removal, stability maintenance is good, outside
Provided with guiding gutter, water conservancy diversion efficiency high, stability are good, greatly reduce the friction between R a T, extend sucker rod
With the service life of oil pipe, it is ensured that the production cycle of underground.

Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
It is a kind of for it is interior flowing sucker rod centralizer, including first component 1, second component 2, fixture 3, guiding gutter 4,
Projection 5 and groove 6, the first component 1 and second component 2 are in semi-cylindrical, the first component 1 and the outside of second component 2
Be respectively equipped with axially through guiding gutter 4, be respectively equipped with two guiding gutters 4 in the first component 1 and second component 2, it is described
Projection 5 of the radial end face of first component 1 provided with axial direction, the radial end face of the second component 2 is provided with to be coordinated with projection 5
Groove 6, the first component 1 and second component 2 be provided with fixture 3, and the fixture 3 is by 32 groups of lock ring 31 and lock
Into the lock ring 31 is located at the top and bottom of first component 1, and the lock ring is provided with four, and the lock 32 is located at second component 2
Top and bottom, the position with lock ring 31 is corresponding, and lock 32 is provided with four.
The course of work of the present embodiment：In use, first component 1 and second component 2 are enclosed on sucker rod from both sides
On, it is fixed on by the cooperation between projection 5, groove 6 and lock 32 on sucker rod, completes the installation of centralizer, centralizer peace
Install after finishing, the quantity that can increase centralizer according to actual conditions ensures that sucker rod is in the centre position of oil pipe, makes sucker rod
Friction between oil pipe is minimized.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
