Abstract
The utility model provides an anti-offset wear stabilizer of the independent wear-resistant stripped sucker rod. The utility model mainly solves the problem that after the local parts of the existing stabilizer and the anti-offset wear coupling are worn, only the entirety is replaced. The utility model is characterized in that straight type independent wear-resistant strips (3) are fixed through bolts (4) outside a sucker rod coupling (1). Not only in the anti-offset wear stabilizer of the independent wear-resistant stripped sucker rod the independent wear-resistant strips can be replaced solely, but also the anti-offset wear stabilizer of the independent wear-resistant stripped sucker rod has the characteristics of low cost, simple structure and convenient installation.
Description
Technical field:
The utility model relates to the used down-hole accessory in oil recovery field, oil field, especially independent wear rib formula sucker rod deflection abrasion preventing centralizer.
Background technology:
At present along with the deepening continuously of oil field development, pumping production extensively utilizes in the oil field.And when driving the sucker rod repeating motion by oil pumper, the generation eccentric wear phenomenon ubiquity of sucker rod and well head and oil pipe.In order to solve the eccentric wear problem, mostly adopt the mode of centralizer being installed on sucker rod or setting upright box cupling to prevent eccentric wear on the present oil field.And existing centralizer and set upright box cupling all exists and sets upright after the concentrated wear of wear-resisting position the shortcoming of must integral replacing and can't change separately the part, has caused very big material consumption and waste, and cost of production is increased.
The utility model content:
For deficiency that can only integral replacing after overcoming existing centralizer and setting upright the box cupling concentrated wear, the utility model provides a kind of independent wear rib formula sucker rod deflection abrasion preventing centralizer.The not only independent wear rib of this independent wear rib formula sucker rod deflection abrasion preventing centralizer can be changed separately, and has cost characteristics low, simple in structure and easy for installation.
The technical solution of the utility model is: this independent wear rib formula sucker rod deflection abrasion preventing centralizer comprises rod collar, and rod collar is outer to have straight shape independence wear rib by screw.
Rod collar in the such scheme or be sucker rod or centering ring; Independent wear rib or be fixed in the outer groove of rod collar; Independent wear rib or be connected rod collar by molding or interlocking or pin (riveting) nail; The outer counterbore of screw is built-in with chock; Independent wear rib is built-in with metallic framework; Independent wear rib or be ring-type or helical form.
The beneficial effect that the utlity model has is: this independent wear rib formula sucker rod deflection abrasion preventing centralizer is owing to adopted such scheme, outside rod collar, be fixed with independent wear rib, behind some independent wear rib wear out failures, can change separately, thereby solved the problem that the centralizer concentrated wear can only the integral replacing waste material, and cost is low, simple in structure, easy for installation, effectively reduce production costs.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the structural representations for rod collar;
Accompanying drawing 3 is the structural representations for sucker rod.
1-rod collar among the figure, 2-groove, 3-independence wear rib, 4-screw, 5-chock.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
Embodiment 1
By shown in Figure 1, this independent wear rib formula sucker rod deflection abrasion preventing centralizer comprises rod collar 1, is fixed with straight shape independence wear rib 3 by screw 4 outside the rod collar 1.Because after some independent wear rib 1 wearing and tearing, can will change separately like a cork by knockout screw 4 at the scene, thereby solved existing centralizer and set upright the problem that the box cupling concentrated wear can only integral replacing, and alleviate labor strength, reduce the activity duration, increase work efficiency, simple in structure, easy for installation, effectively reduce production costs.
Embodiment 2
By shown in Figure 1, this independent wear rib formula sucker rod deflection abrasion preventing centralizer comprises rod collar 1, is fixed with straight shape independence wear rib 3 by screw 4 outside sucker rod or the centering ring 1.Because independent wear rib 3 can be fixed on the sucker rod by screw 4, also can play centralizing function to sucker rod, reduced cost, improve and set upright effect.
Embodiment 3
By shown in Figure 1, this independent wear rib formula sucker rod deflection abrasion preventing centralizer comprises rod collar 1, is fixed with straight shape independence wear rib 3 by screw 4 in the groove 2 outside the rod collar 1.Because groove 2 can be reinforced independent wear rib 3, make independent wear rib 3 fix better.
Embodiment 4
By shown in Figure 1, this independent wear rib formula sucker rod deflection abrasion preventing centralizer comprises rod collar 1, is fixed with straight shape independence wear rib 3 outside the rod collar 1 or by interlocking or pin (riveting) nail.Because also independent wear rib 3 can be fixed on the rod collar 1 by interlocking or pin (riveting) nail, reach same effect.
Embodiment 5
By shown in Figure 1, this independent wear rib formula sucker rod deflection abrasion preventing centralizer comprises rod collar 1, is fixed with straight shape independence wear rib 3 by screw 4 outside the rod collar 1, and screw 4 outer counterbores are built-in with chock 5.Because restriction screw 4 that can certain limit is loosening, the safety that has further improved centralizer.
Embodiment 6
By shown in Figure 1, this independent wear rib formula sucker rod deflection abrasion preventing centralizer comprises rod collar 1, is fixed with straight shape independence wear rib 3 by screw 4 outside the rod collar 1, and independent wear rib 3 is built-in with metallic framework.Because metallic framework can strengthen the intensity of independent wear rib 3, prolong the operating period of independent wear rib 3.
Embodiment 7
By shown in Figure 1, this independent wear rib formula sucker rod deflection abrasion preventing centralizer comprises rod collar 1, is fixed with ring-type or helical form independence wear rib 3 by screw 4 outside the rod collar 1.Because ring-type or helical form independence wear rib 3 also can play the effect of anti-eccentric wear.
In sum, behind some independent wear rib wear out failures, can change separately, from And solved the problem that the centralizer concentrated wear can only integral replacing waste material and cost Low, simple in structure, easy for installation, effectively reduce production costs. This independent wear rib thus The formula Anti-grinding centering guide of sucker rod has cost characteristics low, simple in structure and easy for installation.
