Abstract
The utility model provides a rotating centralizer for pumping rod, relating to an improved localizer structure for pumping rod centralizer used on pumping well. The utility model comprises two hemicycle shaft sleeves (1) and two elastic retainer rings (2). A rotor (3) is fixed on the curved surfaces of each of the hemicycle shaft sleeves (1), and a groove (4) for retainer ring is arranged at the top and bottom ends of each curved surface of the hemicycle shaft sleeves (1), with the planes of the hemicycle shaft sleeves (1) corresponding to each other. The two elastic retainer rings (2) are fixed in the groove (4) for retainer ring on the hemicycle shaft sleeves (1). The planes of the two hemicycle shaft sleeves (1) in the utility model buckle correspondingly between the two localizers on the pumping rod, with the elastic retainer rings (2) tightly buckling up the two hemicycle shaft sleeves (1). So as the pumping rod works, the utility model moves upward and downward, and driven by oil flow, the rotor drives the centralizer to rotate without changing the contact surface of the centralizer and the internal wall of the well pipe. The utility model has the advantages of simple structure and rapid assembly; and can effectively avoid eccentric wear, lengthen the service life of the centralizer, and improve the economic benefits of the well.
Description
Technical field: the utility model relates to the improvement of oil field pumping well oil pumping rod centering device structure.
Background technology: existing oil pumping rod centering device all is straight wing or wheeled construction, because these centralizers are fixed on the sucker rod, the wing on the centralizer or wheel are all the time facing to a line on the well casing inwall, inclined shaft particularly, the eccentric wear especially severe of centralizer, the well casing inwall also can cause uneven wear, and changing centralizer will influence oil well yield, the life cycle of centralizer is short more, and is big more to the benefit influence in oil field.
The utility model content: the purpose of this utility model is a kind of sucker rod of a development rotation centralizer, it have simple in structure, quick for installation, can on sucker rod, rotate, centralizer can effectively prevent eccentric wear, prolongs life cycle, improves the characteristics of well recovery benefit.The utility model is made up of two semicircle axle sleeves 1 and two circlips 2, be fixed with rotor 3 on the curved surface of each semicircle axle sleeve 1, the two ends up and down of semicircle axle sleeve 1 curved surface have circlip groove 4, the plane of two semicircle axle sleeves 1 is relative, and two elastic rings 2 are fixed in the circlip groove 4 of two semicircle axle sleeves 1.The utility model is buckled in the plane of two semicircle axle sleeves 1 the locator upper end on the sucker rod in use relatively, with circlip 2 two semicircle axle sleeves 1 are buckled together tightly, when sucker rod is worked, move up and down with sucker rod, under the effect of oil stream, rotor can drive centralizer and produce rotation, the contact surface conversion always of centralizer and well casing inwall.The utlity model has simple in structurely, quick for installation, can effectively prevent eccentric wear, prolong the life cycle of centralizer, improve the advantage of oilfield economic benefit.
Description of drawings: Fig. 1 is the curved surface of the semicircle axle sleeve 1 of the utility model and the structural representation of rotor 3, Fig. 2 is the structural representation of the specific embodiment two, Fig. 3 is the A-A sectional view of Fig. 2, and Fig. 4 is the structural representation of circlip 2, and Fig. 5 is an application state schematic diagram of the present utility model.
The specific embodiment one: present embodiment is made up of two semicircle axle sleeves 1 and two elastic springs 2, be fixed with rotor 3 on the curved surface of each semicircle axle sleeve 1, the two ends up and down of semicircle axle sleeve 1 curved surface have circlip groove 4, the plane of two semicircle axle sleeves 1 is relative, and two elastic rings 2 are fixed in the circlip groove 4 of two semicircle axle sleeves 1.Rotor 3 is 10 °～60 ° with the inclination angle of semicircle axle sleeve 1 axis; Rotor 3 is 26 ° with the inclination angle of semicircle axle sleeve 1 axis.
The specific embodiment two: the difference of the present embodiment and the specific embodiment one is, is provided with two inserted links 5 and two jacks 6 on the plane of each semicircle axle sleeve 1.Two inserted links 5 and two jack 6 diagonal angle settings.Other composition is identical with the specific embodiment one with annexation.On the plane of semicircle axle sleeve 1, be provided with two inserted links 5 and two jacks 6,, prevent from together two semicircle axle sleeves 1 are shifted mutually, influence result of use in order that in use.
When the utility model is manufactured in processing, only need open a mould, reduced the cost of product, because the structure of each semicircle axle sleeve 1 all is identical, two inserted links 5 and two jack 6 inserted links 5 or jack 6 are all in the same side or the diagonal angle setting, bringing two arbitrarily can be mutually to being buckled together, install convenient and swift especially, saving of work and time.
