Abstract
The utility model discloses a corrosion prevention sucker rod abrasion resistance pair which comprises a sucker rod joint, an abrasion block, a screw nut, a sucker rod body and a slide sleeve, wherein the upper end of the sucker rod body is orderly connected with the screw nut and the sucker rod joint; the abrasion block is arranged on the sucker rod joint; and the slide sleeve is arranged on the sucker rod body. The utility model has the characteristics of advanced upright method, good upright effect, high reliability, convenient installation, corrosion prevention, abrasion resistance, long service life, prolonged quality assuring period of pumping wells and the like, and can be widely used in the oil pumping system with sucker rods for oil production wells.
Description
One, technical field
The utility model relates to the oil well sucker rod, the wear-resistant pair of particularly a kind of anti-corrosion pumping bar.
Two, background technology
In oil exploitation well sucker-rod pumping system, exist inevitable wearing and tearing, particularly deep-well and inclined shaft between hollow rod and the oil pipe, sucker rod is easy to bending in oil pipe, the problem that serious sucker rod wearing and tearing oil pipe occurs, after producing wearing and tearing oil pipe and sucker rod can not be used, cause the oil well operation, oil well repair free period is short, increase operating cost, increase rod tube consumption, the oil well off-time is many, has reduced crude output.Existing rod collar is common box cupling, and its shortcoming is that it is bigger than sucker rod diameter, easier wearing and tearing oil pipe; The centralizer body material is selected nonmetals mostly for use, material softer, though the oil pipe that can not wear and tear has played temporary transient protective effect, because its nonmetals buffing damage is very fast, guard time is short; Heavy wear still appears in oil pipe, sucker rod.Disconnected take off phenomenon and happen occasionally, directly influence the normal operation of pumpingh well.
Three, summary of the invention
The purpose of this utility model provides a kind of not only long service life, anticorrosion, wear-resisting but also effectively overcome shortcoming or the not enough wear-resistant pair of anti-corrosion pumping bar of avoiding above-mentioned prior art to exist.
The wear-resistant pair of anti-corrosion pumping bar described in the utility model comprises rod collar, abrading block, nut, the oil pumping body of rod and sliding sleeve.Described oil pumping body of rod upper end is connected with rod collar in turn with nut, and abrading block is installed on the rod collar, on the oil pumping body of rod sliding sleeve is installed.
Wherein, be covered with a tungsten coat of metal on the described sucker rod.Described sliding sleeve is movably installed on the oil pumping body of rod, can with the oil pumping body of rod move up and down and up and down or rotational slide.Described abrading block and sliding sleeve are to select in the macromolecule corrosion-proof wear-resistant material.
The utility model has following advantage compared with prior art:
1, the wear-resistant duplicate invoice of anti-corrosion pumping bar is connected on bending, the inclination position of rod string, during oil pumping, sets upright the mode advanced person, set upright effective, the reliability height, easy for installation;
2, plating tungsten metal sucker rod itself has anticorrosion, abrasion resistance, can avoid sucker rod sucker rod, oil pipe wear problems to occur in the bending of oil pipe internal cause, inclination;
3, long service life prolongs being excused from a college course the phase of pumpingh well.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Five, the specific embodiment
The wear-resistant pair of anti-corrosion pumping bar comprises rod collar 1, abrading block 5, nut 2, the oil pumping body of rod 3 and sliding sleeve 4, and the oil pumping body of rod 3 upper ends are connected with rod collar 1 in turn with nut 2, and abrading block 5 is installed on the rod collar 1, on the oil pumping body of rod 3 sliding sleeve 4 are installed.
Be covered with a tungsten coat of metal on the oil pumping body of rod 3.Sliding sleeve 4 is movably installed on the oil pumping body of rod 3, can with the oil pumping body of rod 3 move up and down and up and down or rotational slide.Abrading block 5 and sliding sleeve 4 are to select among macromolecule corrosion-proof wear-resistant material PEEK, the PAI.
Claims (4)
1, the wear-resistant pair of a kind of anti-corrosion pumping bar, comprise rod collar, abrading block, nut, the oil pumping body of rod and sliding sleeve, it is characterized in that described oil pumping body of rod upper end is connected with rod collar in turn with nut, abrading block is installed on the rod collar, on the oil pumping body of rod sliding sleeve is installed.
2, the wear-resistant pair of anti-corrosion pumping bar according to claim 1 is characterized in that being covered with on the described sucker rod tungsten coat of metal.
3, the wear-resistant pair of anti-corrosion pumping bar according to claim 1 is characterized in that described sliding sleeve is movably installed on the oil pumping body of rod, can with the oil pumping body of rod move up and down and up and down or rotational slide.
4, the wear-resistant pair of anti-corrosion pumping bar according to claim 1 is characterized in that described abrading block and sliding sleeve are to select in the macromolecule corrosion-proof wear-resistant material.
