Abstract
The utility model relates to an eccentric wear resistant sucker rod which is composed of a centering guide, a sucker rod and a wear resistant pipe; wherein, the wear resistant pipe is positioned through a casting way in the main body of the sucker rod; the centering guide has an inner thread connected with the thread of the sucker rod; and the sucker rod has metric threads exposed at two ends. The surface of the sucker rod is cast with the wear resistant pipe which is made of a hard wearing material, the sucker rod has an eccentric wear resistant performance and has end provided with the centering guide which may realize a centering towards the end of the sucker rod. Box coupling provided at the two ends of the sucker rod can go against eccentric wear and further enhance the service life of the sucker rod, prolong the production cycles of oil wells, reduce the maintenances made to the oil wells and ultimately enhance the economic benefits of the oil wells.
Description
One, technical field
The utility model belongs to the mechanical device of using in the oil field pumping well, particularly a kind of eccentric wear prevention pumping rod.
Two, background technology
In the oil pumping system of oil field, R a T has relative contact movement, certainly existing between sucker rod and the oil pipe and rubbing, and the wearing and tearing of sucker rod, oil pipe also just inevitably occurred.Particularly deep-well and inclined shaft, sucker rod is easy to bending in oil pipe, the problem that serious sucker rod partial wear oil pipe occurs, after producing eccentric wear 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, reduces crude output.The normal problem that adopts the eccentric wear sucker rod to solve oil pipe and sucker rod partial wear on the oil recovery technique.As the patent No.: 03271902.7 oil pipe, the anti-eccentric wear pair of sucker rod, it is exactly a kind of eccentric wear sucker rod, but this eccentric wear sucker rod wearing bush length is shorter, do not have the effect of anti-eccentric wear, cause the application life of rod string short, the frequent problem of workover rig service to oil well is not resolved, and the pumpingh well economic benefit is low.
Three, summary of the invention
The purpose of this utility model is a kind of eccentric wear prevention pumping rod of design, makes its sucker rod body of rod also can prevent eccentric wear, and the box cupling at eccentric wear prevention pumping rod two ends can be prevented eccentric wear, improves the application life of rod string.
The purpose of this utility model is achieved in that by sucker rod, abrasionproof pipe to be formed, and abrasionproof Guan Zhu is contained on the body of rod of sucker rod, and the abrasionproof length of tube is greater than 1000mm.The interior external threading of centralizer and the thread connection of sucker rod, male thread is exposed at the sucker rod two ends.
The beneficial effects of the utility model are: the sucker rod external surface is cast with the abrasionproof pipe, the sucker rod body of rod can be prevented eccentric wear, there is centralizer the sucker rod end, can set upright the end of sucker rod, the box cupling at sucker rod two ends can be prevented eccentric wear, in the application life that can improve rod string, prolongs the oil well production cycle, reduce workover rig service to oil well, improve the economic benefit of pumpingh well.
Four, description of drawings
Accompanying drawing is an assembling drawing of the present utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Embodiment of the present utility model is made up of sucker rod 2, abrasionproof pipe 3, and 3 castings of abrasionproof pipe are contained on the body of rod of sucker rod 2, and abrasionproof pipe 3 length are greater than 1000mm.The interior external threading of centralizer 1 and the thread connection of sucker rod 2, male thread is exposed at sucker rod 2 two ends.Abrasionproof pipe 3 is a high-abrasive material, and the body of rod of sucker rod 2 can be prevented eccentric wear, and the end of 1 pair of sucker rod 2 of centralizer is set upright, and the box cupling at sucker rod 2 two ends can be prevented eccentric wear, the long service life of rod string, and the oil well production cycle is long, and workover treatment is few, the economic benefit height.
