Abstract
The utility model relates to an anti-eccentric wearing pumping rod and comprises a centralizer, a pumping rod and a wear pipe, wherein the wear pipe is casted on the rod body of the pumping rod, the inner female thread of the centralizer is connected with the screw thread of the pumping rod, both ends of the pumping rod expose male threads. The external surface of the pumping rod is casted with the wear pipe made of abrasion resistance materials, the rod body of the pumping rod can prevent from eccentric wearing, the end portion of the pumping rod is provided with the centralizer that can centralize the end portion of the pumping rod, couplings on both ends of the pumping rod can prevent from eccentric wearing, extending the life duration of the pumping rod and the production cycle of oil wells, reducing workover treatment of oil wells, and increasing the economic benefits of pumping 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 the box cupling at its eccentric wear prevention pumping rod two ends can prevent eccentric wear, and the sucker rod body of rod also can be prevented eccentric wear, improves the application life of rod string.
The purpose of this utility model is achieved in that by centralizer, sucker rod, abrasionproof pipe to be formed, and abrasionproof Guan Zhu is contained on the body of rod of sucker rod, the interior external threading of centralizer and the thread connection of sucker rod, and 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 Ji 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 by being made up of centralizer 1, sucker rod 2, abrasionproof pipe 3, and 3 castings of abrasionproof pipe are contained on the body of rod of sucker rod 2, the interior external threading of centralizer 1 and the thread connection of sucker rod 2, and male thread is exposed at sucker rod 2 two ends.Sucker rod 2 external surfaces are cast with abrasionproof pipe 3, and abrasionproof pipe 3 is a high-abrasive material, and the body of rod of sucker rod 2 can be prevented eccentric wear, and centralizer 1 is a rotary type centralizer long service life.The end of 1 pair of anti-sucker rod 2 of centralizer is set upright, and the box cupling at sucker rod 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 Ji high efficiency.
Claims (2)
1, a kind of eccentric wear prevention pumping rod, form by centralizer (1), sucker rod (2), it is characterized in that: abrasionproof pipe (3) casting is contained on the body of rod of sucker rod (2), the thread connection of the interior external threading of centralizer (1) and sucker rod (2), and male thread is exposed at sucker rod (2) two ends.
