Abstract
The utility model relates to a pumping rod straightening device which comprises a straightening rod and a straightening sleeve, wherein upper pumping rod threads are arranged at the upper part of the straightening rod, lower pumping rod threads are arranged at the lower part of the straightening rod, a small diameter section is arranged at the middle part of the straightening rod, and the straightening sleeve is casted at the small diameter section at the middle part of the straightening rod, is provided with an oil passing groove and is made of a reinforcing nylon material. With the adoption of the pumping rod straightening device, a pumping rod can be straightened, and the bending degree is decreased when the pumping rod descends, therefore abrasion can be lightened, the service life of an oil pipe and the pumping rod can be prolonged, and the production period of an oil well can be prolonged; and the straightening sleeve is casted on the straightening rod and can not be move relatively to the straightening rod, therefore the service life of the straightening sleeve can be prolonged.
Description
One, technical field:
The utility model is the interior equipment of well that oil field pumping well is used, particularly a kind of oil pumping rod centering device.
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, the problem of sucker rod partial wear oil pipe occurring, behind the generation eccentric wear oil pipe and sucker rod can not used, cause the oil well operation, oil well repair free period is short, increases operating cost, increases rod tube consumption, the oil well off-time is many, reduces crude output.The normal problem that adopts oil pumping rod centering device to solve oil pipe and sucker rod partial wear on the oil recovery technique.
Three, summary of the invention:
The purpose of this utility model provides a kind of oil pumping rod centering device, alleviates line bend under the sucker rod, improves oil pipe, sucker rod application life, prolongs the oil well production cycle.
The utility model is achieved in that by righting rod, supporting positive cover to be formed, last sucker rod screw thread is arranged at righting rod top, the lower sucker rod screw thread is arranged at the righting rod bottom, there is reduced diameter section at the righting rod middle part, supporting positive cover is gone up in the reduced diameter section place casting of righting rod middle part, helicla flute is arranged on the supporting positive cover, and supporting positive cover is made by strengthening nylon material.
The beneficial effects of the utility model are: can set upright sucker rod, degree of crook alleviated when sucker rod was descending, can alleviate wearing and tearing, improve oil pipe, sucker rod application life, can prolong the oil well production cycle, supporting positive cover casting is on righting rod, and supporting positive cover and righting rod can not relative motions, the application life that can improve supporting positive cover.
Four, description of drawings:
Accompanying drawing 1 is the assembling drawing of the utility model embodiment.
Five, the specific embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Be made up of righting rod 1, supporting positive cover 2, last sucker rod screw thread 3 is arranged at righting rod 1 top, and lower sucker rod screw thread 4 is arranged at righting rod 1 bottom, there is reduced diameter section at righting rod 1 middle part, supporting positive cover 2 is gone up in the casting of reduced diameter section place, righting rod 1 middle part, and helicla flute 5 is arranged on the supporting positive cover 2, and supporting positive cover 2 is made by strengthening nylon material.The utility model is installed between the rod string, is distributed in the oil pipe section of wearing and tearing easily, and sucker rod is played centralizing function, can be not crooked when sucker rod is descending.
