Abstract
The invention relates to a rotary groove type eccentric-wear-resisting device for a pumping well. When a sucker rod eccentric-wear-resisting device is used on site, the eccentric-wear-resisting effect is not remarkable, so that a sucker rod and an oil pipe are damaged and disengaged. The rotary groove type eccentric-wear-resisting device for the pumping well is provided with a central rod. The central rod is sleeved with a cylindrical anti-wear body. Multiple spiral grooves are evenly formed in the outer wall of the anti-wear body from top to bottom. An upper limiting ring and a lower limiting ring are fixed to the central rod and located on the upper side and the lower side of the anti-wear body respectively. Gaps exist between the upper limiting ring and the anti-wear body and between the lower limiting ring and the anti-wear body respectively. The rotary groove type eccentric-wear-resisting device for the pumping well is long in anti-wear valid period, prevents the situation that the sucker rod and the oil pipe directly make contact with each other and are abraded, prolongs the service lives of the sucker rod and the oil pipe, and maintains the normal production of the pumping well.
Description
Technical field
the present invention relates to the equipment preventing R a T generation eccentric wear in a kind of petroleum recovery operations, be specifically related to a kind of rotation grooved preventing offset wear pumping well device.
Background technology
Along with oil field development enters the middle and later periods, the phenomenon of R a T generation eccentric wear will grow in intensity, and have a strong impact on field produces.Although existing bias-wearing-proof apparatus of pumping rod kind is more, at the scene in use procedure, eccentric abrasion prevention DeGrain, still there is the problem of local heavy wear, cause the damage of sucker rod, oil pipe, breaking takes off, directly affect the normal production of pumpingh well, cause oil well operation maintenance cost to increase.
Summary of the invention
The object of this invention is to provide the rotation grooved preventing offset wear pumping well device that a kind of structure simply, effectively prevents sucker rod partial wear.
The technical solution adopted in the present invention is:
Rotate grooved preventing offset wear pumping well device, it is characterized in that:
Be provided with center-pole, on center-pole, cover has tubular anti-abrasion body, and anti-abrasion body outer wall is evenly provided with spiral multiple tracks groove from top to bottom.
On center-pole, the upper and lower both sides of anti-abrasion body are respectively arranged with and are fixed on upper limit ring on center-pole and lower limit ring, upper limit ring and all there is gap between lower limit ring and anti-abrasion body.
The present invention has the following advantages:
Structure of the present invention is simple, and the wear-resistant time is long, avoids sucker rod, oil pipe directly contacts and produce wearing and tearing, extend the application life of R a T, keep oil well normally to produce, extend oil well repair free period, save oil well operation maintenance cost, increase crude output.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.
In figure, 1-upper limit ring, 2-anti-abrasion body, 3-center-pole, 4-lower limit ring.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be described in detail.
The one that the present invention relates to rotates grooved preventing offset wear pumping well device, is provided with center-pole 3, and on center-pole 3, cover has tubular anti-abrasion body 2, and anti-abrasion body 2 outer wall is evenly provided with spiral multiple tracks groove from top to bottom.On center-pole 3, the upper and lower both sides of anti-abrasion body 2 are respectively arranged with and are fixed on upper limit ring 1 on center-pole 3 and lower limit ring 4, upper limit ring 1 and all there is gap between lower limit ring 4 and anti-abrasion body 2.
Owing to being provided with spiral multiple tracks groove from top to bottom on anti-abrasion body 2, fluid applies the power of circumferencial direction up and down to anti-abrasion body 2 through out-of-date meeting, make anti-abrasion body 2 rotate around center-pole 3, when sucker rod runs into eccentric wear, realizes the uniform wear of anti-abrasion body 2.According to length and the eccentric wear situation of sucker rod, quantity and the spacing distance of eccentric abrasion prevention device can be adjusted flexibly.
Content of the present invention is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading manual of the present invention to any equivalence that technical solution of the present invention is taked, is claim of the present invention and contains.
