Abstract
The utility model provides a righting abrasion-proof sucker-rod coupling. An abrasion-resistant non-metal body is arranged on the metal outer surface at one end of the sucker-rod coupling; internal threads used for connecting a pumping rod are formed through the sucker-rod coupling; an over-current channel is formed on the abrasion-resistant non-metal body; a plane surface is arranged on the sucker-rod coupling at the cylindrical section not being covered by the abrasion-resistant non-metal body; and a pipe wrench is mounted on the plane surface. When the over-current channel is designed on the abrasion-resistant non-metal body, the external diameter of the abrasion resistant non-metal body can be enlarged, so that the sucker-rod coupling is provided with the function of righting the sucker rod, the sucker rod can be provided from bending, and the friction between the sucker rod and the oil pipe is reduced; and as the abrasion-resistant non-metal body prevents metal of the sucker-rod coupling from contacting the oil pipe, abrasion is avoided, thereby prolonging the work cycle of the oil well, and improving economic benefit.
Description
One, technical field
The utility model belongs to the rod collar of oil field oil pumping usefulness, is a kind of righting anti-abrasion rod collar.
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 abrasion-proof sucker rod box cupling to solve oil pipe and sucker rod partial wear on the oil recovery technique, as Chinese patent application 200420029609.3 abrasion-proof sucker rod box cuplings, this rod collar is in order to prevent throttling, external diameter can not be excessive, so there is not centralizing function, can not prevent that sucker rod is crooked in oil pipe, the problem of sucker rod partial wear oil pipe still occur, the oil well production cycle is still shorter.
Three, summary of the invention
The purpose of this utility model is a kind of righting anti-abrasion rod collar of design, makes box cupling have the righting anti-abrasion effect, prolongs the application life of sucker rod, reduces oil well operation number of times.
The purpose of this utility model is achieved in that on rod collar one end outer metallic surface wear-resisting non-metallic body is set, the internal thread that the logical connection sucker rod of wearing is arranged in the rod collar, the overcurrent groove is arranged on wear-resisting non-metallic body, and the cylindrical section that is not coated by wear-resisting non-metallic body at rod collar is provided with the plane that pipe wrench is installed.
The overcurrent groove is spirality or is straight shape.
The beneficial effects of the utility model are: the overcurrent groove is arranged on wear-resisting non-metallic body, the external diameter of wear-resisting non-metallic body can increase, thereby has an effect of setting upright sucker rod, can prevent rod sag, reduce the friction between sucker rod and the oil pipe,, avoid wearing and tearing because wear-resisting non-metallic body has prevented that the metal of rod collar from contacting with oil pipe, thereby can prolong the oil well work period, increase economic efficiency.
Four, description of drawings
Accompanying drawing is an assembling drawing of the present utility model.
Five, the specific embodiment
Embodiment of the present utility model describes below in conjunction with accompanying drawing.
On rod collar 1 one end outer metallic surface, wear-resisting non-metallic body 2 is set, wear-resisting non-metallic body 2 is by on the fixing rod collar 1 of hot tapping technique, on the contact surface of wear-resisting non-metallic body 2 and rod collar 1, groove can be set, make wear-resisting non-metallic body 2 better be fixed into one with rod collar 1.The internal thread 3 of the logical connection sucker rod of wearing is arranged in the rod collar 1, on wear-resisting non-metallic body 2 overcurrent groove 5 is arranged, the cylindrical section that is not coated by wear-resisting non-metallic body 2 on rod collar 1 is provided with the plane 4 that pipe wrench is installed.Overcurrent groove 5 is a spirality or for straight shape, and overcurrent groove 5 is beneficial to the setting upright of sucker rod for spirality, but difficulty of processing is big, and overcurrent groove 5 is that straight shape is easy to process, but sets upright weak effect, can be according to oil well situation choose reasonable.After on the wear-resisting non-metallic body 2 overcurrent groove 5 being arranged, the external diameter of wear-resisting non-metallic body can increase, as being the utility model that uses in ￠ 62 oil pipes at internal diameter, the external diameter of wear-resisting non-metallic body can increase to ￠ 54-￠ 59, oil stream passes through for 5 li from the overcurrent groove, the external diameter of wear-resisting non-metallic body approaches pipe aperture, sucker rod is in sets upright the state operation, can prevent rod sag.
Claims (2)
1, a kind of righting anti-abrasion rod collar, on rod collar (1) one end outer metallic surface, wear-resisting non-metallic body (2) is set, the internal thread (3) that the logical connection sucker rod of wearing is arranged in the rod collar (1), it is characterized in that: overcurrent groove (5) is arranged on wear-resisting non-metallic body (2), and the cylindrical section that is not coated by wear-resisting non-metallic body (2) at rod collar (1) is provided with the plane (4) that pipe wrench is installed.
2, righting anti-abrasion rod collar according to claim 1 is characterized in that: overcurrent groove (5) is spirality or is straight shape.
