Abstract

The utility model provides a sucker rod rotary apparatus, including the polished rod checkpost, the polished rod eye, the polished rod, the polished rod sealing ware, oil pipe, the sucker rod, the sleeve pipe, it is intraductal that oil pipe goes into the cover down, installation polished rod sealing ware behind set outside of tubes is stretched out on oil pipe's upper portion, the polished rod passes the polished rod sealing ware and is connected with the sucker rod, the sub -unit connection oil -well pump piston of sucker rod, after being blocked by the polished rod checkpost, the upper portion of polished rod hangs on the polished rod eye, the generator is twistd reverse in the installation on the sucker rod, the revolving force that twists reverse the generator production when liquid stream impulsion and sucker rod switching -over motion transmits for the sucker rod, install the fairing between polished rod checkpost and polished rod eye, the sucker rod can rotate by oneself, let the whole circumference of sucker rod all attend with oil pipe's contact, make abrasion part dispersion to whole sucker rods surface, avoid the sucker rod to appear grinding partially, can improve the life of sucker rod, avoid grinding partially and make sucker rod damage back the oil well operation that the fracture caused appear, can reduce the operating cost, increase the oil well production time, the crude oil yield is increased.

Description

Sucker rod rotary apparatus
technical field:
The utility model belongs to the mechanical device of oil pumping in oil fields, is a kind of sucker rod rotary apparatus.
background technology:
In oil pumping in oil fields system, R a T has relative contact movement, certainly exists to rub between sucker rod and oil pipe, has also just inevitably occurred the wearing and tearing of sucker rod.Existing R a T is constant at friction position circumferentially, causes sucker rod to be worn circumferentially only having the position of a side, is called eccentric wear at the scene.In order to reduce the wearing and tearing of sucker rod, oil field has filled centralizer on rod string, makes sucker rod be in middle position, but oil pumping rod centering device also there will be the problem only having the position of a side to be worn, i.e. centralizer eccentric wear, centralizer is because of after eccentric wear damage, and do not have centralizing function to sucker rod, sucker rod also can be damaged by eccentric wear, there is rod broken accident, oil well with short production cycle, causes workover rig service to oil well, increases oil well Meteorological.
summary of the invention:
The purpose of this utility model is a kind of sucker rod rotary apparatus of design, sucker rod can be rotated when pumping, sucker rod flank wear is distributed to whole circumference and all participates in wearing and tearing, avoid sucker rod partial wear, extend the application life of sucker rod, extend the oil well production cycle, reduce oil well operation number of times.
The purpose of this utility model is achieved in that and comprises optical-rod clamp, polished rod eye, polished rod, polished rod sealer, oil pipe, sucker rod, sleeve pipe, enter under oil pipe in sleeve pipe, the top of oil pipe is stretched out sleeve pipe and is installed polished rod sealer afterwards outward, polished rod is connected with sucker rod through polished rod sealer, the bottom of sucker rod connects oil pump piston, rear-mounted is blocked on polished rod eye by optical-rod clamp in the top of polished rod, sucker rod installs torsion generator, the revolving force that torsion generator produces when the impulsion of liquid stream and sucker rod commutation motion passes to sucker rod, between optical-rod clamp and polished rod eye, damping device is installed.
The beneficial effects of the utility model are: on sucker rod, install torsion generator, the revolving force that torsion generator produces when the impulsion of liquid stream and sucker rod commutation motion passes to sucker rod, sucker rod can be rotated voluntarily, the whole circumference of sucker rod is allowed all to participate in the contact with oil pipe, abrading section is made to be distributed to whole sucker rod surface, sucker rod is avoided to occur eccentric wear, the application life of sucker rod can be improved, the oil well operation caused that ruptures is there is after avoiding eccentric wear that sucker rod is damaged, operating cost can be reduced, increase the oil well production time, increase crude output.
accompanying drawing illustrates:
Accompanying drawing 1 is schematic diagram of the present utility model.
detailed description of the invention:
Below in conjunction with accompanying drawing 1, embodiment of the present utility model is described.
As seen from the figure, embodiment of the present utility model comprises optical-rod clamp 1, damping device 2, polished rod eye 3, polished rod 4, polished rod sealer 5, oil pipe 6, sucker rod 7, sleeve pipe 8, torsion generator 9, oil pipe enters for 6 times in sleeve pipe 8, the outer rear installation polished rod sealer 5 of sleeve pipe 8 is stretched out on the top of oil pipe 6, polished rod 4 is connected with sucker rod 7 through polished rod sealer 5, the bottom of sucker rod 7 connects oil pump piston, the top of polished rod 4 is blocked by optical-rod clamp 1, damping device 2 is installed between optical-rod clamp 1 and polished rod eye 3, the friction between optical-rod clamp 1 and polished rod eye 3 is made to become rolling friction, be conducive to sucker rod 7 to rotate, fluid column on the weight of sucker rod 7 connected under polished rod 4 and oil pump piston is suspended on polished rod eye 3, sucker rod 7 is installed torsion generator 9, the revolving force that torsion generator 9 produces when the impulsion of liquid stream and sucker rod 7 commutate motion passes to sucker rod 7, it is made to drive sucker rod 7 to rotate.Damping device 2 is installed between optical-rod clamp 1 and polished rod eye 3, makes the friction between optical-rod clamp 1 and polished rod eye 3 become rolling friction, be conducive to sucker rod 7 and rotate.The top of polished rod eye 3 is connected on oil pumper.
The installation quantity of torsion generator 9 is determined by the situation of well, can install one on every root sucker rod, also can install at interval, also can concentrate on one section of installation, also can be dispersed on whole roofbolt and install.
Torsion generator 9 is generally spinning centralizer.
