Abstract
A kind of self-regulated polarisation bar, comprise tuningout bar, housing, tuningout seat, tuningout ball, hanging head, back of the body cap and polished rod, it is characterized in that: housing is set to rectangle or cylindrical, upper top is provided with the centre bore that is greater than polished rod diameter, the all sides of centre bore are provided with lubricant reservoir, bottom is provided with a hanging head be threaded with housing, housing pushes up bottom surface and is provided with tuningout seat with deep-slotted chip breaker and end face band spin groove or smooth flat in the middle part of a bottom surface, tuningout ball is connected with housing by tuningout seat with tuningout bar, and polished rod is connected with hanging head by back of the body cap.The utility model eliminates the operation of oil pumper tuningout and the equipment of well head offset and operation, extends the application life of packing, reduces the labour intensity of workman, improve the production time efficiency of oil well.
Description
Technical field
The utility model relates to a kind of polished rod from the method for tuningout and self-regulated polarisation bar, solves polished rod eccentric wear packing and causes well head leakage of oil to affect to produce and the problem of contaminated environment.
Background technology
The leakage of oil of the oil pumping well head more than 90% in oil field, the measure solving at present well head leakage of oil is all make an effort on wellhead sealing device, for this reason investigation and application well head deflection-regulating sealer miscellaneous.Serve good control action to the leakage of oil of solution well head, but add the wearing and tearing of silver hardware, change hardware also more difficult than changing packing, economic loss is also large.Fundamentally really do not solve the problem of well head leakage of oil.The main cause of well head leakage of oil is caused to be the load suspension point of horse head, light is done with well head center not on a center line, because polished rod is a straight-bar, polished rod becomes indeformable, eccentric wear is packing or not, depend on polished rod whether linear running in pumping, in the ordinary course of things, well head is not inclined, mainly installing oil pumper is not just causing beam rating suspension point to depart from well head center line, accomplish that beam rating suspension point does not depart from well head center line and is difficult to, because beam pumping unit head is very large, mounting and adjusting is very difficult, several centimeters of movements all around can only be accomplished, several millimeters of movements are not accomplished at all, load suspension point and well head differ from one millimeter and make it beam rating suspension point and depart from several centimeters, well head, be also be difficult to beam rating suspension point and well head center to adjust on a center line with ceiling hammer.Inclined head it off is finely tuned by polished rod when pumping unit horsehead load suspension point is difficult to adjustment and uncomfortable well head.
Summary of the invention
The purpose of this utility model is to provide a kind of self-regulated polarisation bar, overcomes the defect that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises tuningout bar, housing, tuningout seat, tuningout ball, hanging head, back of the body cap and polished rod, it is characterized in that: housing is set to rectangle or cylindrical, upper top is provided with the centre bore that is greater than polished rod diameter, the all sides of centre bore are provided with lubricant reservoir, bottom is provided with a hanging head be threaded with housing, housing pushes up bottom surface and is provided with tuningout seat with deep-slotted chip breaker and end face band spin groove or smooth flat in the middle part of a bottom surface, tuningout ball is connected with housing by tuningout seat with tuningout bar, and polished rod is connected with hanging head by back of the body cap.
The lubricant reservoir of case top, top is provided with oil filler point, and bottom is equipped with micron-sized oil outlet.
The cambered surface of tuningout ball and tuningout seat matches, and tuningout ball is threaded with tuningout bar or welds.
Polished rod upper and lower is provided with male thread, and appearance scribbles one deck abrasion-proof corrosion-proof layer.
Compared with the prior art the utility model has the following advantages:
1, solve the beam rating suspension point problem concentric with well head by self-regulated polarisation bar, not be used in well head and complicated well head deflection-regulating sealer tuningout well head and polished rod are installed.
2, polished rod is simple from device for adjusting deviation structure, easy to maintenance, lays down load just can keep in repair as long as polished rod is put into bottom dead centre, pollution-free without crude oil.
3, eliminate the operation of oil pumper tuningout and the equipment of well head offset and operation, extend the application life of packing, reduce the labour intensity of workman, improve the production time efficiency of oil well.

Detailed description of the invention
For disclosing the technical solution of the utility model further, elaborated by embodiment below in conjunction with Figure of description:
The utility model comprises tuningout bar 1, housing 3, tuningout seat 2, spin 7, tuningout ball 8, hanging head 4, back of the body cap 5 and polished rod 6, it is characterized in that: housing is set to rectangle or cylindrical, upper top is provided with the centre bore that is greater than polished rod diameter, the all sides of centre bore are provided with lubricant reservoir, bottom is provided with a hanging head be threaded with housing, housing pushes up bottom surface and is provided with tuningout seat with deep-slotted chip breaker and end face band spin groove or smooth flat in the middle part of a bottom surface, tuningout ball is connected with housing by tuningout seat with tuningout bar, and polished rod is connected with hanging head by back of the body cap.
When applying the utility model, polished rod eye is connected with beam rating hitch point by hair plait, adjusts the length that burr debate son, makes two hairs debate sub-length equal and fixing.Be connected with polished rod eye by tuningout bar by square clamp, polished rod is connected with the sucker rod in well again, and start oil pumper, regulate the elasticity of packing, oil pumper and self-regulated polarisation bar enter normal work.When polished rod is up from bottom dead centre, if beam rating suspension point is partial to the left side of well head center line, tuningout bar moves to left, make tuningout bar and beam rating suspension point point-blank, polished rod is motionless, keep and well head central vertical, at polished rod under the effect of device for adjusting deviation, realize tuningout bar and polished rod rectilinear motion up or down separately.Reach the object of polished rod not eccentric wear well head packing, extend the application life of well head packing, reduce the number of times changing packing, improve the production time efficiency of oil well.
