Abstract
The invention discloses a kind of method for preventing oil pumper from thering is polished rod oil well to be missed with packing, by iron wire spiral wound on the non-type polished rod coordinated with packing, and iron wire two ends are fixed on base；With moving up and down for nonstandard polished rod, iron wire polishing polished rod surface；On the hole nest that cement is attached to the nonstandard position of polished rod such as corrosion, more than 24h is solidified, during which polished rod does not rest, then repeatedly.The present invention need not solve the problems, such as the leakage of polished rod and packing to change polished rod or packing for a long time by stopping well, but complete control during oil well normal production operation, extend the service life of polished rod and packing, prior art operation difficulty, workload and economic loss are significantly reduced, oil well steadily, is efficiently produced.
Description
Technical field
It is more particularly to a kind of to prevent pumping unit oil well normally production is missed with packing the invention belongs to oil well production field
Method.
Background technology
Oil pumper is a kind of machinery equipment for exploiting oil, is commonly called as " machine of kowtowing ", oil is gone out by the method for oil well pump
Well.When oil pumper upstroke, oil pipe elastic shrinkage is moved upwards, and driving mechanical block-relief oil production device is moved upwards, hits sliding sleeve
Produce vibration；Meanwhile, copper current only valve is closed, and reducing piston assembly closure oil is when oil pumper down stroke, oil pipe elastic elongation
Move downward, driving mechanical block-relief oil production device is moved downward, hit sliding sleeve and produce vibration；Meanwhile, reversed check valve part is closed,
Reducing piston assembly still blocks oil jacket ring shaped oil passage, makes reversed check valve lower zone formation higher-pressure region, and this motion is again right
Oil flow channel in stratum produces a kind of reverse impulsive force.Common oil pumper is that beam pumping unit is that oil field is wide variety of
Traditional pumping unit, is generally directly dragged by ordinary ac asynchronous motor.
Although last 100 yearses have been developed in oil pumper, still packing leakage problem is present.Because polished rod is Steel material, use
Time is longer easily by crude oil rain erosion, and packing is then worn due to the irregular of polished rod, packing abrasion occurs, polished rod
There is corrosion mouth, cause leakage.The leakage of polished rod and packing can usually cause well head greasy dirt, and pollution is brought to surrounding environment.It is existing
It is many using stopping oil mining in technology, the method by changing polished rod or packing, to solve to miss problem.But, change light
Bar or packing workload are big, difficulty is high, cost is also higher；In addition, when oil well is normally produced, stopping well totally unfavorable to oil well.
Oil well stops the normal operation that production also has a strong impact on oil well, or even therefore can cause lie well, upper operation, then influences crude oil
Yield, very big economic loss is caused to exploitation person, solves the problems, such as that leakage will lose because stopping oil well operation according to every mouthful of well of valuation
About 100,000 yuans.Therefore, develop one kind do not influence oil well normal operation, do not stop under oil well conditions administer polished rod hole nest,
The method of packing leakage has its realistic meaning.
The content of the invention
For drawbacks described above, it is an object of the invention to provide a kind of side for preventing oil pumper from having polished rod oil well to be missed with packing
Method, does not influence to administer packing, polished rod leakage problem in the case of oil well output, extends the service life of polished rod and packing to realize,
Oil well is set steadily, efficiently to produce.
A kind of method for preventing oil pumper from having polished rod oil well to be missed with packing, is comprised the following steps：
(1) by iron wire spiral wound on the polished rod of the nonstandard leakage coordinated with packing, and iron wire two ends are fixed
On base；
(2) moving up and down with nonstandard polished rod, iron wire polishing polished rod surface；
(3) cement is attached to the irregular position of nonstandard polished rod as cheated on nest, solidifies more than 24h, during which polished rod is not
Rest production；
(4) then repeat step (3) 3-7 times, you can realize that packing is not missed.
It is preferred that, iron wire described in step (1) is more than No. 5 model iron wires, and the spacing of helical form iron wire is 0.3-8cm,
Iron wire length is 1-3m.
It is preferred that, the spacing of the helical form iron wire is 0.5-5cm, and iron wire length is 1.5m.
It is preferred that, the time on the polishing polished rod of iron wire described in step (2) surface is 1-3 days.
It is preferred that, the time on the polishing polished rod of iron wire described in step (2) surface is 1.5 days.
It is preferred that, setting time is 30-48h in step (3).
It is preferred that, setting time is 45h in step (3).
It is preferred that, repeat step (3) 4-6 times in step (4).
It is preferred that, repeat step (3) number of times is 5 times.
Compared with prior art, its advantage is the present invention：
A kind of method for preventing oil pumper from thering is polished rod oil well to be missed with packing of the present invention, for the hole nest of bare rod corrosion
Filled up with cement, polished rod surface is handled with iron wire, this two all serve the round and smooth degree effect for ensureing polished rod；Meanwhile, work as water
Mud on polished rod with rubber packing inner faces contact when, packing inner face can be hung over, the faying face of packing and polished rod can be thus played,
The hardness of packing is strengthened, and faying face is close, then can reach that packing is difficult leakage.The present invention need not stop well and change for a long time
Polished rod or packing, but the leakage control of polished rod and packing is completed during oil well normal production operation, operation difficulty,
Workload, economic loss are significantly reduced, and are difficult leakage, oil mining efficiency high.
