Abstract
The invention discloses a mechanism having a paraffin scrapping function and a righting function simultaneously. The mechanism comprises a righting body (1) and a paraffin scraper (2). The paraffin scraper (2) further comprises a sleeve (21), a blade (22) and a connecting rod (24). The lower end of the righting body (1) is connected with the upper end of the paraffin scraper (2) through the connecting rod (24). An inner layer of the sleeve (21) is fixed to the connecting rod (24). The blade (22) is arranged on an outer layer of the sleeve (21). The problems that in the prior art, regular paraffin removal construction is complex, a delayed construction period is long and a paraffin scraping device is complex are solved, paraffin is scraped while oil pumping operations are performed, the mechanism has the righting function, a paraffin scraping device is simplified, paraffin scraping efficiency is improved, and a pipeline and a suction rod can be protected better.
Description
Technical field
The present invention relates to oil recovery aid field, particularly to a kind of mechanism with paraffin cutting and righting function.
Background technology
At present, during oil exploitation, oil is in gathering line due to the change of the external conditions such as temperature, pressure, meeting
Have waxiness, asphalitine etc. to separate out, be attached on inner-walls of duct formed cementing, with the prolongation of production time, can progressively reduced set
The problems such as flow area of defeated pipeline, formation line clogging or discharge pressure raise, and it is easily damaged sucker rod, bring to production
Difficult.
In the construction of operation well, paraffin cutting operation is requisite, and the method removing the long-pending wax of tube wall common at present has
Mechanical paraffin removal, blowing or gas-lift well can use paraffin scraper or paraffin bit, and pumpingh well commonly uses rod scraper, regular wax removal.
But each required time of above-mentioned wax removing method is long, equipment is complicated, and construction is loaded down with trivial details, and periodic cleaning is due to cannot control
The wax deposition speed of pipeline is it is impossible to accomplish timely wax removal, and can not preferably protect sucker rod and pipeline.
Content of the invention
The present invention is to overcome the wax removing construction operation time long, and wax removing equipment is complicated, loaded down with trivial details defect of constructing, and provides a kind of extension
Wax centralizer.
For reaching above-mentioned purpose, the present invention is using following scheme:
A kind of mechanism with paraffin cutting and righting function, including centralizer body and paraffin scraper；Paraffin scraper also includes sleeve, blade
And connecting rod；Centralizer body is connected by described connecting rod with paraffin scraper；Sleeve is fixed in connecting rod；Blade is arranged on sleeve
On.
Further, sleeve section is divided into inside and outside two-layer in concave shape structure, and its internal layer is enclosed within connecting rod, by fastening
Layer character cut in bas-relief open side makes sleeve fix with connecting rod, forms an open space, be easy to wax stone during wax removing between outer layer and internal layer
Can be dropped by this space, exclude outside well with circulation fluid, it is to avoid the wax stone scraping is piled up on paraffin scraper, increase sucker rod and pipe
The frictional force of wall, causes to sucker rod and pipeline to damage.
Further, blade is arranged on the outer layer of sleeve, and along its circumference distribution, tube wall is removed in the motion with sucker rod
On wax.
Preferably, blade is in the rim of a bowl shape, and tube wall circumferencial direction can be carried out with the cleaning of maximum area.
Preferably, paraffin scraper is connected to centralizer body lower end, it is to avoid the wax stone removed drops to be formed on centralizer body and piles up, and increases
Plus the frictional force of centralizer body and tube wall.
Further, the external diameter of paraffin scraper is more than the external diameter of centralizer body, enables paraffin scraper effectively to carry out wax body to tube wall clear
Remove.
The invention has the following beneficial effects: overall structure of the present invention is simple, facilitate implementation, low cost, the present invention scrapes
Wax device and centralizer are wholely set, small volume, stabilized structure, while righting, tube wall can be hung during present invention application
Wax operation；The present invention carries out wax removing while oil pumping, substantially prolongs the cycle of regular wax removing, shortens the duration, improves
Paraffin cutting efficiency.

Specific embodiment
For making the object, technical solutions and advantages of the present invention become more apparent, with reference to embodiment and accompanying drawing, to this
Invention is described in further detail, and the exemplary embodiment of the present invention and its explanation are only used for explaining the present invention, do not make
For limitation of the invention.
Embodiment 1
As shown in Figures 1 and 2, a kind of mechanism with paraffin cutting and righting function, including centralizer body 1 and paraffin scraper 2；Described
Paraffin scraper 2 also includes sleeve 21, blade 22 and connecting rod 24；Described centralizer body 1 is with paraffin scraper 2 by described connecting rod 24 even
Connect, the upper end of paraffin scraper 2 is connected with the lower end of centralizer body 1；Described sleeve 21 is fixed in connecting rod 24, the internal layer set of sleeve 21
In connecting rod 24, fastened by forming from steel wire；Described blade 22 is arranged on sleeve 21, blade 22 along sleeve 21 by upper under
Distribution is multiple；The external diameter of paraffin scraper 2 is slightly larger than centralizer body 1 external diameter.
Work process of the present invention is as follows: the present invention, in pumping operation, moves with the motion of sucker rod, centralizer body 1
Sucker rod is played with centralizing function, when moving to well head direction, blade 22 wipes the wax stone of tube wall off with motion to paraffin scraper 2.
Embodiment 2
For making effective wax removing area increase further, reduce resistance, on the basis of embodiment 1, blade 22 is shaped as the rim of a bowl shape,
It hangs wax scope close to circumference, and extension wax area is bigger compared with the paraffin scraper area of other forms, and the rim of a bowl shape then can reduce downward fluid
Resistance is it is ensured that the present invention more moves ahead in the duct glibly it is ensured that efficient, the stability that work.
Above-described specific embodiment, has been carried out to the purpose of the present invention, technical scheme and beneficial effect further
Describe in detail, be should be understood that the specific embodiment that the foregoing is only the present invention, be not intended to limit the present invention
Protection domain, all any modification, equivalent substitution and improvement within the spirit and principles in the present invention, done etc., all should comprise
Within protection scope of the present invention.
