Description
Technical field
Oil downhole operation equipment field is the utility model is related to, specially a kind of injection well tubing scraping Wax remover.
Background technology
During oil extraction in oil field, the wax in oil can separate out with the change of temperature, pressure from crude oil, be deposited on
Oil pipe, sucker rod surface, the wax control paraffin removal in oil well production process are always to perplex the technical barrier that oil field normally produces.It is existing
Anti-wax technique mainly includes：Hot wash wax control, paraffin control with inhibitor, electromagnetism wax control etc., wherein chemical paraffin removal, auxiliary hot wash workload is big,
Need technical staff that there is good technical foundation, paraffin removal decreased effectiveness even disappears electromagnetism paraffin removal after a certain period of use time,
Cost is high, and disposable Meteorological is more, and hot wash is big except wax contamination；And no matter which kind of wax control means taken, have wax deposition
On oil pipe surface.In use, tube inner wall can also fouling, salt crust so that pipe aperture attenuates, and influences oil well for oil pipe
Normal production, when existing water injection well scraper removes the wax on tube inner wall, easily to oil pipe pipe when cleaning intensity is larger
Wall causes to wear, and because wax is easily adhered on tube wall not easy-clear.
The content of the invention
To solve the above problems, the utility model discloses a kind of injection well tubing scraping Wax remover.
In order to reach object above, the utility model provides following technical scheme：A kind of injection well tubing scraping Wax remover,
Including the scraping blade salvaged axle, be arranged on salvaging axle bottom, ball seat, the ball are fixed with by latch in the salvaging axle
Seat upper end, which coincide, is provided with spheroid, and the axle of salvaging is provided with some grooves, and the groove is U-shaped opening groove, the U-shaped opening
The opening of groove is provided with baffle plate, and the baffle plate setting is slightly inclined to the position in groove, the lower end of the baffle plate in opening
Salvaging axle is fixedly connected with, gap is left between the baffle plate upper end and groove, the baffle plate side connects cavernous body.
Further, the baffle plate connects cavernous body by fixed block, and the fixed block is shorter in length than sponge body length,
The upper end of the cavernous body is consistent with the open upper end position height of groove.By the upper of the upper end level of cavernous body and slot opening
End height is consistent, and can effectively avoid spilling of the chemical wax removing agent before going into the well in groove, and fixed block is set shorter, convenient
Baffle plate is extruded after cavernous body stress.
Further, the lower end of the baffle plate is bolted to connection salvaging axle, and the baffle plate is elastic baffle.Elasticity
Baffle plate is made of elastomeric material, has stronger restoring force and elasticity, recyclable to be used for multiple times.
Further, 4 groups of grooves are circumferentially arranged with the salvaging axle.
Further, the scraping blade is taper blade, and cutter tooth is provided with the taper blade.When salt is in oil pipe
On wall, crystallization sometimes forms larger block, and salt crystallization hardness is larger, and scraping blade is difficult under disposable scraping sometimes
Come, cutter tooth effectively salt larger under scraping can crystallize block.
Operation principle of the present utility model：Chemical wax removing agent is injected in groove, sponge stress is interior backward to extrude fixed block,
Baffle plate is inwardly promoted, due to leaving gap between baffle plate upper end and groove, chemical wax removing agent in groove is from clearance flow between upper end
Go out, adsorb on cavernous body, by the rubbing action of cavernous body and tube inner wall, remove and do not scraped on tube inner wall by scraping blade
Cut clean residual oil wax.Baffle position slightly inward, rather than is arranged at the edge of opening of groove, cavernous body slightly protruding,
When cavernous body enters in well with scraper, sponge is inwardly extruded slightly, facilitates sponge to enter in well.
The utility model beneficial effect：1st, cavernous body effectively adsorbs wax removing agent, the oily wax of cleaning superpower to tube inner wall；Paraffin removal
Effect is good, and greatly reduces the use of chemical wax removing agent, effectively alleviates pollution of the chemical wax removing agent to environment, while cavernous body
Friction to tube inner wall is not easy that oil pipe is caused to wear, and extends oil pipe service life；2nd, in the effective scraping oil pipe of scraping blade
Fouling, salt matter, oily wax, shaving effect is good, and speed is fast；3rd, the utility model new structure is set reasonable, easy to use, operation
Simply, paraffin removal effect is good, the basic noresidue oil wax of the oil pipe after cleaning.
Brief description of the drawings
Fig. 1, structural representation of the present utility model；
The fixed connection structure schematic diagram of baffle plate and groove in Fig. 2, the utility model.
Reference numerals list：Salvage axle 1, scraping blade 2, latch 3, ball seat 4, spheroid 5, groove 6, baffle plate 7, cavernous body 8,
Fixed block 9, fixed seat 10, bolt 11, cutter tooth 12.
Embodiment
With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate, it should be understood that following specific embodiment parties
Formula is merely to illustrate the utility model rather than limitation the scope of the utility model.
A kind of injection well tubing scraping Wax remover as shown in Figure 1 and Figure 2, including salvage axle 1, be arranged on and salvage axle bottom
Scraping blade 2, salvage in axle and ball seat 4 be fixed with by latch 3, ball seat upper end, which coincide, is provided with spheroid 5, and salvaging axle is provided with
