Description
Technical field
It the utility model is related to the horizontal well operations downhole tool in oil development technical field.
Background technology
Oilfield horizontal well production technique has begun to sizable application at present, and wax deposition serious problems, operation occurs in part well
During need increase paraffin cutting process.Because horizontal well paraffin cutting is at present without special paraffin cutting instrument.The method being usually taken is to use
Straight well megaphone-shaped paraffin scraper, there are the following problems in application process:Because tool external diameter is big, profile is horn-like, can not arrive down
Horizontal segment, it is impossible to carry out horizontal segment paraffin cutting, have impact on horizontal well operations paraffin cutting effect.
The content of the invention
In order to solve the problems, such as in background technology, the utility model provides a kind of special paraffin cutting instrument of horizontal well, improves water
Horizontal well operation paraffin cutting effect.
For achieving the above object, the technical solution adopted in the utility model is:A kind of oil field operation horizontal well paraffin cutting
Device, including central tube, on scrape wax body and under scrape wax body, the central tube upper port is threadedly coupled oil pipe, lower port threaded connection
Starting taper, it is described on scrape wax body and resemble a pear in shape, upper paraffin cutting external surface is provided with some horizontal fins, and idol is circumferentially equipped with along wax body is above scraped
Several longitudinal breach, under to scrape wax body identical with the planform for above scraping wax body, above scrape wax body and under scrape wax body and be interference fitted respectively
On central tube, and on scrape the longitudinal breach of wax body and the longitudinal breach of wax body are scraped with mutually stagger in the circumferential, two paraffin cuttings
Some de-waxing holes are evenly distributed on central tube between body, above scrape wax body and under scrape the two of which adjacent transverse fin of wax body
Between be evenly distributed some paraffin cutting holes, and connection paraffin cutting hole and central tube are set on the correspondence position of center tube wall respectively
Paraffin cutting through hole.
Preferably longitudinally the quantity of breach is four.
The longitudinal breach of wax body are scraped on it is preferred that to scrape the longitudinal breach of wax body with mutual offset angular is 45 ° in the circumferential.
It is preferred that the quantity in de-waxing hole is four.
It is preferred that scraped on upper wax body and under the paraffin cutting hole number scraped in wax body be four.
The beneficial effects of the utility model:The paraffin scraper structure and shape are beneficial to pass through horizontal well well section, and ground utilizes pump
Ground is returned to after the wax that scraped off can be rinsed after car hot water circuit, can effectively prevent paraffin cutting tubing string jam, paraffin cutting efficiency high.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model oil field operation horizontal well paraffin scraper.
Fig. 2 is the A-A views in Fig. 1.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings:
As shown in Fig. 1 combinations Fig. 2:A kind of oil field operation horizontal well paraffin scraper, including central tube 1, on scrape wax body 2 and under scrape
Wax body 5, the upper port of central tube 1 are threadedly coupled oil pipe, lower port threaded connection starting taper, it is described on scrape wax body 2 and resemble a pear in shape, on
Scrape the outer surface of wax body 2 and be provided with 5 horizontal fins 22, wax body 2 is circumferential to be equipped with four longitudinal breach 21 along above scraping, under scrape wax body 5
It is identical with the planform for above scraping wax body 2, above scrape wax body 2 and under scrape wax body 5 and be interference fitted in respectively on central tube 1, and on scrape
The longitudinal breach 21 that the longitudinal breach 21 of wax body 2 scrape wax body 5 with mutually stagger 45° angle in the circumferential, and two are scraped between wax body
Central tube on be evenly distributed four de-waxing holes 3, above scrape wax body 2 and under scrape the two of which adjacent transverse fin 22 of wax body 5
Between be evenly distributed four paraffin cutting holes 4, and connection paraffin cutting hole 4 and central tube are set respectively on the correspondence position of center tube wall
Paraffin cutting through hole.
The wax body of scraping of the paraffin scraper is designed as 2 pyriform Split type structures, and specification is identical, and the longitudinal breach of the two are in circumference
Upper staggeredly 45 ° of distributions, are convenient for multi-angle paraffin cutting;Ground pump truck carries out hot water circuit and replaces out and scrape by paraffin cutting hole and de-waxing hole
Under wax and ground is returned to after flushing;Its underpart connects starting taper, is easy to pass through horizontal segment, and upper design is into pipe wire
Button, is connected with paraffin cutting tubing string.
Horizontal well paraffin scraper is issued to the horizontal well horizontal segment position of wax deposition with paraffin cutting tubing string, utilizes paraffin cutting tubing string weight band
Dynamic horizontal well paraffin scraper carries out paraffin cutting, and 2 pyriforms scrape the wax on wax body scraping sleeve pipe, at the same ground with cement pump truck replace into
Hot water circuit, the wax scraped off from sleeve pipe is recycled to surface line by de-waxing hole, ceratuba post to be doctored passes through wax deposition well section
After depth, terminate paraffin cutting, ensure that operation paraffin cutting process is carried out.
