Description
Technical field：
The utility model is related to oil-water well workover treatment technical field, more particularly to a kind of workover treatment wellbore treatments work
Tool.
Background technology：
Pit shaft is detected and processed in advance in workover rig service to oil well, it is necessary to before operation, well bore face is scraped off
The debris such as borehole burr, cement sheath, hard wax, it is to avoid the working condition of debris influence fishing string decentralization and fishing tool, cause
Down-hole accident.Treatment pit shaft is mainly using first descending the jack rabbit to carry out drifting at present, then setting of casing scraper is wiped off on casing wall
Debris, it is necessary on put that to put tubing string each twice.When processing pit shaft in bailing well fishing, if put on existing gauguste cutter
Excessive velocities are put, suction and top spray effect is easily formed, environmental pollution accident occurs.
Utility model content：
The technical problems to be solved in the utility model is to provide a kind of workover treatment wellbore treatments instrument, the arrangement achieves
Reduce to put and put tubing string number of times, it is to avoid put on gauguste cutter and suction and top spray phenomenon occur when putting excessive velocities, it is to avoid hair
Raw environmental pollution accident, improves fishing success rate, reduces operating cost.Overcome existing pit shaft drifting and scraping well
Wall needs to put puts each deficiency for putting easy generation suction and top spray phenomenon when putting excessive velocities twice, on gauguste cutter of tubing string.
Technical solution adopted in the utility model is：A kind of workover treatment wellbore treatments instrument, including tool body；Work
Tool body central is provided with hydrophthalmia, and tool body upper end is designed with top connection, and tool body lower end is designed with lower contact, tool body
Upper end outer wall is designed with latus rectum mechanism, and multiple tracks cannelure, the tool body of latus rectum mechanism bottom are machined with latus rectum mechanism outer wall
On be designed with scraping mechanism, scraping mechanism is made up of epimere scraping tooth and hypomere scraping tooth, epimere scraping tooth and hypomere scraping tooth
Tool body outer wall half-turn is in staggered distribution and is respectively distributed to, epimere scraping tooth and hypomere scraping tooth are equiangularly arranged by three
Scraping tooth composition.
The beneficial effects of the utility model are：The utility model realizes to reduce to put puts tubing string number of times, it is to avoid logical
Put on well rule and suction and top spray phenomenon occur when putting excessive velocities, it is to avoid environmental pollution accident occurs, fishing is improve
Success rate, reduces operating cost.
Brief description of the drawings：
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the present utility model.
Specific embodiment：
As shown in figure 1, a kind of workover treatment wellbore treatments instrument, including tool body 1；The center of tool body 1 is provided with water
Eye, the upper end of tool body 1 is designed with top connection 2, and the lower end of tool body 1 is designed with lower contact 5, and lower contact 5 can connect sand washing
Nib, top of fish top capable of washing during fishing.The upper end outer wall of tool body 1 is designed with latus rectum mechanism 3, and latus rectum mechanism 3 is this
At the maximum outside diameter of instrument.Multiple tracks cannelure is machined with the outer wall of latus rectum mechanism 3, is set on the tool body 1 of the bottom of latus rectum mechanism 3
In respect of scraping mechanism 4, scraping mechanism 4 is made up of epimere scraping tooth and hypomere scraping tooth, and epimere scraping tooth and hypomere scraping tooth are wrong
Open distribution and be respectively distributed to the outer wall half-turn of tool body 1, epimere scraping tooth and hypomere scraping tooth are equiangularly arranged by three
Scraping tooth composition.
Cannelure is provided with the outer wall of latus rectum mechanism 3, in the utility model is with fishing string decentralization process, can be kept away
It is tool-free due to above put put excessive velocities cause suction and top spray phenomenon, be prevented effectively from the generation of environmental pollution accident.By
The scraping tooth that vulcanie is constituted is with can be by the hard wax on well bore wall, the scraping of viscous crude block into chip, chip in tubing string decentralization process
As the decentralization of tubing string is squeezed into more than linkage section of the instrument with tubing string from the cannelure of latus rectum mechanism 3.Latus rectum mechanism 3 can be in pipe
Verify pit shaft whether there is undergauge, fracture dislocation in post decentralization process at any time.Whole tool interior is provided with hydrophthalmia, by pump truck on ground
To carrying out high pressure water injection in tubing string, high-pressure fluid is rinsed by the sand-washing pen point that the lower contact 5 of instrument is connected to pit shaft, will
The scrapings of tubing string and instrument linkage section recycle well head, complete the treatment of the debris such as hard wax, incrustation scale, viscous crude block to pit shaft
Work.
It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate the utility model and not
The technical scheme described by the utility model embodiment is limited to, it will be understood by those within the art that, still can be with
The utility model is modified or equivalent, to reach identical technique effect；As long as satisfaction uses needs, all in this reality
Within new protection domain.
