Abstract
The utility model provides a sleeve pipe scraper anticreep connects, belong to a oil field production apparatus, it takes the top connection of internal screw thread shaft type, the upper portion of intermediate junction cover is located the inboard of top connection lower part and links together with the top connection, the upper portion of shaft type lower clutch is located the inboard of intermediate junction cover and top connection, there is first latch at the middle part of lower clutch, the lower extreme of intermediate junction cover has the second latch that corresponds with first latch, there is the external screw thread lower part of lower clutch, the lower clutch upper end is fixed with and keeps off the ring. This kind of anticreep connects, and during the use, scraper upper portion is passed through the screw thread and is installed in the lower part of lower clutch, reciprocal scrape with the tripping operation petroleum string in -process, when the tubular column turn back, the lower clutch of installing the scraper dallies, the threaded connection between lower clutch and the scraper can not become flexible, has avoided the scraper to drop in the use, has prevented that the scraper from threading off the well and the downhole accident that causes, the scraping finishes and to play out the pit shaft safely. Accelerate job progress, reduced the operating cost.
Description
Technical field
This utility model provides a kind of oil field and produces apparatus, especially a kind of joint.
Background technology
In oilfield process, the fouling of internal surface of sleeve pipe, burr etc. must carry out the cleaning of scraping repeatedly with scraper, smooth to reach internal surface of sleeve pipe.Owing to existing pipeline scraper top connection outer surface is trapezoid buckle, after being connected with scraper, it is easy to release.After going into the well, internal surface of sleeve pipe is close to by blade, and in reciprocal scraping and lift pipe string process, the reversal development of tubing string easily causes screw thread and loosens, and causes that the de-mouth of scraper falls well, causes the accident.Scraper falls and not easily salvages after well.
Summary of the invention
Technical problem to be solved in the utility model has been to provide a kind of casing scraper retaining connector, to avoid scraper in use to come off.
This utility model is realized in, casing scraper retaining connector, it has the top connection of tapped tubular, the top of intermediate connecting sleeve is positioned at the inner side of top connection bottom and links together with top connection, the top of the lower contact of tubular is positioned at the inner side of intermediate connecting sleeve and top connection, and there is the first latch at the middle part of lower contact, and there is second latch corresponding with the first latch the lower end of intermediate connecting sleeve, external screw thread is arranged at the bottom of lower contact, and lower contact upper end is fixed with baffle ring.
Adopt the casing scraper retaining connector of said structure, during use, scraper top is by being threadably mounted at the bottom of lower contact, in reciprocal scraping and a lower tubular column process, when tubing string reverses, the lower contact idle running of scraper is installed, threadeding between lower contact with scraper will not loosen, avoid scraper in use to come off, it is therefore prevented that scraper threads off well and the down-hole accident that causes, and scraping is complete can trip out pit shaft safely.Accelerate job scheduling, decrease operating cost.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model structure.
Detailed description of the invention
The embodiment provided below in conjunction with accompanying drawing further illustrates the concrete structure of utility model.
As shown in drawings, the casing scraper retaining connector of this utility model, it has the top connection 4 of tapped tubular, the top of intermediate connecting sleeve 2 is positioned at the inner side of top connection bottom and links together with top connection, the top of the lower contact 1 of tubular is positioned at the inner side of intermediate connecting sleeve and top connection, and there is the first latch 6 at the middle part of lower contact, and there is second latch 5 corresponding with the first latch the lower end of intermediate connecting sleeve, external screw thread is arranged at the bottom of lower contact, and lower contact upper end is fixed with baffle ring 3.
" second latch corresponding with the first latch " refers to, the shape of the second latch, size are corresponding with the first latch, make both can plug-in card together.
During use, working string is linked together by screw thread and top connection, and scraper top is by being threadably mounted at the bottom of lower contact.The joint of scraper and this utility model is driven down in sleeve pipe by working string, carries out the scraping of internal surface of sleeve pipe.When working string is descending, the first latch and the second latch plug-in card together, drive scraper to rotate, carry out scraping.When carrying under working string, under the effect that lower contact, scraper are conducted oneself with dignity, the first latch and the second latch separate, and baffle ring is stuck in the upper end of intermediate connecting sleeve.When reversal development occurs in working string, lower contact is dallied, and without influence on threadeding between scraper with lower contact, scraper does not come off.
