Abstract
The utility model provides a kind of oil pipe latus rectum scraper, comprise the joint of cylindrical body and the setting of body two ends, described body is provided with some groups of scraping blades, scraping blade tapered circular, two be one group, the small end laminating often organizing scraping blade is arranged on body side face, large end oppositely installs setting.The utility model oil pipe latus rectum scraper, structure is simple, with low cost, use this instrument, only need operating personnel, can easily synchronously complete latus rectum and scraping, operating principle is simple, operation walk away safety reliably, can fast and effeciently clear up tube inner wall dirt, impurity etc., guarantee that tube inner wall is clean, practicality and high efficiency, for later stage production and construction provides powerful guarantee, improves construction quality, be beneficial to and use on a large scale and promote, there is wide using value.
Description
Technical field
The utility model relates to the well workover aid in oil gas field, specifically a kind of when oil pipe latus rectum process, the oil pipe latus rectum scraper of latus rectum and scraping institutional operation can be realized.
Background technology
In Downhole Construction process, because oil pipe is removing in process, easily on tube inner wall, adhere to the impurity such as cement, hard wax, mud, meanwhile, because impurity etc. cut by iron, easily adhere on tube inner wall, after causing oil pipe blocking or tube inner wall to adhere to, latus rectum reduces, and affects carrying out smoothly of later stage operation, has both added construction operation risk, have impact on again integral construction quality, add post-processed cost.
The oil pipe latus rectum device of prior art as shown in Figure 1, oil pipe latus rectum device body two ends are provided with slightly wider than the device for scraping of body side face, but because device for scraping does not adopt blade unit structure, cause when oil pipe latus rectum, effectively cannot remove impurity or the rusty stain of tube inner wall.
Summary of the invention
The purpose of this utility model is: provide a kind of oil pipe latus rectum scraper, when oil pipe latus rectum process, realizes latus rectum and scraping institutional operation, guarantees that tube inner wall is clean.
The technical scheme that the utility model adopts is:
Oil pipe latus rectum scraper, comprise the joint of cylindrical body and the setting of body two ends, described body is provided with some groups of scraping blades, scraping blade tapered circular, two be one group, the small end laminating often organizing scraping blade is arranged on body side face, large end oppositely installs setting.
Described scraping blade and body removably connect.
Described scraping blade cone-shaped ring face and body shaft to angle be 70 ~ 80 °.
Described scraping blade has three groups, is arranged in the epimere of body, stage casing and hypomere.
The beneficial effect that the utility model produces is:
The utility model oil pipe latus rectum scraper, structure is simple, with low cost, use this instrument, only need operating personnel, can easily synchronously complete latus rectum and scraping, operating principle is simple, operation walk away safety reliably, can fast and effeciently clear up tube inner wall dirt, impurity etc., guarantee that tube inner wall is clean, practicality and high efficiency, for later stage production and construction provides powerful guarantee, improves construction quality, be beneficial to and use on a large scale and promote, there is wide using value.

Fig. 3 is the left TV structure schematic diagram of Fig. 2;
Number in the figure represents: 1-body, 2-scraping blade, 3-joint.
Detailed description of the invention
As shown in Figure 2,3, the utility model is a kind of oil pipe latus rectum scraper, comprises the joint 3 of cylindrical body 1 and the setting of body 1 two ends.Body 1 is provided with some groups of scraping blades 2, scraping blade 2 tapered circular, two be one group, the small end laminating often organizing scraping blade 2 is arranged on the outer peripheral face of body 1, large end oppositely installs setting.
Scraping blade 2 is tapered circular, and its knife face can be along tiltedly the facing directly of annulus radial direction, also can be the curved surface with certain radian, and this cambered surface is radial along annulus, to the taper small end indent of scraping blade 2.The angle of scraping blade 2 cone-shaped ring face and body 1 axis is 70 ~ 80 °, and the angle of the utility model preferred scraping blade 2 cone-shaped ring face and body 1 axis is 70 °, 75 ° and 80 °.After the assembling of oil pipe latus rectum scraper, about the 2 ~ 5mm larger than institute's scraping pipe aperture of maximum outside diameter when cone-shaped ring shape scraping blade 2 is freely stretched out; During latus rectum, scraping blade 2 is compressed by tube inner wall extruding, inward collapsible, and its maximum outside diameter is then less than pipe aperture, makes it can put into oil pipe smoothly.
Scraping blade 2 and body 1 removably connect.In this detailed description of the invention, scraping blade 2 has three groups, and socket is arranged on the epimere of body 1, stage casing and hypomere respectively.The number of scraping blade 2, position and mounting means, can according to the situation of tube inner wall, self assemble dismounting.
Using method of the present utility model is as follows:
When using the utility model oil pipe latus rectum scraper to carry out oil pipe latus rectum, scraping blade 2 has certain deformability, under the squeezing action of the attachment on tube inner wall, inward collapsible compression, it is descending that tube inner wall is close in the periphery of scraping blade 2, carries out scraping to tube inner wall.
