Abstract
The utility model is related to a kind of water filling device, specially a kind of pair guide eccentric injection well downhole flow regulator, including the top connection being sequentially connected, branch sleeve, main body and lower guide way, top connection, branch sleeve, the maximum outside diameter ＜ 88mm of main body or lower guide way, guide way and guide way on being provided with branch sleeve, upper guide way are located at the upper end of guide way.Relative to prior art, the utility model is less than 88mm eccentric injection mandrel using external diameter, smoothly by the sleeve pipe after subsidy work can be enable normally to carry out.
Description
Technical field
The utility model is related to a kind of water filling device, specially a kind of pair guide eccentric injection well downhole flow regulator.
Background technology
At present, the internal diameter of domestic water injection well 5-1/2 " sleeve pipes is 124mm, and the injection well downhole flow regulator of this casing inner diameter is generally that external diameter is
115mm's.The internal diameter of 5-1/2 " sleeve pipes is 124mm under normal circumstances, and 114mm injection well downhole flow regulator is during transferring, rising
Very smoothly；But the long sleeve pipe of some use times, due to being influenceed by ground movement, well post can suffer oppression deformation；Again
By the long-time etch by downhole corrosion liquid, some positions of sleeve pipe can be corroded and cause perforation, now whole to ensure
The sealing of tubing string is accomplished by the site of perforation being corroded again by manually subsidizing one section of casing inner diameter for 88mm, and downhole tool is special
It is injection well downhole flow regulator, the radial dimension arrangement of hydraulic anchor is particularly thorny, and existing injection well downhole flow regulator has the problem of pulling is inaccurate, at present
The internal diameter for subsidizing sleeve pipe is generally 88mm or so；So when by the case of sleeve pipe and casing patching, the 115mm's of current version matches somebody with somebody
Hydrophone can not be by deforming and subsidizing a section sleeve pipe.
Utility model content
The technical problems to be solved in the utility model is：Casing deformation and after subsidizing, conventional injection well downhole flow regulator can not pass through；It is existing
There is small diameter water distributer fishing plugging device success rate low, to solve the above problems, providing a kind of pair of guide eccentric injection well downhole flow regulator.
The purpose of this utility model is realized in the following manner：
A kind of pair of guide eccentric injection well downhole flow regulator, including top connection, branch sleeve, main body and the lower guide way being sequentially connected, on
Joint, branch sleeve, the maximum outside diameter ＜ 88mm of main body or lower guide way, are provided with guide way and guiding in branch sleeve
Body, upper guide way is located at the upper end of guide way；Eccentric orfice is provided with top connection；Top connection, upper guide way, main body and lower guiding
The eccentric throw of body is identical；The guide direction of upper guide way and guide way is symmetrical arranged；Helicoid is provided with upper guide way.
The inclined hole path internal diameter≤45mm of main body in main body.
Guide way is bolted with main body.
Relative to prior art, the utility model is less than 88mm eccentric injection mandrel using external diameter, can smoothly passed through
Sleeve pipe after subsidy, enables work normally to carry out.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 is top connection；2 be upper guide way；3 be branch sleeve；4 be guide way；5 be blanking plug；6 be main body；7
It is lower guide way.
Embodiment
As shown in figure 1, a kind of pair of guide eccentric injection well downhole flow regulator, including be sequentially connected top connection 1, branch sleeve 3, main body 6
With lower guide way 7, top connection 1, branch sleeve 3, the maximum outside diameter ＜ 88mm of main body 6 or lower guide way 7, in branch sleeve 3
Guide way 2 and guide way 4 are provided with, upper guide way 2 is located at the upper end of guide way 4.Do not changing original outer diameter ruler of blanking plug 5
In the case of very little, the inclined hole path internal diameter≤45mm of main body in main body 6.The guide direction of upper guide way 2 and guide way 4 is symmetrically set
Put.Top connection 1, upper guide way 2, main body 6 are identical with the eccentric throw of lower guide way 7.Guide way 4 is bolted with main body 6.
The maximum outside diameter of blanking plug 5 used in existing pair of guide eccentric injection well downhole flow regulator is 22mm, this pair of guide eccentric injection well downhole flow regulator
In the case of original external diameter of blanking plug 5 is not changed, double guide eccentric injection well downhole flow regulator maximum outside diameters are designed as ＜ 88mm, its main body 6
The upper inclined hole size constancy of blanking plug 5, the inclined hole path internal diameter≤45mm of its main body.
Upper guide way 2 and guide way 4 are set to symmetrical structure, force feed device is salvaged in throw in catcher decentralization process advanced
Enter inside eccentric injection mandrel, by upper guide way 2, be subsequently directed to device entrance, guider is first in the spiral of upper guide way 2
Rotation is slided on face, is modified to salvaging force feed setting position, guider is slided on the upper helicoid of guide way 2 to be terminated,
Continuation is moved downward with throw in catcher main body, now, is salvaged force feed device and is started to contact the helicoid of guide way 4, carries out second
Amendment is put, force feed device is salvaged as throw in catcher main body is moved downward, moves to helicoid end, places stifled into guide way 4
Fill in the inclined hole of device 5, it is accurate to salvage force feed blanking plug 5.The structure salvages the position of force feed device by modified twice, makes its accurate
Salvage the blanking plug 5 in eccentric injection mandrel.
Top connection 1, upper guide way 2, guide way 4, main body 6, lower guide way 7 are set to unified eccentric throw, it is ensured that pulling
Device can pass through each inclined hole during force feed salvages blanking plug 5.
Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as
Protection domain of the present utility model.
