Description
Technical field
Well completion packer slips technical field is the utility model is related to, more particularly to a kind of new well completion packer card
Watt.
Background technology
Packer refers to for sealing annular space and (or) isolation interval of interest, control injection or extraction fluid, and can bear
The downhole tool of pressure difference.At present, HTHP completion practice carries out completion operation operation using well completion packer.Well completion packer
That a kind of pitching with bi-directional slip grappling sets permanent packer, due to high temperature high pressure deep well pressure in production process,
Temperature is widely varied, particularly perforation, pressure break, closing well, the operating mode such as drive a well alternate change under, existing well completion packer
There is mobile phenomenon, have impact on completion efficiency, increase the risk of completion tubular column destruction and pit shaft blowby.From field application and
From the point of view of well completion packer slips structure design, existing well completion packer slip design is unreasonable, such as tooth between cog angle design,
The fracture of slips body not thoroughly, rapidoprint selection it is improper etc., cause slips tooth to bite tubing depth smaller, it is difficult to play anchor
Fixed tube post effect.
The content of the invention
In order to overcome above-mentioned problems of the prior art, the utility model provides a kind of new well completion packer card
Watt, the slips is Integral C-shape slips, is divided under hydraulic action, so as to realize the grappling between slips and sleeve pipe, tooth form is set
Meter is unique, can improve well completion packer stability, reduces failure risk, has the characteristics of simple in construction, convenient and practical.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of new well completion packer slips, including slips body 1, described slips body 1 is C-shaped ring structure, described
The outside upright of slips body 1 be provided with and can will be broken groove 3 outside the slips of slips segmentation, be broken outside slips between groove 3 and be
Slip insert 2, the inner vertical of slips body 1 are provided with fracture groove 4 in slips, are broken outside described slips in groove 3 and slips
The fissure of displacement of groove 4 is broken to set；
The described upper surface of slip insert 2 is provided with crest angle and tooth inclination angle, in the lower surface end of slip insert 2 and slips body
1 contact position is provided with the key groove of certain angle.
Groove 3 is broken outside described slips and is respectively arranged with five with fracture groove 4 in slips.
Groove 3 and fracture 4 non-uniformity setting of groove in slips are broken outside described slips.
Inclination angle on described slip insert 2 is 65 °.
Drift angle on described slip insert 2 is 75 °.
The slips key groove of described slip insert 2 is designed as 15 °.
The beneficial effects of the utility model：
Slips is shaped as c-type structure, and sleeve pipe, slips and sleeve pipe will not be bitten in advance because of scratch sleeve pipe during going into the well
Contact stress be uniformly distributed vertically, packer slip volume is moderate, and slips preferably can be bitten among sleeve pipe, work more
Add reliable.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model slips tooth form figure.
Embodiment
The utility model is elaborated below in conjunction with the accompanying drawings.
Such as Fig. 1, a kind of new well completion packer slips includes slips body 1, slip insert 2, and slips is broken groove 3, card outside
Groove 4 is broken in watt.The slips is c-type monoblock type slips.The selection of the material of slips body 1 is mild steel, and outer surface is oozed
Carbon is handled to strengthen occlusion ability.It is non-uniformity that groove 3 is broken outside slips with fracture groove 4 in slips, with this according to liquid
Gradually fracture and then segmentation bite sleeve pipe to the difference of pressure, to reach more preferable anchoring effect.Slips integral design uses C
Type is designed, and this will not be strutted in advance when designing running string because of reducing in sleeve pipe, and c-type structure can be received in the presence of low-force
Contracting, avoids packer slip work ahead.
As shown in Fig. 2 the slips key groove of slip insert 2 is designed as 15 °, 10 ° and 20 ° of key grooves, slips and sleeve pipe are contrasted
Contact stress is axially distributed to be better than 20 ° of key grooves, and 10 ° of key grooves increase stroke, virtually add packer volume.Slips
Tooth inclination angle is designed as 65 °, contrasts 60 °, 65 °, 70 °, 75 °, 80 ° of five kinds of tooth angled state lower slipses stressing conditions respectively, obtains
The smaller slips in tooth inclination angle more easily bites the conclusion of sleeve pipe.Consider that packer may bear huge axial direction load during operation
Lotus, it is unfavorable for packer during 60 ° of tooth inclination angle and bears axial load slips equivalent stress is higher simultaneously, therefore slip insert inclination angle is compared
Rational angle is between 65 ° -70 °.Crest angle is designed as 75 °, contrasts 70 °, 75 °, 80 °, 85 °, 90 ° of five kinds of angle teeth respectively
Drift angle, it is found that what 75 ° of crest angle slips can be more firm is anchored on sleeve pipe, and avoid excessive plastic deformation.
During work, because the pitching slip insert that builds the pressure is broken in succession, slips tooth form can reduce card after optimization design by analysis
Watt plastic deformation danger, effectively can be anchored on again on casing wall, reduce packer slip failure risk
Operation principle of the present utility model：
Before packer tripping in underground work, install packer by packer installation standard and whether check each part
It is intact.Required according to well-completing process, by well completion packer tripping in appointed part.After tripping in appointed part, steel ball is put into completion
Among packer ball seat, by being suppressed in pipe, make packer piston stroking upward, sphenoid is up in the presence of hydraulic coupling and makes envelope
It is broken step by step along fracture groove every slips, sleeve pipe is slowly bitten in the presence of piston force, so as to reach grappling effect, according to upper
State operation and complete packing grappling.After the completion for the treatment of operation, to unseal well completion packer, tripping in special jewel grinder tool grinds off packer
Slips is removing seal for packer.
