Set, the cartridge with the full bag enhancing set and the packer with the cartridge.
Background technology
Fig. 1 is the structural representation of upper end sealing ring, and Fig. 2 is that the cartridge with the upper end sealing ring is installed on sleeve pipe
And the structural representation between central tube.As shown in figure 3, when upper end sealing ring is softer, the top of upper end sealing ring can produce
Shoulder, the shoulder are very easy to the seal failure for causing cartridge because of pressure disruption.As shown in figure 4, work as upper end sealing ring
When harder, upper end sealing ring is not bonded with sleeve pipe/non-contravention and form gap, intermediate seal ring can move up in the gap
Form shoulder.The stress of cartridge in the axial direction is chronologically divided into two stages：First stage, cartridge is by from upper
Axial compressive force under and；Second stage, cartridge are acted on by high temperature and high pressure gas from bottom to top.Fig. 3 and Fig. 4 are shown
The deformation that the bottom of second stage posterior end sealing ring is upturned.
9th phase in 2002《Petroleum machinery》Disclose《Packer compresses packing element " protrusion-dispelling " new construction》, wherein recording
Following content：" due to anti-lug structure be for covering the annular gap between packer and sleeve pipe, during packer setting, once glue
Cylinder deformation contacts with casing wall, and under load effect outside, outburst prevention device is with regard to the unfolded annular space covered between packer and casing wall, resistance
Only packing element is towards prominent in this annular space, forces packing element to uniform compression, to produce and keep the higher contact stress of packing element in each,
So as to obtain good sealing "." ... mainly there are copper bowl curing type and steel mesh or two kinds of steel band curing type.The former is by two
Copper bowl thick 2mm is solidificated on two end packing element end faces respectively, and the latter is that thick 1mm or so steel mesh or steel band is solid respectively
Change and held at two on packing element end face ".According to above-mentioned record, copper sheathing can be coated in the upper part of upper end sealing ring, to prevent
Only upper end sealing ring produces shoulder：If copper sheathing is thicker, upper end sealing ring radially extends deficiency when axial compressive force acts on, copper sheathing with
Gap between sleeve pipe be present, intermediate seal ring can shift up from the gap, be formed similar to the shoulder shown in Fig. 4, and upper end
Sealing ring can also produce less shoulder.When copper sheathing is relatively thin, upper end sealing ring radially extends abundance, copper sheathing under axial
It is bonded to each other with sleeve pipe in the absence of gap, but relatively thin copper sheathing can not prevent upper end sealing ring from producing the shoulder being similar to shown in Fig. 3
It is prominent.
Similarly, in the first stage, lower end sealing ring produces downward shoulder if lower end sealing ring is softer；If lower end is close
The bottom of the harder then intermediate seal ring of seal ring produces downward shoulder.Probably, second stage, lower end sealing are not proceeded to also
The shoulder of ring and the shoulder of intermediate seal ring have failed, so the selection of the soft or hard degree of lower end sealing ring is also highly desirable.
Although prior art also has the upper and lower ends in cartridge while sets the situation of copper sheathing, its purpose is to worker scene
It is easy for installation, it is reverse when preventing cartridge upper and lower ends from installing.
Generally, those skilled in the art can attempt to select suitable copper sheathing thickness, in the thickness, can prevent that end is close
The shoulder and can of seal ring prevents the shoulder of intermediate seal ring.Now, be installed on the copper sheathing of upper end sealing ring thickness be possible to
The thickness for being installed on the copper sheathing of lower end sealing ring is identical.

Embodiment
Fig. 5 shows that the application wraps the structure that enhancing set 1 is coated on upper end sealing ring 2 entirely, from fig. 5, it can be seen that full bag
Enhancing set 1 is coated to upper end sealing ring outer surface 21, upper end sealing ring upper ring surface 22 and anchor ring 23 under the sealing ring of upper end.Bearing
During axial compressive force, the lower surface of full bag enhancing set 1 is the lower surface of the lower convexity 13 after bending by the upper surface of intermediate seal ring 3
It is pressed against, complete wrap strengthens the rigid spacer ring that upper raised 12 upper surface after the upper surface for covering 1 is bent is applied in axial compressive force
It is pressed against, so full bag enhancing set 1 is fixed by intermediate seal ring 3 and rigid spacer ring substantially.Upper end sealing ring 2 needs to overcome entirely
The downward cladding power of bag enhancing set 1, shoulder 6 could be formed to raise up.So full bag is set to increase on upper end sealing ring 2
Strong set 1 can effectively prevent the generation of the shoulder 6 on upper end sealing ring 2.
The application is based on following thinking：The same of the downward cladding power of 1 pair of upper end sealing ring 2 is covered keeping full bag enhancing
When, reduce the restraint that full bag enhancing 1 pair of upper end sealing ring 2 of set radially extends.
Thus, in one embodiment of the application, there is provided a kind of suitable for upper end sealing ring 2 and lower end sealing ring 7
Full bag enhancing set 1.The work for being installed on the mounting means of upper end sealing ring 2 and lower end sealing ring 7 by full bag enhancing set 1 and rising
With being hereafter normally only illustrated with upper end sealing ring 2.
As shown in fig. 6, the full bag enhancing set 1 includes：
Elongated substrate 11, by the substrate first end 111 on the length direction of substrate 11, substrate the second end 112
And substrate pars intermedia 113 forms, substrate 11 needs around upper end sealing ring outer surface 21 and fitted therewith when in use.Work as base
When piece 11 fits with upper end sealing ring outer surface 21, substrate first end 111 is with substrate the second end 112 in upper end sealing ring
Overlapped on outer surface 21.
With upper raised the 12 of the sheet of the integrally connected of substrate top edge 114, when substrate 11 and upper end sealing ring outer surface 21
When fitting, upper raised 12 can be bent to be affixed with upper end sealing ring upper ring surface 22 towards the direction of upper end sealing ring through hole 24
Close.
With the lower convexity 13 of the sheet of the lower edge integrally connected of substrate 11, when substrate 11 and upper end sealing the phase of ring outer surface 21
During fitting, lower convexity 13 can be bent to be fitted with anchor ring 23 under the sealing ring of upper end towards the direction of upper end sealing ring through hole 24.
In this application, the shoulder problem of anti-the upper end sealing ring 2 and intermediate seal ring 3 to being difficult to take into account has carried out difference
The processing of change：Upper raised 12, the combination of lower convexity 13 and substrate 11 can prevent the generation of the shoulder 6 of upper end sealing ring 2.In order to
Reduce the hardness of upper end sealing ring 2, the application is provided with overlapping but individually separated substrate first end 111 and substrate
The second end 112, under axial upper end sealing ring 2 radially extending, substrate first end 111 and substrate the second end
112 intersection is gradually reduced, compared to substrate first end 111 and the integrative-structure of substrate the second end 112 or mutually weldering
Dead technical scheme, equivalent to the hardness for reducing upper end sealing ring 2, it is therefore prevented that the generation of the shoulder 6 of intermediate seal ring 3.
In this application, the intersection of substrate first end 111 and substrate the second end 112 is bigger, then close to upper end
The limitation radially extended of seal ring 2 is bigger, it is possible to adjusts the hard of upper end sealing ring 2 by adjusting the length of intersection
Degree.
Both if substrate first end 111 and substrate the second end 112 are misaligned on upper end sealing ring outer surface 21, i.e.,
Between gap be present, then upper end sealing ring 2 radially extends and causes the gap to increase under axial, and upper end sealing ring 2 more holds
Easily radially extended in gap location, cause radially extending for the entirety of upper end sealing ring 2 uneven, influence upper end sealing ring 2 to sleeve pipe 4
Uniform contact.Moreover, upper end sealing ring 2 is also easy in the gap location by substrate first end 111 and substrate the second end 112
Isolate, done so in this application sealing substrate first end 111 in upper end with substrate the second end 112 on ring outer surface 21
Overlap design.
Only overlapped on upper end sealing ring outer surface 21 in view of substrate first end 111 and substrate the second end 112 and
It is not fixedly connected, is fitted if being not provided with lower convexity 13 with anchor ring 23 under the sealing ring of upper end, full bag enhancing set 2 is almost to upper end
Seal ring outer surface 21 to act on without constraint, and then upper end sealing ring upper ring surface 22 is also acted on without constraint, full bag enhancing set 1
Do not produce downward cladding power to upper end sealing ring 2, do not have the effect for preventing upper end sealing ring 2 from producing shoulder 6.
Because upper end sealing ring outer surface 21 is curved surface, when being bent towards upper end sealing ring through hole 24, upper raised 12 with
Projection 13 easily produces fold, and this can be alleviated or avoided by reducing the shape of upper projection 12 and lower convexity 13.In Fig. 6 and
In embodiment illustrated in fig. 7, upper raised 12 and lower convexity 13 are rectangle, and quantity is four, in upper end sealing ring in Fig. 7
Adjacent upper raised 12 of upper ring surface 22 do not overlap, correspondingly under the sealing ring of upper end anchor ring 23 adjacent lower convexity 13
Also will not overlap.Exemplified by above projection 12, this is advantageous to the smooth of each raised 12 on upper end sealing ring upper ring surface 22,
So axial compressive force can by smooth upper raised 12 equably indirectly-acting in upper end sealing ring 2, make it evenly radially
Extension.In other embodiments, upper raised the 12 of other quantity can also be set, but the first gap between each raised 12
123 should ensure that when each raised 12 are bent to be fitted with upper end sealing ring upper ring surface 22 towards upper end sealing ring through hole 24
When, adjacent upper raised 12 do not overlap on upper end sealing ring upper ring surface 22.The quantity of lower convexity 13 could be arranged to 5
Individual, other quantity such as 7, but the second gap 133 between each lower convexity 13 should ensure that when each lower convexity 13 is by towards upper end
Sealing ring through hole 24 bending come with anchor ring 23 fits under the sealing ring of upper end when, adjacent lower convexity 13 ring under the sealing ring of upper end
Do not overlapped on face 23, each lower convexity 13 being equally beneficial under the sealing ring of upper end on anchor ring 23 it is smooth.
In Fig. 6 and embodiment illustrated in fig. 7, because each raised 12 only to the local complexity of upper end sealing ring upper ring surface 22,
It can only prevent certain part of upper end sealing ring 2 from producing shoulder 6, in order that upper end sealing ring 2 all no longer produces shoulder 6,
Need to make raised 12 wholes for covering upper end sealing ring upper ring surface 22 or at least cover outer anchor ring, the anchor ring is applied
The rigid spacer ring of axial compressive force is added to be pressed against.Following technical scheme is devised for this：
It is more than with the width of the upper raised connection end 121 of the integrally connected of substrate top edge 114 with substrate top edge 114 farther out
Upper raised free end 122 width, this includes：Upper raised 12 width is raised up free end 122 by upper raised connection end 121
It is gradually reduced；And upper raised 12 width is raised up the situation that free end 122 reduces suddenly by upper raised connection end 121, example
As above raised connection end 121 is made up of with upper raised free end 122 rectangle part of different sizes.
Fig. 8 shows that raised 12 width is raised up one kind that free end 122 is gradually reduced by upper raised connection end 121
Structure.Referring to Fig. 9, superposition length or so that adjacent of adjacent upper raised 12 on upper end sealing ring upper ring surface 22 is reduced
Upper raised 12 be not overlapped mutually on upper end sealing ring upper ring surface 22.In fig.9 each raised 12 with upper end sealing ring on ring
The all surfaces in face 22 are bonded, and in other embodiments, can also only be bonded outer anchor ring, it is ensured that apply axial compressive force
Rigid spacer ring each raised 12 can be pressed against.In one embodiment, pasted when each raised 12 with upper ring surface
During conjunction, two neighboring raised the distance between 12 are less than 2mm, thus between larger each raised 12 shown in Fig. 8
One gap 123 disappears substantially in state shown in Fig. 9.
Based on the reason for identical, lower convexity 13 is shaped as, the lower convexity connection end with the lower edge integrally connected of substrate 11
131 width is more than the width of the lower convexity free end 132 with the lower edge of substrate 11 farther out.In Fig. 8, the width of lower convexity 13 is under
The raised downwardly convex free end 132 in connection end 131 is gradually reduced.Referring to Fig. 9, when each lower convexity 13 with ring under the sealing ring of upper end
Face 23 be bonded when, the distance between two neighboring lower convexity 13 is less than 2mm, thus larger each lower convexity 13 shown in Fig. 8 it
Between the second gap 133 disappeared substantially in state shown in Fig. 9.Referring in Fig. 9 each raised 12 and upper end sealing ring upper ring surface
22 fitting situations understand that each lower convexity 13 is bonded with all surfaces of anchor ring 23 under the sealing ring of upper end in fig.9, other
In embodiment, outer anchor ring can also be only bonded, it is ensured that convex under the upper surface of intermediate seal ring 3 will be each when applying axial compressive force
13 are played to be pressed against.
Radially extend because upper end sealing ring 2 is compressed by axial compressive force and cause substrate first end 111 and the end of substrate second
The length of the intersection in portion 112 is gradually reduced, and in order to ensure that substrate 11 can coat upper end sealing ring outer surface 21 all the time, is needed
To be configured to overlapping length.Basic principle is, when radially extend full bag enhancing set 1 is fitted with sleeve pipe 4 when, substrate
Although first end 111 is still overlapped on upper end sealing ring outer surface 21 with substrate the second end 112 or misaligned but substrate
Gap between the end face of first end 111 and substrate the second end 112 is very small, is, for example, less than equal to 2mm.
If substrate first end 111 and substrate the second end 112 are respectively provided with raised 12 and lower convexity 13, in coincidence part
Point, upper raised the 12 of first end 111 are overlapped mutually with upper raised the 12 of the second end 113, the lower convexity of first end 111 13
It is overlapped mutually with the lower convexity 13 of the second end 113.On the one hand superposition is upper raised 12 higher, cause each raised 12 with it is upper
Out-of-flatness after end sealing ring upper ring surface 22 is bonded.On the other hand, upper raised the 12 of superposition are mutually close under axial compressive force effect
Fitting, generation obstruction can be radially extended to upper end sealing ring 2.Correspondingly, the lower convexity 13 of superposition also makes each lower convexity 13 exist
Out-of-flatness after being bonded with anchor ring 23 under the sealing ring of upper end, and generation obstruction is radially extended to upper end sealing ring 2.Therefore, such as
Shown in Fig. 8, raised 12 and lower convexity 13 are not provided with substrate first end 111.
The full bag enhancing set 1 of analysis is installed on the structure after upper end sealing ring 2 it can be found that due to substrate first end 111
On be not provided with raised 12 and lower convexity 13, and set on substrate the second end 113 upper raised 12 and lower convexity 13 with applying
The rigid spacer ring and upper end sealing ring upper ring surface 22 of axial compressive force compress respectively.Thus, substrate first end 111 is compared with substrate second
End 113 is easier to move, so radially extending process in upper end sealing ring 2, the substantially movement of substrate first end 111 comes
Reduce the process of intersection.For the ease of the movement of substrate first end 111, when substrate first end 111 and substrate second
When being overlapped on upper end sealing ring outer surface 21, substrate first end 111 is located remotely from upper end sealing ring through hole 24 for end 112
Outside and substrate the second end 112 are located at close to the inner side of upper end sealing ring through hole 24, because upper end sealing ring 2 is easier to make for
Radially extend, equivalent to the hardness for reducing upper end sealing ring 2, as described above, can prevent or reduce the generation shoulder of intermediate seal ring 3
Prominent 6.Certainly, if the hardness deficiency of upper end sealing ring 2, and cause itself to produce shoulder 6 under axial, then can be in substrate the
One end 111, when being overlapped on upper end sealing ring outer surface 21, substrate first end 111 is set with substrate the second end 112
To be located remotely from the outside of upper end sealing ring through hole 24 close to the inner side of upper end sealing ring through hole 24 and substrate the second end 112,
So substrate first end 111 is located between substrate the second end 112 and upper end sealing ring outer surface 21, due to being sealed in upper end
Ring 2 radially extends substrate first end 111 in process and is brought into close contact by substrate the second end 112 and upper end sealing ring outer surface 21
And very big friction is produced, radially extending for upper end sealing ring 2 is hindered, equivalent to the hardness for adding upper end sealing ring 2.By
In being not provided with upper raised 12 and lower convexity 13, when not applying axial compressive force, substrate first end on substrate first end 111
111 with upper end sealing ring 2 without any tie point, it is free state that this, which causes substrate first end 111, when substrate first end
111 positioned at substrate the second end 112 and upper end sealing ring outer surface 21 between when, add the tidiness of product and prevent base
Piece first end 111 produces scratch to operating personnel.
In one embodiment, the integrative-structure of substrate 11 as shown in Figure 6 is changed to, and substrate 11 includes multiple in length side
The lengthy motion picture being separated from each other upwards, the top edge of each lengthy motion picture connect a upper projection 12, and the lower edge of each lengthy motion picture connects one
Lower convexity 13.Each lengthy motion picture is centered around upper end sealing ring outer surface 21 and arranged., will not be when radially extending because each lengthy motion picture is not connected to
Interact, such full bag enhancing set 1 is easier to radially extend when upper end sealing ring 2 is by axial compressive force, reduces
The hardness of upper end sealing ring 2.
In the various embodiments described above, full bag enhancing set 1 is the softer metal such as aluminum of copper silver or other materials,
This is due to that cartridge needs to bear high temperature action at work, and the full bag of other materials such as rubber enhancing set 1 easily exists
Failed during high temperature.But with the development of science and technology when synthesizing resistant to elevated temperatures rubber, full bag enhancing set 1 can also be selected
For this rubber.Full bag enhancing set 1 is can be seen that essentially in the elongated metal of lower edges tooth punching from Fig. 6 and Fig. 8
