Description
Technical field
The invention belongs to oil-gas field development field of tool, and in particular to a kind of rupture disk perforated casing box cupling device.
Background technology
Pressure break is one of Main Yield-increasing measure of oilfield prospecting developing, and perforation is an important step before pressure break,
Current perforating job mainly has conventional perforation and hydraulic jet perforation two types.Conventional perforation operation is by perforating gun lower going-into-well
Explosion perforate after the predetermined level of eye, and then makes formation fluid enter well, the operating type construction cost and risk it is higher,
Need professional construction troop, perforating gun and perforating bullet need the storage of specialty, transport and safeguard, perforation rear sleeve easily rises footpath, set
After pipe intensity decreases, control hole count perforation, current limliting sub-clustering pressure break implementation result is not good, also influences larger to oil-gas Layer；Waterpower is sprayed
Sand perforation is mainly the nozzle with high jet, and eyelet is ejected in target zone, allows formation fluid to enter well, this operation is to storage
Layer injury is much smaller, however, it stills need again to go out it from underground after the completion of first tripping in specific purpose tool, perforation, work of constructing
Sequence is complicated, and cost is higher.Moreover, horizontal well quantity increase in recent years is very fast, and uses current perforating modes in level
Task difficulty is also larger in well.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to propose a kind of rupture disk perforated casing box cupling dress
Put, it is not necessary to the special perforation tool of tripping in, sleeve body intensity is not destroyed, construction cost can be reduced, shorten the construction period, and energy
Reduce the difficulty of horizontal well perforation operation.
In order to achieve the above object, the technical scheme taken of the present invention is：
A kind of rupture disk perforated casing box cupling device, including box cupling body, it is circumferentially spaced on box cupling body to set
There is the projection axially extended, several openings radially are provided with each projection, each open interior is provided with one
Nut, is equiped with a rupture disk between nut one end and the bottom surface of opening, pressure cap, the pressure are equiped with the other end of nut
Cap forms the cavity of certain air pressure with nut and rupture disk, and one layer is scribbled in the pressure cap upper end can be from the softening film dissolved.
Further, 90 ° are spaced between the adjacent protrusion.
Further, the open amount in each projection is 3~4.
Further, the cavity air pressure is standard atmospheric pressure.
Compared with prior art, the beneficial effects of the invention are as follows：
Apparatus of the present invention and the sleeve pipe that is connected together lower going-into-well bottom and complete well cementing operation, without rising, perforating job
When, it is only necessary to opening is pierced through using high-pressure fluid, hole is then projected, therefore, during using the technology perforation, without tripping in again
Special perforation tool, can save a trip time, shorten duty cycle；For horizontal well perforation operation, traditional penetrates
Usually there is situation not placed in the middle in hole instrument, not only increases task difficulty, can also influence perforating quality, and the present apparatus directly against
The borehole wall is closed, is not in problem not placed in the middle, and technique is simple, thus reduce horizontal well perforation difficulty；On the other hand, tradition is penetrated
Hole instrument once, completes the perforating job of an interval per lower going-into-well bottom, and the present invention can be multiple described with one-trip string tripping in
Device, so as to realize the perforating job that multiple intervals are drilled under one time, efficiency is significantly improved；With the exception of this, perforating job
Carried out described in the present apparatus at opening, the structural capacity and intensity of institute's connection sleeve pipe are not destroyed.

Embodiment
The structural principle of the present invention is discussed in detail below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, a kind of rupture disk perforated casing box cupling device, including box cupling body 1, on box cupling body 1
Along the circumferential direction at interval of 90 ° provided with a projection 6 axially extended, three radially sides are offered on each raised 6
To opening 7, each inside of opening 7 is equiped with a rupture provided with a nut 2 between the one end of nut 2 and 7 bottom surface that is open
Disk 3, pressure cap 4 is equiped with the other end of nut 2, and the pressure cap 4 is collectively forming with standard atmospheric pressure with nut 2, rupture disk 3
Cavity (referring to Fig. 3), scribbled in the upper end of pressure cap 4 one layer can from dissolving softening film 5.
The operation principle of the present invention：
Before operation, when installing pressure cap 4 so that the pressure of pressure cap 4 and nut 2 and the cavity of the formation of rupture disk 3 is standard
Atmospheric pressure, so, the startup pressure of rupture disk 3 just can be controlled accurately, it is not necessary to considered strata pressure, and be applied to pressure
The softening film 5 of dissolving certainly of the upper end of cap 4, can keep apart each part in opening 7 with cementing concrete, and utilize itself soluble spy
Point, the ablation completely within a period of time prevents that cement is dead by opening 7 after well cementation with this；
During operation, device of the invention and the sleeve pipe 8 (referring to Fig. 4) that is connected together lower going-into-well bottom complete well cementing operation；
When needing the perforation to go into operation, using conventional oil pipe or coiled tubing, by straddle type leather cup instrument or double K344 instruments across being interposed between the present invention
Device two ends, are then boosted by oil pipe, after rupture disk startup pressure (3000-4000psi) is reached, are broken through rupture disk 3, are entered
And pressure cap 4 is gone out, subsequent hydraulic pressure continues high speed erosion, can reach within five minutes or so the neighbouring cement of pressure cap, opening and rock
To broken state, and then stripping forms hole.
