Description
Technical field
The present invention relates to a kind of petroleum industry well head prosthetic device, more particularly to a kind of coiled tubing notch, which restores, repairs dress
It puts.
Background technology
With the continuous development of coiled tubing technology, coiled tubing oil recovery or coal bed gas development and application have been pushed,
Existing coiled tubing has flexibility well, and a roll of coiled tubing grows several kms, and conventional oil pipe can be replaced much to be made
Industry, continuous oil pipe operation equipment have the characteristics that Operating Pressure, continuously remove, and equipment volume is small, and duty cycle is fast, at low cost
Advantage, the exploitation particularly suitable for flowing well.Wherein, four ram preventer of coiled tubing has act foot in continuous oil pipe operation
The status of weight, belongs to dedicated wellhead blowout preventor, and existing four ram preventer of coiled tubing includes blind rams, shearing lock
Plate, slip flashboard and half envelope four flashboards of flashboard, wherein, after the completion of half envelope flashboard refers to operation, before shearing, need casing first
Annular space closing between coiled tubing, avoids blowout from hurting sb.'s feelings, and full envelope does not act also at this time, and only there are one dynamic close above four flashboards
Envelope, easily occurs blowout；Slip flashboard be need to shear after the completion of operation when, suspension is first fixed, at this moment passes through card
Watt step up coiled tubing and hung；Shear ram is to need to stay in coiled tubing in well after operation, carries out oil gas
It during exploitation, needs to cut coiled tubing by shear ram, blind rams refers to after the completion of operation or stop that needs are full during well
Envelope, both sides, which are suppressed, shuts oil well, avoids gas leakage leakage, when needing subjob again or production, opens blind rams and continues
Operation, but the cutting that coiled tubing is realized to scissors and hydraulic structure is usually used in existing shear ram, to cutting
The notch of knife shearing is "-" type structure, and top is due to the gap to cultrating into "-" type, without good treating method.
Chinese patent literature 206290235U, patent name are《Four ram preventer of coiled tubing》, disclose its shell
Blind rams, shear ram, suspension flashboard and half envelope flashboard, the housing both sides pair are sequentially installed in intracoelomic cavity from top to bottom
Title is equipped with four groups of fluid cylinders, and piston is respectively arranged in fluid cylinder；The piston inner end passes through hanging platform and corresponding full envelope respectively
Flashboard, shear ram, suspension flashboard and half envelope flashboard back end activity connection, outer end is connect with handwheel mandrel；The fluid cylinder it is interior
End is fixed with guide rod, and corresponding blind rams, shear ram, suspension flashboard and half envelope lock are inserted into the inner end of guide rod
In square groove below plate.The utility model indicates the problem of shear ram, that is, the coiled tubing sheared
Notch is flat, by improvement of cutter, is designed using diamond shape, so as to which shearing shape be made to be approximate circle.It is although above-mentioned practical new
Type improves cutter, but still still the liquid outlet quantity of coiled tubing is had an impact, portion without thoroughly solving the problems, such as notch
Divide the advantage that the liquid outlet quantity for counteracting coiled tubing is big and stablizes.
Therefore, it is this for four ram preventers of the notch of the existing "-" type widely applied in oil field
The liquid outlet quantity or gas output that affect coiled tubing of the severe incision of "-" type, to have since there are some in underground continuous oil pipe
The energy of poisonous gas, such as hydrogen sulfide, carbon monoxide etc., also stratum is not known, and the stratum energy of some oil/gas wells is high, simply
The reparation that four ram preventers carry out notch is opened, gently then causes to operate easy poisoning, well that is heavy then easily forming high-pressure well
The safety accidents such as spray, overflow, so, there is no the reparation works that dedicated fix tool can complete above-mentioned oil pipe notch now
Make, carry out the reparation of safety to "-" type notch therefore, it is necessary to design a kind of dedicated prosthetic appliance.
Invention content
The purpose of the present invention provides a kind of coiled tubing notch recovery and repaiies aiming at drawbacks described above of the existing technology
Apparatus for coating repairs the notch of "-" type by special equipment, repairs as circular notch, makes its liquid outlet quantity or gas output
Restore normal, and solve the regulation for oil well head exhaust emissions, avoid personal injury and environmental pollution.

7 downlink of housing repairs 8 uplink of mouthful internal model simultaneously, and drives 10 rotation of key set, until the bottom for repairing mouth housing 7 comes downwards to four locks
The top dead centre of the suspension flashboard 4 of plate preventer, continues to rotate and constantly adjust position, will by the T-slot for repairing mouth housing 7
Two pressed ends of "-" type notch are caught, and fix tight upper pressing cap 13 by connecting bolt again at this time, and key set 10 is fixed,
Key set is made no longer to rotate；Then, the top for repairing mouth internal model 8 is rotated forward, repair 8 downlink of mouth internal model and is repaired simultaneously on mouthful housing 7
Row, the reaming that "-" type notch is completed by conical structure 8.2 squeeze, and mouth internal model 8 is repaired and it is possible to repeatedly move up and down
With reparation mouth housing 7, expand notch rounder and more smooth；
4th, it injects nitrogen and removes notch and restore prosthetic device, specifically：Nitrogen injection device is connected to and repairs mouth internal model 8
Top, and start to inject nitrogen, nitrogen enters coiled tubing inner cavity by check valve and injecting hole, suppresses to 0.5 megapascal, stop
It only suppresses, then removes nitrogen injection device, then rotate transition connector sleeve 11 and entire notch is restored into prosthetic device from four flashboards
It is upper in preventer to propose, blind rams is then shut off, completes entire notch repair.
It should be noted that：When just starting that coiled tubing notch recovery prosthetic device is installed, transition connector sleeve 11
Top connects upper pressing cap 13 by connecting bolt 12, only screws in 1/3rd length of connection bolt, ensures that key set 10 is not pressed
Tightly, it can be rotated；
Reversion repairs 8 outer wall of mouth internal model and is equipped with raised round platform 8.3, plays limiting operation；Upper pressing cap and transition connector sleeve use split
The advantages of formula structure, is, first, reducing the assembling space of device, second is that difficulty of processing is low, reduces processing charges, third, behaviour
Facilitate, convenient for rotary motion early period of key set, after being pressed into upper pressing cap, retainingf key set avoids rotary motion.
Embodiment 2, difference from Example 1 of the present invention are that the bottom of reparation mouth housing 7 can be equipped with L-type slot, still may be used
The two of "-" type notch pressed end to be caught, then above carried, while the reaming of notch is squeezed by conical structure.
Embodiment 3, difference from Example 1 of the present invention are：The reparation mouth housing 7 of the present invention with repair mouth internal model 8 it
Between can be equipped with bearing, in this way, can be more prone to rotation, operation is more more effortless.
The above, is only the part preferred embodiment of the present invention, and any those skilled in the art may profit
Equivalent technical solution is changed or is revised as with the technical solution of above-mentioned elaboration.Therefore, technology according to the present invention
Any simple modification or substitute equivalents that scheme is carried out, belong to the greatest extent the scope of protection of present invention.
