Description
Technical field
the utility model relates to throttling and kill manifold compressed air blowing cleaner technical field, is a kind of well control with the high-pressure refractory mouth of ventilating.
Background technology
are according to " Xinjiang Oilfield well control detailed rules for the implementation " the 28. and (eight) bar regulation: throttling and kill manifold carried out pipeline purging once with compressed air in per five days from the installation; Usually the method that adopts is that air-blowing is swept the joint purging and unloaded the high pressure gauge purging; It is that choke manifold is equipped with air-blowing and sweeps joint that air-blowing sweeps that joint purges, but that the purging efficient of joint is swept in air-blowing is poor; And unload in the process of high pressure gauge purging, the work of purging not only bothers but also does not meet the well control standard, and need loading and unloading repeatedly, makes manometric thread cause very big wearing and tearing; Simultaneously again because the restriction of air blowing latus rectum, cause narrow-mindedly, purge weak effect, there is well control hidden danger; The main cause that the air blowing latus rectum is little is the thickness low LCL of multidigit mounting flange, does not have enough punching homes, and the aperture is amplified and can be communicated with the bolt hole cross.The thickening of choke manifold multidigit mounting flange, external diameter strengthens, and the kill manifold flange thickens, and external diameter is constant, makes down studding, is connected with the gate of control multidigit mounting flange, makes flange top become a forging solid, and the punching that distributes just can be installed as required.Choke manifold thickening flange is erect by regulation top high pressure gauge, pressure sensor is installed.Low-pressure meter is with 90 ° of angular valves and blow afloat the mouth installation in the side relatively, is mounted to 90 ° of cross spiders with top; Kill manifold thickening flange top is erect high pressure gauge is installed, and low-pressure meter is installed in the side with 90 ° of gentle mouthpieces of angular valve relatively; The aperture that these annexes are installed all can be amplified as required, can also solve on-site voltage-measuring voltage stabilizing in winter and treat that pressure meter freezes constantly; After amplifying the aperture, implement, need adorn other high-pressure stop valve of equal pressure stage by original method of installing; Press latus rectum φ 16mm screening 70MPa high-pressure stop valve, at present internal security reliable durable again seldom and mostly volume is loose, install at the choke manifold highest point; Both dangerous, influence attractive in appearancely again, the quality of valve must could be confirmed in pressure testing; Execute-in-place is pretty troublesome, and cost is higher.
Summary of the invention
the utility model provides a kind of well control with the high-pressure refractory mouth of ventilating; Overcome the deficiency of above-mentioned prior art, it can effectively solve, and existing high-pressure stop valve is dangerous in the installation of choke manifold highest point, influence is attractive in appearance, execute-in-place bothers, the cost problem of higher.
The technical scheme of
the utility model realizes through following measure: a kind of well control comprises body, plug and protection sleeve with the high-pressure refractory mouth of ventilating; Through hole is arranged in body, at the right part of body screw thread is arranged, the inboard of protection sleeve is fixedly mounted on the right part outside of body through screw thread; Plug comprises stopper rod and chock plug, is fixed with the chock plug of external diameter greater than through-hole diameter at the right-hand member of stopper rod; Left end at stopper rod is fluted; Stopper rod is positioned at through hole, and chock plug is clamped on the right-hand member outside of body through protection sleeve.
Be to the further optimization of above-mentioned utility model technical scheme below or/and improve:
The outer lug of annular is arranged on the body of
above-mentioned protection sleeve left, the metal gasket ring is arranged on the body between outer lug and the protection sleeve, the metal gasket ring is clamped on the right-hand member outside of outer lug through protection sleeve.
above-mentioned groove is the narrow taper in the left wide right side.
There is at least one hangnail ring of direction towards a left side in the outside of
right-hand body of above-mentioned screw thread.
On the body in
above-mentioned outer lug left side conical external screw thread is arranged, the screw thread of body right part is a rectangular thread.
above-mentioned outer lug is the hexagon nut.
the utility model reasonable and compact in structure, easy to use, through using polyurethane YT type sealing-plug, pressure high sealability effect more is good more, and red copper metallic seal gasket ring plays the effect of secondary metals sealing, guarantees the reliability of pressure-bearing; Therefore reduced potential safety hazard; The purging latus rectum increases, and the design of hangnail pipe is convenient to on-the-spot directly grafting tracheae line and is purged, and has improved purging efficient, has reduced labour intensity, has improved well control safety.
