Technical field：
The present invention relates to high temperature and pressure wellhead for production, suitable for the engineerings such as electric heating and oil field gas injection exploitation, especially
A kind of high temperature and pressure well head thermal recovery valve Special wellhead device controlled heavy crude heat extraction and high temperature and high pressure steam.
Background technology：
With the high speed development of the national economy in China.The electric power needed and the growth of crude oil at double, for controlling steam
The valve of pipeline is more and more, while increasingly more viscous crude fields is by development ＆ construction, since viscous crude density is big and hardened,
The steam of high temperature and pressure need to be injected to dissolve viscous crude, while the corrosive substances such as sulfide in crude oil content is high.In well head
Complexes based on valve just play key effect.The steam of valve injection high temperature and pressure is first passed through to dissolve viscous crude.It is high
Warm high-pressure well mouth thermal recovery valve is exactly specially designed for this operating mode situation of heavy crude heat extraction and the defeated vapour oil recovery pipeline of high temperature and pressure
Manufacture.
The steam pipework of traditional viscous crude uses wellhead assembly, and flow resistance is big, and operating force is away from big, and inconvenient for operation, efficiency is low
Under.Entire pipeline is very long, extremely inconvenient, while equipment cost becomes larger.Flashboard due to not can solve sealing ring it is resistance to it is high with
The compensation after abrasion is used for a long time.Service life is extremely short, and new device was just needed replacing less than 10 months, causes great wave
Influence and a large amount of manpower of needs stopped work when taking and replacing to production.
Invention content：
The present invention seeks to propose a kind of high temperature and pressure well head thermal recovery valve special valve, have good airproof performance, flashboard lubrication
Condition is good, and open and close is light and solves the resistance to high compensation with being used for a long time after wearing of sealing ring.
The technical scheme is that a kind of high temperature and pressure wellhead for production, including tubing head four-way, the second four-way, gold
Belong to O-shaped sealing ring, the first to the 9th high temperature and pressure well head flat gate valve, combination sealing filler, high temperature and pressure adjustable balancing formula
Throttle valve；Tubing head four-way is set there are four interface, and first interface connects steam by the O-shaped sealing ring of a metal, second interface with
Third interface concatenates two high temperature and pressure well head flat gate valves i.e. first, second, and third, the 4th high temperature and pressure well head tablet
Gate valve, the 4th interface also concatenate the 5th and the 6th two hp-ht well by the O-shaped seal ring seal of metal, combination sealing filler
Mouth flat gate valve；Equipped with the second four-way, the first interface of the second four-way connects the second end of the 6th high temperature and pressure well head flat gate valve；
The second interface and third interface of second four-way connect the 7th and the 8th high temperature and pressure well head flat gate valve respectively, and the 7th and the 8th
High temperature and pressure well head flat gate valve connects high temperature and pressure adjustable balancing formula throttle valve, the 4th interface connection of the second four-way respectively
9th high temperature and pressure well head flat gate valve and bull plug, bull plug connector are used to connect oil well mouth.
4th interface of tubing head four-way and the first interface of the second four-way point-blank, the 4th of tubing head four-way the
What is connected between interface and the first interface of the second four-way is that the O-shaped seal ring seal of metal, combination sealing filler also concatenate the 5th
With the 6th two high temperature and pressure well head flat gate valve.
The course of work of the present invention：When two high temperature and pressure well head flat gate valves on the right of device lowest part are opened in figure,
High steam is injected, when being recovered the oil top high temperature and pressure well head flat gate valve and high temperature and pressure adjustable balancing formula section
It flows valve to open, if all valves are closed, closes entire channel, terminate the steam injection of high temperature and pressure and recover the oil.
The present invention uses the O-shaped seal ring seal of metal.
Advantageous effect：The present invention ensures steam port under working condition at high temperature under high pressure using the O-shaped sealing ring of metal
Sealed reliable；High temperature and pressure well head flat plate gate valve gate plate uses slab construction, and no flow resistance can carry out recovering the oil or injecting
High temperature and high pressure steam.Using high temperature and pressure adjustable throttle valve, spool uses the adjustable type structure with balancing device, ensures to adjust
Accurately and reliably.4th interface of tubing head four-way and the first interface of the second four-way are cut in straight line and high temperature and pressure thermal recovery
Only valve uses single flow structure, and flow resistance is small, and flap uses damping structure, ensures sealed reliable.High temperature and pressure well head Flat Sluice
Valve ram seal uses novel enhanced soft graphite special construction, and the breakable problem of the soft graphite of solving over ensures
Sealing performance under the conditions of high temperature and high pressure condition.Filler uses composite structure, ensures the reliability of sealing.Using different types of
Carbide reactor welding technology makes sealing surface corrosion-resistant, impact resistance, ensures the service life of device.The present invention is used for using oil recovery field
Integrated wellhead for production with going out oil field, saves big quantity space, reduces investment outlay, convenient for management.
