Abstract
The invention provides a high-seal leakproof oil production wellhead device which is composed of a tubing head part and a Christmas tree part. Nine flat gate valves are arranged, two needle type throttle valves are arranged, and sealing gasket rings and threaded flanges are arranged among the flat gate valves and between the flat gate valves and the needle type throttle valves respectively and are fastened through double-end bolts or threaded bolts and nuts. A stop valve is used for controlling and protecting a pressure meter and can also be used as a device and used for replacing the pressure meter. Three flat gate valves are arranged on a Christmas tree channel and serve as the main flat gate valves. The channel can be intercepted by closing any one of the flat gate valves. In the using process of the flat gate valves and the needle type throttle valves on both wings of a Christmas tree, a single wing is usually used. The high-seal leakproof oil production wellhead device has the advantages of being convenient to mount, safe, reliable, excellent in sealing performance, resistant to wear and corrosion, long in service life and the like and can be directly used for normal oil production, efficiency is improved, and a positive role is played in safe production and yield increasing and stabilizing of an oil field.
Description
Technical field
The present invention relates to the oil and gas wellhead device field of oilfield machinery, particularly relate to a kind of wellhead for production of high sealability anti-leak.
Background technology
Along with oilfield development process and the prolongation of production time, the multinomial technological measure workload of oil well increases increasingly.Wellhead assembly is the visual plant ensureing that oil well is normally produced, although particularly wellhead for production is of a great variety, structure is also had nothing in common with each other.But along with the increase of access times, its weak point shows especially day by day, and its component often damage, maintenance difficult, and it does not have good hermetically-sealed construction, easily causes the generation of leakage accident, can not realize multinomial process operation reliably, application life is short, adds the cost of winning of enterprise.After completing fracture acidizing operation, can not directly complete follow-up oil producing operation, inefficiency, use trouble.Simultaneously, the sealing of oilfield machinery oil and gas wellhead, widely used is not only large but also heavy Wellhead packer, the packing box must shut down and could continue and add packing is equipped with on top, oil well after long-term use, owing to there is inequality in oil pumper or well head basis, cause well head or oil-pump base TS to be directed at sucker rod partial wear and make wellhead sealing inefficacy leakage of oil, find not in time, oil-spraying may be there is, at this moment need to shut down and again add sealed packing, current art provides a kind of oil well sealer of adjusting center, though solve and must shut down the problem that could continue and add or change new packing at present, can continue under not stopped status and add sealing filler, the Wellhead packer used when eliminating the not only large but also heavy well workover of well head, solve the eccentric wear problem that the sucker rod of oil pumper and well head decentraction produce within the specific limits, but labour intensity is large, environment is dirty, also can cause the minimizing of output.
Summary of the invention
Order of the present invention is exactly bad in order to solve wellhead for production sealing effectiveness in prior art, directly can not carry out the problem of follow-up oil producing operation, overcome above-mentioned deficiency of the prior art, provide a kind of wellhead for production of high sealability anti-leak.
For achieving the above object, the present invention is achieved by the following technical solutions:
A wellhead for production for high sealability anti-leak, is made up of tubing head part and production tree part.Described tubing head part comprises plug, thread flange, flat gate valve, stud, nut, studding bolt, tubing head four-way, pressure meter, stop valve, meter connector, gasket ring, tubing hanger, jackscrew pressure cap, lower Packing seat, filler, upper Packing seat, jackscrew, two public short circuit, described production tree part comprises crossover flange, gasket ring, studding bolt, nut, flat gate valve, stud, little four-way, plug, thread flange, needle-like choke valve, it is characterized in that described thread flange and plug, thread connection between meter connector, gasket ring is had between flat gate valve and thread flange, connect with stud and nut, flange is passed through between flat gate valve, connect with stud and nut, gasket ring is had between tubing head four-way and flat gate valve, connect with studding screw bolt and nut, tubing head four-way is built with tubing hanger, two public short circuit, jackscrew pressure cap, lower Packing seat, filler, upper Packing seat, jackscrew, pressure meter and thread connection between stop valve and meter connector, gasket ring is had between tubing head four-way and crossover flange, connect with stud and nut, gasket ring is had between crossover flange and flat gate valve, connect with studding screw bolt and nut, flange is passed through between flat gate valve, connect with stud and nut, gasket ring is had between little four-way and flat gate valve, connect with studding screw bolt and nut, plug and thread flange thread connection, gasket ring is had between thread flange and needle-like choke valve, connect with stud and nut.
Described flat gate valve has 9, and needle-like choke valve has 2, all has gasket ring and thread flange between each flat gate valve, between flat gate valve and needle-like choke valve, by with stud or studding screw bolt and nut fastening.
Described stop valve is used for control and protection pressure meter, is also used as device, exchanges pressure meter.
Further illustrate the operating principle of the wellhead for production of high sealability anti-leak:
Tubing head four-way 7 both wings flat gate valve, in use, general use single-blade, single-blade passage upper flat plate valve has two, any cut out flap type just can block passage, but the flat gate valve inside tubing head four-way 7 both wings does not generally use as operating valve, when other flap type occurs blocking passage when leaking, the valve of replacing leakage that can be safe.
Production tree passage upper flat plate gate valve has three, is main flat gate valve, and close arbitrarily a flat gate valve and just can block passage, production tree both wings flat gate valve and needle-like choke valve in use, generally use single-blade.
Usefulness of the present invention is:
A kind of wellhead for production of high sealability anti-leak, by gasket ring and thread flange between critical piece, by studs and fastening nuts enhanced leaktightness effect, single-blade passage upper flat plate valve has two, any cut out flap type just can block passage, the valve of replacing leakage that can be safe, needle-like choke valve can be used in regulating channel capacity, be applicable to the needs of different well head oil atmospheric pressure and flow, in the middle of tubing head four-way, tubing hanger is housed, lower Packing seat, filler, upper Packing seat, two public short circuit, jackscrew and jackscrew pressure cap, operation is more reliable, product has easy for installation, safe and reliable, sealing performance is superior, Wear-resistant corrosion-resistant, the advantages such as long service life, directly can carry out normal oil producing operation, improve efficiency, to the safety in production in oil field, volume increase stable yields serves positive effect.
