Description
Technical field
The utility model belongs to a kind of oil field equipment, specifically is exactly that crude oil in the small-sized gathering system in oil field is carried out the airtight separator of crude oil gas-liquid that gas-liquid is partly or entirely separated.
Background technology
At present, there are two kinds of mode of movements in the oil field in the oil-gas gathering and transportation process: oil gas divides defeated and oil and gas multiphase flow.
All the well site is come oil to carry out oil gas in most booster stations and divided defeated operation, the well site comes oil to carry out next step storage, outer operation such as defeated again through the isolated crude oil of eliminator, and isolated associated gas is for the interior stove thermal source in station, and unnecessary associated gas then emptying is burnt.This way is contaminated environment not only, also is great waste for this non-renewable resources of oil simultaneously.
The part booster station comes oil to carry out the oil and gas multiphase flow operation in the well site, and the well site comes oil remaining oil gas behind eliminator separating part associated gas to transport to the next stop through output pump.Its shortcoming is exactly that this operation is difficult for controlling, and when gas-oil ratio is excessive, causes that easily slug flow can not carry out the continued operation of oil and gas multiphase flow.
Summary of the invention
The utility model purpose is to provide a kind of crude oil gas-liquid airtight separator, satisfy oil and gas multiphase flow at the same time, when dividing defeated two kinds of different process requirements, solve under oil and gas multiphase flow, the defeated flow process different situations of oil gas branch and can not carry out flexible operating, and the excessive slug flow problem that causes of oil and gas multiphase flow tolerance.
The technical scheme that the utility model technical solution problem is adopted is: the airtight separator of crude oil gas-liquid, it is characterized in that: comprise cylindrical shell, liquid ingress pipe, gas eduction tube, liquid delivery line, blow-off pipe, cylindrical shell is horizontal tank body, cylindrical shell is fixed on the basis by the saddle support, heat(ing) coil turnover pipe is arranged in the liquid ingress pipe lower end of cylindrical shell, and heat(ing) coil turnover pipe is located at end socket bottom, cylindrical shell right side; There is dish-like acceptor of energy at liquid ingress pipe inlet port place in the cylindrical shell, and dish-like acceptor of energy downside is established the buffer board of 45 ° of inclinations left, and demister is established in the center-right position of closed chamber in the cylindrical shell; Between the gas eduction tube of the relief valve port of cylindrical shell center top and left end, establish gasotron; The gas eduction tube downside has the air chamber of purification chord silk formula mist eliminator; There is blow-off pipe the cylindrical shell lower end and stretches into middle part liquid delivery line, the liquid delivery line of cylindrical shell; Have two position meter mouth and explosion-proof electric heating content gauge mouth on the left end end socket of cylindrical shell.
On the described cylindrical shell manhole is arranged, the bottom is provided with clean-out hatch.
When adopting the utility model to carry out the oil and gas multiphase flow operation, the gas mixture that comes from the well site enters in the jar from the liquid ingress pipe, after the heat(ing) coil heating, through buffer board, demister, portion gas is discharged behind the string silk formula mist eliminator by gasotron, remaining gas mixture is derived through middle part liquid delivery line in the oil gas mixed zone at cylindrical shell middle part, realizes that oil and gas multiphase flow is to next flow process; Carrying out oil gas divides when failing operation, the gas mixture that comes from the well site enters in the jar from the liquid ingress pipe, after the heat(ing) coil heating, through buffer board, demister, gas is discharged behind the string silk formula mist eliminator by gasotron, crude oil after the separation is derived through the liquid delivery line of cylindrical shell bottom, and isolated crude oil enters next flow process.Control valve is established in the liquid delivery line outlet of cylindrical shell bottom, by the pressure controlling of control valve, realizes the continuous conveying of crude oil.
Compared with the prior art the utility model has following advantage:
1, small scale, the Oil-gas Separation of suitable field, small-sized station, simple to operate, convenient management.
2, liquid delivery line one road stretches into the cylindrical shell middle part, and one the tunnel is located at the cylindrical shell bottom, can carry out oil and gas multiphase flow, branch flexibly
Defeated operation is fit to the different process needs.
3, establish dish-like acceptor of energy in inlet pipes, slow down the impact of gas mixture, changed the operation of mixture
Track prolongs the time of staying of mixture in cylindrical shell, can allow the abundant preheating of gas mixture, to isolate gas.
4, manhole, clean-out hatch, mudhole are set, make things convenient for the maintenance and operation of equipment.
