Description
Technical field
Defeated decompression is mixed the utility model is related to a kind of totally-enclosed and recycles gas lift system, belongs to exploitation of oil-gas field technology neck
Domain.
Background technology
With the increase of productive life, different degrees of hydrops is had in the natural gas well and is generated, hydrops can lead to the production of gas well
Measure deep fades even stop-spraying.Current water drainage-gas recovery technology method has tapping mode（Closing well is pressed again, and throughput reaches when driving a well
Minimum takes aerogenesis drain after flow quantity）, bubble row（Hydrops foamed is set to reduce the kinematic viscosity and relative density of hydrops）, plunger gas
It lifts（Rise drain by piston gas-powered fluid column）, underground vortex（Liquid rate is taken by eddy current effect raising gas）, gas
Lift drain（Pass through oil pipe drain in oil jacket annular space injection high pressure gas）Deng, wherein gas lift liquid drainage technique is for watered-out well and production
The gas well of tolerance wretched insufficiency reproduces and increases production the effect for having and getting instant result.

According to the exploitation basic principle of the general natural gas well, the height of well head oil pressure determines gas well yield and gas
Fluid-carrying capability.Under normal circumstances, well head oil pressure and outer defeated gas well when being pressed with pressure difference just have natural gas output and form yield, outer defeated
Pressure is generally dependent on the well head ductwork pressure in entire oil field, and general is metastable.Middle and later periods gas well shaft bottom pressure itself
Constantly decaying, and the defeated pressure of outer wellhead is stable, so, the pressure difference of well head oil pressure and outer defeated pressure smaller and smaller can cause yield anxious
Play decaying.Gaslift technique is actually to increase bottom pressure, keeps stablizing output, and takes comparable pit shaft and shaft bottom product out of
Liquid.The discharge of pit shaft and shaft bottom hydrops is so that the static pressure difference for the mill resistance and wellbore effusion that gas flows in pit shaft further subtracts
It is few, in the case where bottom pressure is stablized, well head oil pressure can be further increased, realizes steady production.
Current gas lift liquid drainage is realized by vehicle-mounted flowing gas lift liquid drainage device, if it is using this gas well gas and outside
When air source of the gas transmission as compressor, will generally carry out pre-treatment to air source, in gas moisture content and sundries separation it is laggard
Enter fluid reservoir to be transported with waterwheel, due to containing a large amount of liquid in many block gas wells, so causing secondary outer row and transport same
The a small amount of gas overflowings of Shi Huiyou can not accomplish that totally-enclosed conveys, lead to the of high cost of gaslift and the pollution to environment.
