Description
Technical field
The utility model is usually directed to field of waste water treatment, and especially, is related to time of the waste water of gas field high salt bubble draining
Receiving apparatus.
Background technology
Exclude to accumulate in the liquid in shaft bottom using bubble row's gas producing technology during the construction of natural gas fields, exclude meeting during the liquid of shaft bottom
Produce a large amount of high saliferous bubble effluents.
Foam gas producing technology be using plunger pump by surfactant (foaming agent) inject oil jacket annular space in wellbore effusion
Mixing, by the agitation of gas flow, is existed using the bubble effect of foaming agent, dispersion effect, drag reduction effect and washing effect
Pit shaft produces low-density resistance aqueous foam, reduces fluid density, improves the fluid-carrying capability of air-flow vertical lifting ability and gas well, so that
Achieve the purpose that to discharge wellbore effusion.Foaming agent is formed by compoundings such as surfactant, stabilizer, preservative, corrosion inhibiter.It is led
It is surfactant to want component, and general content is 30%~40%.Surfactant is a kind of linear molecule, by two kinds of different bases
Group's composition, one kind is hydrophilic radical, strong with the active force of hydrone；Another kind is lipophilic group, not accessible with hydrone.Table
After face activating agent is dissolved in water, when there is gas to enter surfactant solution, hydrophilic radical is aligned in liquid film, lipophilic group
Group then aligns the two sides inside and outside liquid film, and stable foam is formed by molecular force.
The high saliferous bubble draining in gas field is the waste water that natural gas together takes ground out of in recovery process with natural gas, mainly
For water flooding.In gas exploitation course, gas field development middle and advanced stage is particularly, to ensure gas production, need to be added a large amount of
The chemical assistants containing surfactant such as the foaming agent of expansion type, corrosion inhibiter, antisludging agent.To ensure foaming effect, it is desirable to blister
The auxiliary agents such as agent retention property under high temperature, high pressure is stablized, after this causes foaming agent with natural gas and the discharge of gas-bearing formation water, foam discharging agent,
Condensate and other materials form stable emulsion with gas field recovered water, and demulsification, layering difficulty are big, and water-quality constituents is complicated.Root
Monitor and analyze according to long-term follow, chlorion about 10000-50000mg/L, COD about 5000-60000mg/L in such water, petroleum-type
100-2000mg/L, ammonia nitrogen 50-200mg/L.Meanwhile recovered water containing foam discharging agent produces a large amount of foams during floor treatment,
Increase great difficulty to processing.
To these waste water, part oil gas field is handled using re-injection mode after pretreatment, but is caused very much on stratum such as Sichuan
Thickly area, re-injection difficulty are quite big.Discharged after being handled mostly using modes such as chemical oxidations at present, but with environmental management
The increasing of dynamics, at present many places taken measures the concentration of emission of the saliferous material such as chlorion in limiting emission sewage, such as
Chlorion concentration of emission has been limited in below 300mg/L by some places in part basin, it is therefore necessary to takes desalination plus depth
Treatment measures.Current desalination process for waste water mainly has evaporation, reverse osmosis, electrodialysis etc..
Low-temperature multi-effect evaporation is one of presently preferred desalting technology, cold with evaporating compared with the desalting technologies such as film process
The advantages such as condensate water quality is preferable, residual mother liquor is less, salt obtained by evaporative crystallization can make full use of as product.Evaporation condensed water has
Effect eliminates the inorganic salts such as chlorion and majority of organic pollutants in waste water, but since raw water quality is complicated, additive types
Numerous, wherein organic matter of light component etc. enters in evaporation condensed water in the lump in evaporation process with vapor, causes to evaporate cold
Condensate cannot reach reuse or discharge standard requirement.The indexs such as particularly COD, ammonia nitrogen, volatile phenol are difficult to control, it is necessary to further
Advanced treating is carried out to evaporation condensed water, realizes recycling.
Therefore, the organic matter in the waste water of gas field high salt bubble draining how is effectively removed, its recycling is realized, is this
Field technology personnel technical problem urgently to be resolved hurrily.
