Cross and change the characteristic for injecting water to improve tar productivity, oil field is substantially carried out secondary, tertiary oil recovery at present.From the aqueous of underground extraction
Crude oil claims " Produced Liquid ", and the water separated by dehydration is referred to as " oil field extracted water ", also referred to as " oilfield sewage ".China is most of
Oil field comes into the middle and later periods of exploitation, and moisture content is generally 90% or so even up to 95%, therefore, at recovered water
After reason recharge to underground be oil field production indispensable program.
The leading indicator handled oil field extracted water is oil content and suspension.It is thousands of that reinjected water will inject underground
Rice, if water quality unclean (suspension is not up to standard or particle diameter of particle is exceeded) can cause to block the tiny gap in rock stratum quickly,
Make it difficult to the depth for reaching setting, it has been found that a part of oil field region reinjected water is difficult to recharge, even if using higher than general pressure
Power is also difficult to re-injection, causes rock stratum to block here it is reinjected water water quality before this is unqualified, for this by abandoned well.Cause
This, oil field wishes to improve re-injection water quality, generally improves a standard class, to meet that oil field extends wanting for well recovery cycle
Ask.

Realize oily sludge thing and suspended solid while separate and remove；
4) sewage after aeration precipitation tank is handled enters oil water separator, further removal step 3) in do not remove
Oil emulsion；
5) sewage after oil water separator is handled is by pipe-line mixer dosing coagulant, subsequently into tiny flocculation tank；
6) sewage after the processing of tiny flocculation tank enters high efficiency particulate air filter, oil emulsion, the SS further efficiently gone in water removal
Deng pollutant；
7) sewage after high efficiency particulate air filter is handled flows through ultraviolet sterilizer, kills sulfate reducing bacteria in sewage, corruption
Raw bacterium and iron bacteria etc..
Further, described coagulant is using aluminum sulfate, aluminium polychloride, ferric trichloride, bodied ferric sulfate, polypropylene
One or more in acid amides etc.；Demulsifier is using in cationic, anionic, nonionic, amphitypy ionic demulsifying agent
One or more.
Further, in described aeration precipitation tank, aeration precipitation tank bottom even is provided with aeration head, is set at middle part
There is dissolved air water release head.
