Description
Technical field
It the utility model is related to Produced Water In Oil-gas Fields, Ngi process field, and in particular at a kind of Produced Water In Oil-gas Fields, Ngi re-injection up to standard
Manage device.
Background technology
Recovered water re-injection problem up to standard was carried out as long as decades, never had can adapt to differently for a set of shallow-layer type
Layer, the technique and technology of the disposal that can meet cost and the re-injection demand at scene with shallow-layer of difference extraction aqueous systems occur.
Generally the treatment process of produced-water reinjection and technology experienced three phases.
First, old three sections of oil removing removes the outstanding stage：Since the team for contracting re-injection problem of early stage is oil field original before 94 years
The secondary unit of oil, is not water process team, to the understanding understanding more skin of water treatment system, stratum and the formation damage factor
It is shallow.Therefore their thinking is exactly to filter, therefore the industry occurs and help solidifying+filtering using coagulation+flocculation+for many years【Sand filtration,
The various filtration apparatuses such as walnut shell filter】.Its depth is not related to inorganic salts, organic substance residues and mushroom over the ground
The depth that layer influences, belongs to the injected extensive stage of recovering the oil.Each oil extraction in oil field Xiu Bao factories are the main bodys in this field at that time.
2nd, the secondary filter stage：The characteristics of this period is 94 years to 2010, this stage petrochina foreign
Achievement in research, is directly formulated to SY/T5329-1994 reinjection standards.Belong to the transition stage of such sewage disposal.
In view of to the understanding deficiency of the standard, along with the system in this stage is using economic interests as main examination mark
The accurate historical stage.Cause each oil field and secretiveness is performed to standard, make a show more, implement few present situation.The stage is somebody's turn to do
Class sewage actual treatment depth is only behind old three sections+filtering and adds one section of secondary filter.This stage
What is slightly broken through is exactly：Common air supporting and suspended sludge technique have begun with some engineerings in each oil field.But in view of operation
The limitation of cost, two kinds of techniques could not also go to deeper level.
The SSF of Ou Taike【The representative company of suspended sludge technique】It is merely capable of solving total suspended matter, the oil-containing of part
Amount problem；Jiangsu Cheng Bo/Jiangsu Asia【The representative enterprise of recovered water air-floating apparatus】Air supporting be also only confined in suspended matter
With the seizure of polar organic matter-colloid/asphalitine, differ greatly with oil layer protection.
Until each oil field is successively into the middle and later periods of exploitation --- the stage of production is asked to old filed, just finds pervious cruelty
Re-injection protects increasing oil below and produces serious harm.The implementation status of re-injection water quality standard just causes each oil field high level successively at this time
Pay attention to.
3rd, the shallow-layer control stage：2011- is present.This stage be each oil field it is deep experience formation damage to oily area
What is carried out after the harm of stable yields the most thoroughly changes.
（1）Inorganic matter：After Accurate Analysis is carried out to recovered water, the inorganic ions for having harm to formation damage is divided
Class, the control carried out after each quantizating index for endangering ion is confirmed.
（2）Organic matter：Comprehensive analysis has been carried out to recovered water organic matter, influence factor and influence index is finally determined.
Finally confirmed to need the re-injection water quality standard reached according to above-mentioned conclusion, and build accordingly or technological transformation is carried out to existing re-injection station.
In view of to the deep understanding of extraction aqueous systems and various formation influence factors, the utility model is to water process row
Industry takes industry with oil and carries out coupling truly.The technique and technology of this re-injection water process are based on organic in recovered water
The multi parameters controls such as thing, inorganic matter, bacterium, pH value and the shallow-layer equipment of coordination.
