Description
Technical field
The invention belongs to disposing polluted water in oil technical fields, and in particular to a kind of oilfield sewage sterilizes Agitation Tank except iron.
Background technology
In transfer drive, profile control, water blockoff, polymer flooding and chemical flooding work progress, from fresh-water-saving resource and the angle of environmental protection
Degree sets out, typically directly using oilfield produced waste water prepared polymer.However oilfield sewage salinity is high, sulfate bacterial content
High, Fe2+Content height etc. when being used directly to prepared polymer, easily damages polymer molecule, polymer molecule is made seriously to roll up
Song, and pass through bacterial degradation, particularly Fe2+Redox degradation, cause polymer solution viscosity very low, tertiary oil recovery economy
It is of poor benefits.In order to solve the problems, such as using oilfield sewage prepared polymer, it is necessary to first eliminate or inhibit thin in oilfield produced waste water
Bacterium, Fe2+Activity, so as to improve the viscosity of polymer solution, reduce polymer concentration and tertiary oil recovery cost.
At present disposing polluted water in oil technology is mainly using fungicide, but requires the inorganic agent added in that must match somebody with somebody with polymer
5 property are good, i.e., do not influence polymer molecular structure and solution viscosity.This sewage treatmentmethod, which not only operates, controls difficulty larger,
Complex process, and cost is larger, and labor strength is big.203922896 U of Chinese patent CN《A kind of sewage is sterilized except iron
