Description
Technical field
The present invention relates to produced water treatment field more particularly to a kind of systems of oil field composite multi-functional fungicide
Make method.
Background technique
Contain certain crude oil in oil field extracted water, adds various medicaments, while companion again in exploitation and treatment process
With factors such as high temperature, high salinity, pernicious gases, complicated component causes the diversity and complexity of oil field extracted water.It is lonely
Island oil field by many years note is poly-, Simulation on whole pay zones, due to polymer, hydrogen sulfide, carbon dioxide, dissolved oxygen and bacterium etc. it is a variety of at
Point comprehensive function, for sewage unstable along Cheng Shuizhi for flood pattern, burn into structure is serious, easily causes after multi-purpose station processing
Pipeline blocking.Water injection well water quality is not up to standard, formation blockage, and injection pressure increases, and infuses poly- oil pressure height, tubing string blocks, well head is viscous
The problems such as degree reduces seriously affects production, or even influences recovery ratio.
Gudao oilfield have passed through 50 years Development histories, be currently in for three high, deep development stages；By along Cheng Shuizhi
Change Current Situation Investigation, four main indicators of reinjected water, " suspended solids content " and " SRB bacterium " evolution with distance phenomenon is dashed forward the most
Out.Polymer content is high in one side sewage, and anion HPAM is reacted with medicament is added, and generates in molecule aggregate, with water phase
Oil droplet, suspended matter and bacterium cause unstable material iron ion in water, sulfide equal size to increase, and unstable material generates precipitating
Water quality is further influenced, while corrosion product and dirt remove contamination also result in system jams not in time in pipeline and structures.Due to supplying
Flood pattern corrosion and scaling causes water mixing system pipe network fouling blockage serious；Water injection well water quality is not up to standard, formation blockage, injection
Pressure increases；The problems such as infusing high poly- oil pressure, tubing string blocking, the reduction of well head viscosity, seriously affects production, or even influence recovery ratio.
It is investigated by multi-purpose station sewage treatment process and along journey Water Quality Variation Analysis, finds four main indicators of reinjected water
In, " suspended solids content " and " SRB bacterium " evolution with distance phenomenon is the most prominent.Polymer content is high in one side sewage, yin from
Sub- HPAM is reacted with medicament is added, and is generated oil droplet, suspended matter and opsonigenous substance in molecule aggregate, with water phase and is polymerized to wad a quilt with cotton
Group blocks injection pipe network in the continuous deposition sedimentation of pipeline tube wall.Another aspect burn into bacterium cause in water unstable material iron from
Son, sulfide equal size increase, and unstable material, which generates precipitating, further influences water quality stability, while in pipeline and structures
Corrosion product and dirt remove contamination also result in system jams not in time.
In view of the above-mentioned problems, improving water quality stability, solves live flood pattern pipe network blocking and have great importance.
